It goes without saying that printed circuit boards are important for electronic devices. PCBs carry various electronic components that provide circuit connections and various complex functions for different devices.
When you learn to create circuits as a beginner, a breadboard would be a good choice.
Breadboards, also known as prototype boards, are solderless boards with one or both sides. Since the board has many small jacks, various electronic components can be inserted or pulled out at will as needed. Eliminating the need for soldering and saving time in circuit assembly, and the components can be reused, making it ideal for assembly, debugging and training of electronic circuits.
The common specifications of breadboard are 170 holes (35*47mm), 400 holes (85*55mm), 800 holes (165*55mm), etc.
Let’s look at some of the differences between PCB and breadboard
1. Application
Breadboard is suitable for the development stage and can change at will according to the demand. PCB is used for final electronic product integration, manufacturing and assembly according to Gerber files.
2. Components
One obvious difference between breadboard and PCB is that the components on the breadboard do not need to be soldered and can be changed instantly, so it is also called solderless breadboard. While the components on the PCB need to be soldered, such as SMT technology and PTH technology, so the PCB is also relatively more stable.
3. Capacity
There is no doubt that the load-bearing capacity of the PCB is significantly higher than that of the breadboard. Breadboard connects components through wires, so the current-carrying capacity is minimal. At the same time, PCB can also add a variety of components, but in the breadboard can not be completed.
4. Type
Breadboard is rigid, while PCB has a variety of options, it can be rigid, flexible, rigid-flexible combination to meet the needs of different scenarios.
5. Complexity
Even the simplest PCB has a much more complex structure than a breadboard. Usually breadboard consists of distribution bus and holes, PCB’s structure has at least substrate, copper layer, solder resist and screen printing.
6. Function
Breadboard supports components in a mechanical way, it does not perform electrical functions. PCB connects circuits in a mechanical and electrical way.
7. Appearance
The appearance of a breadboard is almost unchanging and relatively homogeneous. Whereas PCBs can be customized in various shapes, colors.
Choosing breadboards or PCBs?
If you are a circuit enthusiast or a beginner, breadboard can meet your needs. Breadboards can be easily prototyped and are relatively inexpensive. If you are looking for a long term, feature rich device, then a PCB is obviously the best choice.
Do you want to turn your breadboard prototype into a PCB?
After you have completed your development testing, you need to generate the Gerber files and Bom list for manufacturing your PCB. Then send these files to a professional PCB manufacturer, such as KingPCB, and we will carefully review your files and provide a quick quote, and then you can produce and assemble your PCB.

In order to choose the right PCB supplier for your application, you should conduct a thorough PCB quote comparison, which will help you to get the right PCB at the right price and with high quality.
Before getting a PCB quote, you should consider the following questions
– Does the manufacturer accept small orders for production
– What certifications the manufacturer has
– Delivery capability
– Manufacturing quality
– Is the quote competitive
– Can complex PCBs be manufactured
– Is the manufacturer responsive
Does the manufacturer accept small orders for production
You should pay attention to the minimum order quantity of the manufacturer you want to choose. Ideally, the manufacturer prefers to manufacture orders in bulk. Of course, for different manufacturers, some of the orders you think is a large order for the manufacturer is only a small order.
As for the different quantities of PCB manufacturing, the PCB manufacturing cost is also different. So please pay attention to the price provided in the minimum order quantity in the PCB manufacturing quotation.
What certifications the manufacturer has
For the purpose of producing high quality compliant PCBs according to industry standards, PCB manufacturers will go for relevant certifications according to the industry they serve. When getting a quote from a PCB manufacturer, you can ask if they have certain certifications. These certifications will also ensure that the products produced will not cause harm and damage to users.
Deliverability
PCB quotation is not only looking for the best price, but also looking for a full range of services. And the ability to deliver is an important test of a good PCB manufacturer. Your PCB manufacturer should have the ability to provide fast and timely delivery.
Manufacturing Quality
If the PCBs you order do not meet the standards, then your equipment will not meet the expectations of your customers. Quality control and quality assurance in PCB design and PCB prototyping help to keep the defect rate low. Even smiling mistakes can lead to huge losses, and this must be avoided as much as possible.
Is the offer competitive
There is no doubt that the most important thing in the quotation is the price. PCB manufacturing cost will affect your overall project cost, competitiveness and profit. However, the price of the PCB is usually influenced by three main factors.
-PCB design complexity
-PCB quality
-PCB volume
You can always find a cheaper quote, but in the long run, the cost will be higher. Regardless, you still have to choose the right and cost-effective PCB manufacturer for you.

Before learning about the PCB board materials we first know what is PCB. Also PCB is the Printed Circuit Board abbreviation. The main function is to support the circuit components.
1. CCL
Copper Clad Laminate as a printed circuit board manufacturing substrate material. It is the electronic glass fabric or other reinforcing materials dipped in resin.
One or both sides covered with copper foil and heated and made of board material. CCL conducts, insulates and supports the interconnection of printed circuit boards. Copper laminate has a great impact on the transmission speed of signals in the circuit, energy loss, and characteristic resistance. Where copper foils are in multilayer board production, they are also available as cores.
Copper foil is a cathodic electrolytic material. A thin, continuous metal foil deposit on the substrate layer of the circuit board acts as the conductor of the PCB.
The thickness of copper foil is normally in oz. 1 oz of copper is the thickness of copper foil spread evenly and flatly over a square foot area and is equal to 1.37 mil or 35 μm.
Common standards for copper foil are: 12μm (1/3oz), 18μm (Hoz), 35μm (1oz), and 70μm (2oz)
3. Preprag
Preprag is one of the main materials in the production of multilayer boards, consisting mainly of resin and reinforcing material, and multilayer printed boards use glass fiber as reinforcing material.
pcb board
The parameters of common PCB materials mean
94HB: ordinary cardboard, not fire-resistant (the lowest grade material, die-punched, can not do the power board)
CEM-1: single-sided fiberglass board (must be computer-drilled, cannot be die-punched)
CEM-3: double-sided half glass fiber board (in addition to double-sided cardboard belongs to the lowest end of the double-sided board material)
FR-4: Double-sided fiberglass board
Halogen: contains fluorine, bromine, iodine, and other elements
Tg: glass transition temperature, i.e. melting point. The general TG is 130 degrees or more, high Tg is generally greater than 170 degrees, and medium Tg is about greater than 150 degrees
pcb material comparation
The main standards for substrate materials are as follows:
1. Chinese standards: China’s national standards for substrate materials are GB/T4721-47221992 and GB4723-4725-1992, and the standard for copper-clad foil boards in Taiwan, China, is the CNS standard, which is modeled on the Japanese JIS standard and was released in 1983.

PCB Assembly -KingPCB’s Service
What is PCB?
PCB is an abbreviation for printed circuit board. PCB’s primary function is to house electronic components and make electrical connections in the electronic components. PCB can be single-layer, double-layer or multi-layer. In 2014, the global bare PCB market exceeded $60.2 billion and expectingto reach $79 billion by 2024.
PCB Types
Main PCB Components
Diode: it allows current to flow in one direction
Lead: light-emitting diode that glows when current flows through it
Resistors: color-coded components that allow current to flow through
Capacitors: design to retain charge for device operation
Switches: allow or prevent the movement of current
Inductors: passive components that resist sudden changes in current
Battery: links voltage to the circuit
PCB Manufacturing Process
Single-sided process flow
Board cutting → dry film (line) → etching → CCD drilling → solder resist → character → molding → surface finish → electrical testing → final inspection → packaging and shipping
Double-sided process flow
Board cutting→ drilling → sinking copper → board electricity → dry film (line) → lamination → etching → two drilling (some ranked in the solder resist and surface treatment after) → solder resist → character → surface finish (sinking gold some ranked in the character before) → molding → electrical testing → final inspection → packaging shipments
Multi-layer process flow
Board cutting → inner line → browning → pressing → drilling → dross removal → copper sinking → board electricity → dry film (line) → graphic plating → etching → two drilling (some are ranked after anti-soldering and surface treatment) → anti-soldering → character → surface finish (some are ranked before gold sinking) → molding → electrical testing → final inspection → packaging and shipping
PCB Assembly Technology
SMT assembly technology
What is SMT assembly technology? SMT is a method for assembling electronic circuits boardsin which components are mounted or placed directly on the top layer of a PCB. Compared to THT, components become smaller and placement of components on both sides of the board. It allowing smaller PCB components with higher circuit density. SMT is ideal for high automation, reducing labor costs, and greatly increasing productivity, and components can be mounted on carrier strips.
THT assembly technology
What is THT technology? THT is the insertion of components with tails or leads into drilled holes in the PCB, also known as feedthrough board assemblies. The leads are then soldered to pads on the bottom of the board, usually using a wave soldering process. THT mounting is very reliable because it creates a strong mechanical bond and the process is relatively mature. Compared to the SMT process, there are fewer variables that may cause solderable problems. The process can make bare boards more expensive due to additional drilling and the potential need to print on both sides of the PCB.
Hybrid PCB assembly
What is hybrid PCB assembly? As electronics tend to be smaller and more functional designs, this places higher demands on PCB assembly. It is challenging to assemble highly complex circuits in a limited space using only SMT or THT, combining SMT and THT technologies with appropriate adaptations to simplify soldering and assembly.
PCB assembly process
Solder paste printing: The first step is to apply solder paste to the board. The printed circuit board and solder stencil are held in place by a mechanical fixture, and the machine applies the paste to the stencil until it covers each opening area evenly.
Pick and Place: Using a mounter that automatically places surface mount components on the PCB. The machine picks up the PCBs with vacuum clamps and moves them to a pick and place station where the PCBs are. Then placed on the workstation and the SMD components are placed on top of the solder paste in the specified location.
Reflow: The circuit boards are transferred via conveyor to a large reflow oven. It heats the solder in the paste at high temperatures to melt the solder. When heating is complete, the board will pass through a series of ovens consisting of cooler heaters, which will help cool and cure the melted solder.
Check: The assembled board should tested functionally to check for bad connections. Common inspection methods include manual inspection, x-ray inspection, and automated optical inspection.
Through-hole component insertion: When the board assembling with other types of components, such as SMT or PTH, you need to use manual welding or wave soldering welding methods to insert PTH components.
Functional test: Functional test is the last step of PCB assembly to test the functionality of the PCBA. The test will simulate PCB operation and monitor the electrical characteristics of the PCB with power and analog signals passing through the PCB.
How to improve the quality of PCB assembly?
Choose proper component size: It is important to choose the correct package size for each component. It is advisable to choose a larger package. That is relatively easier to assemble the entire board again when disassembling and soldering the components.
Design reasonable component footprint: Component footprint is another key consideration for PCB assembly. Furthermore each package is created exactly according to the pad pattern specified in the data sheet for each integrated component.
Design suitable component spacing: Insufficient spacing between components caused by overheating, is one of the main causes of PCB failure. This situation is more obvious in some complex circuits. Redesign and manufacturing will be time-consuming and costly.
Ensure accuracy of the BOM: An error can lead to huge trouble, and manufacturers need to spend a lot of time identifying the problem. When there are new components or replacement, the client should update the BOM sheet in time to ensure its accuracy and validity.
Use of marker points: For use as a point of Mark points are very important for PCB assembly, especially when it comes to close spacing of components.

A Brief Guide about PCB Manufacturer – What is PCB Manufacturer?
In today’s Article, we are going to explain everything about PCB. Continue to read the complete Article; we will also reveal the name of world’s best PCB manufacturer. This Article is a full package because you will find everything at a single place.
There is lot of people who did not know about the full form of PCB because people commonly used to call it PCB but its full form is Printed Circuit Board. You got to hear its full form in very rare cases. Printed Circuit Board is an insulating material; it works as a backbone for all the electrical devices. In this advance era, you get to see all the electrical devices including Printed circuit board. They are made by utilizing nonconductive base board; manufacturers cut it to different dimensions and holes. There are many types of holes that can be used by PCB manufacturer according to their choices.
For example component holes, fasten holes, plated through holes etc. these types of holes plays an important role in making an interconnection b/w electronic components.
These days without Printed circuit board electronic devices are useless. There are two main purposes of PCB that you may have not known.
The very first purpose is to place to mount the component and second one plays an important role in creating electrical connection b/w electrical components.
These days technology has been very advanced so PCBs are made by using latest technology that prints the conducting layer in the form of micro circuit on main board. Because of this printing they are known as a printed circuit board.
When it comes to conductive layers they come into being by using copper thin foil. Aluminum PCB manufacturer, coat the board with solder mask in green color.Few of the PCB manufacturers also make use of blue and red one. In order to get the best results unwanted copper is removed from the substrate.
Pros of Printed Circuit Board that you may have not known
There is lot of advantages of PCB which makes them the best option for Aluminum PCB manufacturer in order tomake a good electrical device. In this advance era, almost 90% PCB manufacturer make use of PCB in electronic device in short electrical devices are useless without them.
Here we are going to explain advantages, have a look below.
Compact Size
In past, people make use of messy wires in order to create connection b/w components but these days because of PCB now interconnection are no more bulky.
In parts it was almost impossible to make connection of wires in small sizes components but now PCB has made this easier. Now you can easily create connection b/w small components.
In short we can say that PCB is a simple platform that allows the China PCB manufacturer to arrange components in a highly effective manner.
Easy to Repair and Maintain
Best thing about PCBs are that upon getting damage you can easily repair it. Besides repairing you can even replace the failure component.
Time saving
Those days are gone when you have to spend lot of time on messy wires. All those traditional methods requires lot of time in making interconnection b/w components whereas these days because of printed circuit board it has been very easier to make inter connection b/w components.
Immune to Movement
If you get a closer look on printed circuit board then you will get to know that all components on PCB are fixed just because of solder flux. It does not allow the components to make movement.
Strong Connection
If you make use of PCB then you can enjoy tight connections because usually China PCB manufacturer make use of copper tracks that make connection very tight and there is no possibility of short circuit at all.
Almost zero noise
PCB is getting famous day by day because it comes up with very low noise. But you have to make sure about laying down the PCB properly otherwise noise can affect the performance of circuit.
PCB usually releases noise in the form of heat, radiation and flickering sound.
Prices
Another plus point of utilizing PCB is that by spending a very lower price you can comes up with amazing results. You can get the mass production in very lesser price.
Reliability
When it comes to PCB they are highly reliable and bring high reliability in the performance of circuit but conventional methods were not good and reliable. This is why PCB has been famous among all the industries. It is not only limited to electrical industry; its widespread has been very high.
So these were the main advantages of Printed Circuit Board. Because of these advantages it has becomes first priority of almost all flex PCB manufacturer.
Aswe all knows every tech comes up with advantages as well as with some disadvantages. Now we are going to put shed over the cons of PCBs that you may have not known before.
Cons of PCB – flex PCB manufacturer
As well knows that copper tracks can be very thin so there may be possibility that it carry lesser current so if you are going to make a device that you think will bear heavier load then don’t make use of PCB.
If you use the PCB in such appliances then there may be possibility of strips getting heat up and can create problems. So you have to do the soldering process very carefully in order to avoid the chances of strips being over heated.
These were the advantages and disadvantages of printed circuit board hope now things are pretty much clear for you. As we have already explained that this article is going to be a perfect guide so keep continuing and read more about PCB.
Types of PCB – PCB Manufacturer
Although there is lot of PCB type but in this Article we are going to explain the most appropriate one.
Single Layer PCB
As its names suggest, this type is also called as single sided PCB. This is one of the most simply most popular types of PCB. This type is very easy to design and produce, it is very simple because on one side PCB board manufacturer have to coat the board with conductive material like copper. Why to choose copper? Well! We all knows that when it comes to high conductive material then copper is one of the best element to be chosen.
After coating one side with copper layer now PCB board manufacturer have to apply a solder mask. This solder mask plays an important role in protecting PCB against oxidation.
In single sided PCB only one side is utilize in order to make interconnection b/w different components. These components can be resistor, capacitor and inductor etc.
PCB board manufacturer can make use of single sided PCBs for BULK manufacturing applications for example calculators, radio and printers.
Double Layer PCB
Second type of PCB is double layer PCB. It is also called as double sided PCB. In single sided flexible PCB manufacturer applied thecopper layer on just single side but in double layer the case is completely opposite flexible PCB manufacturer apply the copper layer on both side from top to bottom.
This type of PCB is more flexible and comes up with lesser cost. Best thing about this type is that it reduces the size and makes the circuit very compact. You will get to see its wide usage in controllers, convertors, UPS, Phones, Amplifiers and much more.
Multi-layer PCB
You can have an idea by its name that it has been composed of multi layers. In this case, flexible PCB manufacturer applied thecopper layer on multi sides. But in this type you have to apply the glue b/w the layers of insulations. Doing this will keep the circuit safe from overheating. If you did not follow this rule then there may be possibility of damaging components sooner.
Though this type has many advantages but we will recommend you to use it for handling heavy electrical tasks. You will get to see its wide usage in applications like GPS technology, satellite system and medical equipment.
Flexible PCB
This one is a 4rth type of PCB; it is also popular among PCB assembly manufacturer because of its unlimited advantages.
Flexible PCBs comes into being by utilizing plastic like material for example polymide and PEEK.
Well it is one of the most complex types of PCB because it contains all the layers like single double multi. You will get to see its wide usage in Light emitting diode, LCD fabrication and flex solar cell. You will also get to see its wide usage in devices that are very complex for example laptops, PCs etc.
Rigid PCB
5th type of PCB is rigid PCB; this one is known as rigid because it is made by using solid material which doesn’t allow PCB to twist. Its layer configuration is as same flex PCB. Best part about this type is that after installation there will be no change in shape at all.
This is known as rigid because its shape cannot be bending according to base. PCB assembly manufacturer make use of it highly because of its durability. You can use this type in products like RAM, CPU, GPU etc.
This one is very complex especially the single sided rigid PCB is commonly used by PCB assembly manufacturer. Whereas when it comes to multi-layer rigid PCB then it can be very complexso PCB assembly manufacturer don’t prefer it more.
Flex Rigid PCB
This one comes into being by the combo of flex and rigid circuit. They contain multiple flexible PCB connected by rigid PCB. Flexi PCB manufacturer make use of these PCBcell phones, cameras and digital devices.
So these were the basic types of PCBs hope now things are clear for you. Continue to read the below content and knows about types of PCB according to Mounting system.
Types of PCB according to Mounting System
Through Hole PCB
This type of PCB comes into being by making holes with the help of drilling. On opposite side of PCB components are mounted to pads. We recommend this type highly because it comes up with lot of benefits; the very first benefit of this type is that it has capability to support the electrical components mechanically. Another plus point is that it is very reliable especially for mounting of components.
But it has one downside also; it is expensive as compared to other types especially drilling process makes it more expensive. if you make use of this type in single sided PCB then its implementation is quite easier but when it comes to double sided and multi sided then there might be possibility of difficulty in making holes so you can try it for single sided PCB without dealing any complications.
Surface Mounted PCB
Second type of PCB according to mounting system is surface mounted PCB. This one is more popular among Flexi PCB manufacturer as compared to Through hole PCB.
In this type components are small because of having zero leads on the components. But always keep in your mind that this tech needs mounting components on the surface of the board and Flexi PCB manufacturer don’t have to make holes on the board.
Both PCB types have its own advantages as well as disadvantages; you can choose the one according to your need.
Few Facts that you may have not known Before about PCB
These facts going to be very informative so give it a read and know about the fact that you may have not known before.
Why they are Green?
Few People mostly comes up with frequently asked question that why they are so green? So we are going to answer it here.
Green color is actually not a color that you see on the PCB; it is actually a solder mask. Here we are going to explain few theories regarding to its origin.
Few people come up with a saying that it was first used by military as a standard from there the use of green color became popular.
Few of the ones also comes up with a saying that green is the original solder mask resins color. in this advance era you can make use of any color for solder mask but green has proved itself a better and easy to find faults, this is the reason PCB manufacturer for hobbyist are still stick with it.
History of PCB – PCB manufacturer for hobbyist
PCB actually comes into being by Paul Eisler, he is an Austrian inventor. He invented it when he was working on Radio in 1936. But they were not so popular until 1950s.
After 1950s they started getting popular internationally among all the industries especially electrical industry 100% rely on PCB manufacturer for hobbyist. So this was the main history and a small overview about PCB.
They has been so popular
Well! PCBs are very ubiquitous board; if you get a closer look upon it then you can clearly see it. Yes PCBs are everywhere even the laptop, PC tablets all of these devices are useless without PCB. They have quickly made their positions strong and one of the quickly growing aspect of modern tech.
PCB manufacturer for hobbyist says that PCBs going to have a very bright future, few experts says that no other technology has capability to replace them.
Their Designing are done by CAD
If you are a newbie then we are damn sure that you must not have an idea that PCBs are designed with the help of CAD or computer aided designs. Prototype PCB manufacturer usually make use of CAD in order to design the schematic and layout of PCB.
This part is very necessary before heading towards the physical process, this tool will help you in inspecting the errors and you can also verify whether the traces are connected properly or not. If you find any malfunction then you can fix it and then can navigate towards the physical part.
Surface Mount Tech
You will not believe but this one is the most popular and the common manufacturing technique used to produce PCBs.
It has replaced the through hole method because of it’s amazing advantages. Through hole process is very slow and always comes up with lot of malfunctions this is why now Prototype PCB manufacturer gives first preference to surface mount tech.This method is one of the quickly growing method and widely used method after 1980s.
When it comes to Through holes Prototype PCB manufacturer has to attached the components to the board by putting leads into the hole but in the case of surface mount tech process is completely different, SMT sees them glued onto the pads on PCB.Because of this tech, manufacturing PCBs has been very easier, quick and time savvy.
Traces not Wires
As we all knows very well that in the past energy were transmit from one component to another component by making use of wires but now in this advance era PCB has completely change this conventional method. These days PCB makes use of electronic traces in order to transport electrons.
Because of traces PCBs are very compact and smaller in sizes, now Prototype PCB manufacturer don’t have to be in a messy wires.
few people thinks that it is not possible to make them by making use of through hole technology but they are mistaken because it is very easy to transfer the copper via hole in the circuit board.
Amazing Components
If you explore the PCB deeply then you will get to see lot of components and every component will have their own properties. Here we are going to give the main list of components resistors, potentiometers, capacitors, inductors, relays, batteries, fuses, transformers, diodes and transistors. These are the commonly available components and the important one.
Silk Screen
If you explore the PCB then you will get to see the white etching on the top of green solder mask. This white itching is actually a silk screen it actually plays an important role in identifying the component and information about PCB. it also help PCB manufacturer USA in finding the right component.
you will get to see white text in the form of silk screen print but these days because of modern technology now PCB manufacturer USA make use of digital printing by ink jet printers.
They can be personalized
Best PCB manufacturer like King PCB can customized PCB completely according to your choice. You can let them know your desired specification to them and they will come up with those specifications in affordable prices.
If you order custom PCB from other companies then the prices will be very high but if you try King PCB then the prices will be lower because they have amazing tool that can make manufacturing cost lower.
Change in the Tech
As we have already explained that PCB has been completely advanced and more popular since the days of Paul Eisler in 1936.
These days PCBs are compact and amazing in sizes. Soon you will get to see bio gradable PCBs also because they are evolving with each passing day. PCBs are not static at all; they will be developing more and more with each passing day.
Smaller
With each passing day Best PCB manufacturer are producing smaller PCBs. With through hole Technology PCBs were small but with the invention of surface mount tech PCBs are up to one tenth of the size of through hole circuits.
They followed Ohms Law
Best PCB manufacturer King PCB implements Ohms law in order to design and build world’s best PCBs.Ohms law main definition is thatit statesrelationship between current, resistance and voltage.
In simple words, Current is directly proportional to voltage and inversely proportional to resistance. So if you are newbie electrical engineer then you must have to follow these rules strictly.
What are PCBs made of?
PCB comes into being by making use of variety of materials. Material selection actually depends upon the requirement of device.
Best PCB manufacturer usually select the material that rely on the electrical performance, material will vary from device to device like high speed applications.
Here we are going to put shed over the most popular material used by PCBs.
FR4 Epoxy
FR4 is the popular and the most common PCB substrate in the world. Custom PCB manufacturer prefers it the most because of amazing thermal, electrical and mechanical properties.
It is a good option because it comes up with amazing strength to weight ratio this is the reason it is the perfect option among all material types.
FR4 made by glass cloth and epoxy resins, when it comes to price then this material comes up with the lowest cost. Custom PCB manufacturer make use of it in order to increase the PCB thermal and electrical performance. This material definitely should be your first preference because it is a highly versatile and can easily adapt all the manufacturing technics.
Polyimide
Our second preference is with the polyimide material. This material is different from Fr4 because it comes up with high temperature. Best part about this material is that it comes up with slightly improved electrical performance properties.
When it comes to prices then Polyimide are bit expensive because it has a capability to survive in the harsh temperature.
The reason to the selection of Polyimide is their stability during thermal cycling. You will not believe but it is true that they have less expansion characteristics this is the reason this material is appropriate with higher layer count construction.
Teflon Laminates
This one is also popular among Custom PCB manufacturer because of it offers high electrical properties. You can make it use for devices with high speed circuitry.
When it comes to prices then this material is very costly as compared to polyimide as well as FR4. You can coat Teflon on the glass fabric and can also be used with special fillers in order to improve mechanical properties. We recommend it highly but it is not for those Custom PCB manufacturers that have a tight budget.
Flexible laminates
These laminates are thin and popular because of having folding features. This material is built on plastic rather than glass fabric in order to provide support.
You can manufacturer this material from high temp material for example polyimide or very low material for example PEN.
Others
There are few others materials also BT, cyanate ester, ceramics, and blended systems. This material plays an important role in getting electrical and mechanical properties.
But 90% Custom PCB manufacturers don’t make use of such materials because of higher cost as well as the difficulty in manufacturing. Yes these materials are very expensive even beyond your expectations. This is why PCB manufacturers try the other alternatives like FR4.
Selection of right kind of material is very necassry for getting perfect electrical, dielectric, mechanical and thermal properties for application.
Hybrid PCBs
Have you ever heard about hybrid PCBs? We are damn sure you never heard about it. There are many manufacturers that laminate material into hybrid system. First one is known as rigid FLEX PCBs. Definition of Rigid Flex PCB is that it is a combo of flexible circuits as well as rigid laminates into hybrid solution. Advantages of hybrid solution are that you can enjoy benefits of both flexible as well as conventional circuits.
You will get to see few sections that will be flexible even you can bent them into any shape, you can even flex those sections multiple times without effecting electrical continuity.
There will be other sections also that will be rigid and provide you high routing electrical density. We recommend rigid flex method highly because we found it very flexible and one of the ideal package method for todays.

Different Parts of PCB
PAD
The very first part of PCB is PAD, it is nothing but a piece of copper. PAD is actually used to mount the components. PCB manufacturer makes use of PAD in order to done a soldering.
Trace
After PAD the second thing that you have to keep is Trace. If you explore the conventional method then you will get to know that those methods make use of wires in order to connect components but in PCB the case is completely opposite. Here you are completely free from messy wires.
In PCB you connect all components by making use of copper. This copper part used to connect parts actually known as a trace. In simple words you make use of traces for connecting components.
Layers
After tracing, 3rd important thing to consider is layering. You can do selection of layer on behalf of cost, and space of circuit. The very first layer is single layer, it is a simpler one because it is simple to construct, easy to design, and comes up with lot of benefits. But you cannot make use of single layer for larger products and appliances. If you feel that your device will be going to bear heavier loads then only prefer double or multi layers. These both are essential for complex or larger projects.
In this modern era, it has been easiest to utilize almost 10 to 12 layers for the things that you feel going to be very critical so choose the layer according to the needs of your products.
Silk Layer
Here after layering the next thing comes is silk layer. This layer plays an important role in printing. You can make use of this layer in order to print any text or information. In simpler words, this layer is used to label test or details for using PCB in a better way.
PCB manufacturer usually make use of epoxy ink for screen printing. Make use of silk layer on the top and bottom of the layer of PCB, you can ask the user also in order to fulfill their requirements.
Top and bottom layer
Well, components are mounted on the top layer of PCB. The most commonly used color for this layering is green because PCB manufacturers found this color safe and easy to identify faults.
When it comes to bottom layer then all the components soldered through the hole. Not only that, lead of components known as bottom layer of PCB.
Usually few manufacturers color these layers with green and then this color known as solder mask.
Solder mask
This one is the last layer and exists on the top of copper layer. This layer commonly known as a solder mask you can make use of any color for this layering but commonly used color is green.
PCB manufacturer make use of this layer just to prevent the contacts of pads with other conductive components on PCB. So in order to prevent accidental damage manufacturer make sure to coat the green color on to the copper layer.
If you are a newbie and working on a PCB project then you must follow this guide in order to come up with amazing results. If you forgot one layer then there might be a possibility of not perfect PCB.
