How to Outsource Medical PCB Parts

It makes no sense of investing heavily in production equipment if you want to make a few porotypes. Instead, it makes sense to outsource your Medical PCB Assembly and prototype manufacturing from a reliable supplier. But why not start a production line for your medical PCB parts? Well, there are several reasons why it is not a wise investment.

First, it is a heft investment. Since your primary business focus in not PCB assembly, investing in such a production line will be a waste of resources. Such assembly lines will cost you an arm and a leg. Also, with two businesses, you will not be able to focus on your medical supplies business. Also, starting a PCB assembly line requires a highly trained workforce and special machines, which are costly and require specialized skills to run. No matter how you look at it, ordering your medical PCB parts from a Medical PCB Assembly company is the right thing to do.

What should I pay attention to when looking for a medical PCB assembly company?

Now that you know that ordering your medical parts from a PCB assembling company is the right thing to do, where and how do you find a reliable assembler? Well, it might sound easy to head online and search PCB assembler’ on your favorite search engine. But you will immediately realize that there are many such companies and the choices will overwhelm you. If you are not keen, you may end up with the wrong company, and this only means you will get substandard medical PCB parts. This article will list tips to check for when looking for a Medical PCB Assembly company.

Many PCB assemblers will offer an instant quote mechanism on site for manufacturing and assembling PCB parts and prototypes. This saves you time when you are comparing different PCB assemblers. Make sure the quoting system allows you to enter every detail, such as thickness, milling, copper thickness, board material etc. This will ensure that you get a precise quote without surprises later.

Normally, the price per board decreases as quantity increases. This is due to the spiking setup cost of circuit board manufacturing. Some assemblers use a system where they combine boards from several clients. This way, they can distribute the cost of setup to several clients. When designing some medical PCB parts, you will start with a prototype, and since you do not want to have errors later, you should start with a few parts. Once you are sure what you want, i.e., when the prototype matches your needs, you can then go ahead and order quality medical PCB parts from a leading Medical PCB Assembly company.

One limitation with small quantity medical parts or prototypes is that the choice and thickness of the material is limited. If you consider using unique material, then chances are there won’t be any clients using the same material as your needs are custom. This will usually lead to high costs, but it is worth it as you will get custom parts or prototypes. Once you test the prototype and it is what you need, you will enjoy affordable prices once you get to mass production of medical PCB parts.

When looking for Medical PCB Assembly company, be sure to check to work with one that supports the file format you are providing. The most common format for medical PCB manufacture is Gerber format, but some vendors also accept board files types from some common PCB software products. Some PCB assemblers also offer in-house PCB design. If you handle the design work yourself, then picking an assembler offering professional design services is very useful in case there are problems with your order files. If your vendor can make some quick changes to your design, this will save you time and minimize delays.

When hiring a Medical PCB Assembly supplier, ensure that the company can assemble all the package types that your PCB board uses. Some assemblers cannot assemble some types of IC packages such as chip-scale, BGA, and some tiny component types. If you’re not sure if the PCB assembly company you are about to hire offers all these, be sure to contact them, let them know your needs, and explain what they can and cannot do. Do not compromise on quality as there many PCB parts manufacturers that can handle your needs. All it takes is research to find the right one.

Some PCB parts manufacturers will carry an inventory of standard SMT parts and also and through-hole parts. You will save lots of time if you can pull fro, your assembler’s inventory rather than buying each part yourself. Be sure to specify to your assembler the components you wish to restrict yourself when you are uploading your bill of material. This saves time and ensures convenience from both sides. It is an essential consideration.

Most Medical PCB Assembly companies also offer to manufacture SMT stencil, a requirement for PCB assembly. Always ensure that you order stencil when ordering the circuit boards to avoid delays. It will be great to get your parts on time, as this is good for your business. Therefore, it is essential to consider working with an assembler that offers a variety of services and parts.

Things to consider before ordering PCB medical components?

When ordering PCB medical parts, the last thing you want is getting parts that are malfunctioning or not working at all. Therefore, it is crucial to look for Medical PCB Assembly supplier that they have qualified in house engineers and experts to test your parts before delivery. Many suppliers will test your PCB parts before mass production to ensure functionality and durability. Also, it is critical to ensure that the assembler is licensed and certified. Besides having experienced team and certifications, you should also ask if the assembler offers a guarantee on quality for the PCB parts supplied. If they believe in their products, they should offer a warranty. This will build trust between the clients and the PCB manufacturing company, which is good for business.

Lastly, when ordering or finding a PCB parts vendor, be sure to check on delivery services. How does the delivery system work? When do you expect deliveries after placing an order? Who pays for the deliveries, and which locations does the company deliver? Getting all these answers will go a long way in ensuring you make the right decision.

The Best Digital PCB Assembly and Designing Process

Electronics are a vital part of our day to day lives. Everything from the smartphones to cars are available with electronic components. The Printed electric board can be said as the heart of all electronic components, which is also known commonly as the digital PCB.

A lot of people are immediately able to recognize printed circuit boards just by seeing these. These are green chips that get covered in copper parts and lines that you’ll find at heart of gutted electronic devices. These are made through copper lines, Fiberglass along with other parts of metal, all these boards remain held together with epoxy and are insulated through soldering mask. The solder mask would be where the characteristic green color would be available from.

However, did you ever observe the boards with the components stuck solidly on? These can never be regarded as only PCB board decorations. Advanced circuit boards are not able to provide functionality until components become mounted on it. PCB with the components mounted on is known as assembled PCB and the process of manufacture is known as the digital PCB assembly or in short PCBA.

The copper lines on the bare board are known as traces, the electrically linked components and connectors to each other. They run the signals between all such features, letting circuit board for functioning specifically in a designed way. Such functions mainly range from simple to complex, yet PCB size remains smaller compared to thumbnail.

How such devices are made?

The digital PCB assembly process is quite simple, and consists of various manual and automated steps. In each step of the process, the board manufacturer can select from both the digital automated and manual options and the one for selecting. For helping in better understanding of digital PCB assembly process from the start to finish. Thus, each step can be explained below.

The basics of PCB design

PBCA process begins mostly with basic PCB unit: base, consisting of various layers, with each one playing significant role in final PCB functionality. All such alternating layers have:

Copper: Thing conductive copper foil gets added for each of the functional PCB side – on one side if this remains a single-sided PCB, and on both sides if the PCB is double sided. The layer is of the copper traces.

Soldering mask: On copper layer top there is solder mask, providing each PCB with the characteristic green color. This insulates traces of copper from unintentionally contacting various other conductive materials, that results in a short. To simply state, the solder is meant for keeping everything in place. Solder mask holes are present where solder gets applied for attaching all board components.

This is an essential step to smoothly manufacture the PCBA as it can stop soldering from taking place on the unwanted parts with the avoided shorts.

The Silkscreen: White silkscreen is final layer present on PCB board. The layer is vital for adding labels in PCB in form of symbols and characters. This is ideal for indication of each component’s function on board.

The materials and components largely remain identical across all of the PCBs, with substrate being the exception. The PCB substrate material keeps changing accordingly with certain qualities – like bendability and cost – each designer looks for in the newest finished product.

Three of primary types of PCB are:

Rigid PCB: The common PCB base type is the rigid one accounting for most PCBAs. The solid rigid PCB core provides board with thickness and rigidity. The inflexible PCB bases are composed of all different materials. Common one is the fiberglass, otherwise it is designated as the “FR4”. The less expensive PCB can be made with materials such as phenolics and epoxies, though these being less durable ones compared to FR4.

Flexible PCB: the digital flexible PCBs provide more pliability compared to rigid counterparts. The digital PCB materials are bendable with high-temperature plastic such as Kapton.

Metal Core PCB: The boards can be another alternative to conventional FR4 boards. These are made through metal core; the boards can spread heat efficiently compared to others. This is helpful in dissipation of heat and protection of heat-sensitive components of digital board.

Thru-hole electronic components for digital PCB assembly

Electronic components with leads out and inserted through tiny PCB holes meant for soldering are known as thru=hole electronic components. The soldering or assembly process meant for such components also include hand soldering or the wave soldering – the Wave Soldering – PCB assembly process in solder in solder bar form are in high-temperature bath.

The solder remains in bath in the molten form and different forms with waves at high temperatures.

The temperature range can depend on molten form bath and creates wave at higher temperature.

The temperature range would depend on solder type

Conventional lead/tin solder is available with low melting point compared to lead-free one. PCB with thru-hole electronic component in the holes gets passed over the molted solder with conveyor belt help.

Entire wave soldering PCB assembly process requires following steps:

• Electronic component insertion
• Flux application
• Preheating
• Wave Soldering
• Cleaning and
• Testing

After the wave soldering of digital PCB assembly gets completed, it is now time for cleaning and testing. In case there is any defect for solder joint like blow hole or pin hole, it is again sent for rework, done through hand.

Manufacturing units available with lesser work load or reworking/repair jobs use hand soldering. Soldering iron or soldering station and solder flux and wire is mostly used for the process.

Digital PCB assembly with surface mount technology (SMT)

The Surface Mount Technology or the SMT is the PCB assembling process meant for the digital components of SMD. These components don’t have legs or leads. These get mounted on circuit board surface. The electronic components, equipment and various other soldering material is usable in the assembly process and is quite different from the thru-hole process of soldering.

Although the hand soldering is known to work fine for the PCB assembly requiring a lot of components present on both of the sides among which the SMD components remain more compared to the THT components. Therefore, being confronted with situation with small THT components required, the wave soldering is the suggested method.

Digital PCB assembly needs to go through various technical and complicated processes and various elements must be taken into consideration with little modification leading to high changes in costs and product quality.

Aluminum Based PCB Manufacturer: The Engineering Knowledge

Aluminum based PCB manufacturer has become popular over a couple of years. Electronic industries across the globe are turning towards aluminium-based Printed Circuit Boards. The unlimited advantages including flexibility, reliability, and efficiency have made these Printed boards an imperative part of modern electronics.

Aluminum PCBs are essential for modern and compact electronics. The great news is that Printed Circuit boards are no longer limited to just the traditional ones. On the contrary, today, we have numerous types of PCBs, serving different purposes.

In the course of this article, we are going to talk about one of the most popular Printed Circuit Board type, Aluminum Printed Circuit Boards. So, without any further delay, let’s learn about Aluminum PCBs.

Aluminum Printed Circuit Board

Aluminum Printed Circuit boards are extremely common among the light-emitting diodes. The reason being, they have a high heat dissipation factor. Below, we have briefly described the structure of the Aluminum Printed Circuit board.

Structure of Aluminum

Circuit Copper Layer

In the manufacturing of Printed Circuit board, the first thing that you need to do is to etch a copper layer. Most manufacturers use electrolytic copper foil for the etching process. It is important that the etching process is completed with the utmost care.

After all, the etching layer plays a vital role in PCB connections and assembling. The aluminum Printed Circuit boards have a greater capacity of carrying higher current. This is another reason; industries today prefer Aluminum PCB instead of the traditional FR-4.

Insulating Layer

The core technology of aluminum Printed board is its insulating layer. A good insulation layer ensures the quality and reliability of the Printed Circuit Boards. It also defines the heat conduction standards. The insulating layer of the aluminum substrate is perhaps the biggest barrier in the power module structure.

High thermal conductivity of the insulation layer ensures that the heat is spread uniformly and it does not cause any damage. The device’s decreased operating temperature ensures device efficiency, effectiveness, and extends its lifespan.

Metal Substrate

There are several factors that play a vital role in finalizing the metal substrate of the Printed Circuit Board. For instance, the hardness, expansion coefficient, surface state, thermal conductivity, cost, and several others.

When you consider all these factors, you would be easily able to narrow down your choice to one or two metal substrates. Focusing on different factors will help you choose different metal substrates. For example, if your main focus is on technical performance and reduced cost, you should talk to aluminum based PCB manufacturers such as KingPCB.

KingPCB would be able to provide diversity in terms of aluminum plates. For instance, you can choose from 6961, 1060, 5052 and so on aluminum plates. Aluminum PCBs work effectively for all electronics.

Aluminum PCB Performance

Below are some important performance factors of Aluminum Printed Circuit Boards.

Thermal Dissipation 

Some of the most common substrates of Printed Circuit Boards such as CEM, FR4 are poor thermal conductors. To ensure the longevity of the electronics, it is critical to dissipate their heat efficiently.

Lack of proper thermal dissipation would lead to high temperature resulting in complete machine failure. To avoid this particular issue, led PCB Board manufacturers now use aluminum substrate.

Aluminum is an excellent heat dissipation; therefore, it can effortlessly resolve this problem without investing additional cost.

Thermal Expansion

To alleviate the problem of thermal expansion on Printed Circuit Boards, the manufacturer now uses Aluminum substrate. Aluminum has excellent thermal expansion capability. The increased expansion ability of Printed Circuit boards has a positive impact on the electronic it is integrated into.

For instance, the thermal expansion of aluminum enhances the reliability and durability of its designated electronics. In addition, the aluminum substrate is excellent for resolving the SMT contraction and thermal expansion.

Dimension Stability

Another great performance factor aluminum Printed Circuit Board is its dimensional stability. So, far, we have learned that the aluminum substrate offers higher stability in comparison to the traditional insulating material of PCBs.

There is just a 2.5 to 3.0 percent of dimensional change in the aluminum substrate after heating it from 30 ° C to 140-150° C.

Types of Aluminum Printed Circuit Boards

When we say aluminum Printed Circuit Boards, we are referring to a number of aluminum PCBs. However, digging a little deeper would help us understand that there are several types of Printed Circuit Boards.

Below are the most common aluminum Printed Circuit Boards.

Flexible Aluminum Printed Board

Flexible Aluminum PCB is extremely efficient and effective for modern and compact devices. You can integrate it into extremely small devices. They compromise of three main layers including the conductive circuitry layer, flexible dielectric insulation, and the aluminum substrate.

All these three layers together make flexible PCBs the top choice. Led PCB Board manufacturers mostly offer their clients flexible PCBs especially when they are designing and developing small electronics.

To construct the insulation layer, the manufacturer uses ceramic plasters and polyamide. Using these materials ensures a higher level of thermal conductivity. They ensure that the heat transfer between the circuit to the aluminum substrate is smooth.

In addition, they ensure that heat energy scatters properly. Below are the perks of using Flexible Aluminum Printed Circuit Board.

Heat Transfer

The presence of aluminum along with the insulation layer ensures high thermal competences. In comparison to the fiberglass, the dielectric layer has the capability of transferring heat in a more reliable and efficient manner.

It can transfer heat ten times more efficiently. The effective heat transfer avoids any sort of destruction that would result due to overheating. It allows the circuity boards to smartly tackle a large amount of current.

Less Weight

Regardless of the type, Aluminum Printed Circuit Boards are extremely lightweight. So, it is safe to say that the flexible Aluminum PCB is also lightweight. The reason being, aluminum itself is not heavy at all.

Durable

The flexibility factor enhances the life of the Printed Circuit Board. This then has a favorable impact on its desired machine.

Less Price

Cost efficiency is the key feature of all types of Printed Circuit boards. The material, aluminum, itself is affordable.

Hybrid Aluminum Printed Circuit Board

In Hybrid Aluminum PCB processing of the nor thermal or insulating substance is completed separately. After that, it joins the aluminum substrate. You would need to use FR-4 resistance in order for it to have 2 and 4 layers.

When you use a non-thermal substance for construction it ensures high heat dissipation and high stiffness. In addition, you do not need a heat sink for Hybrid Aluminum Printed Circuit Boards.

Multilayer Aluminum Printed Circuit Boards

Aluminum Based PCB manufacturer offer multilayer Aluminum PCBs to industries producing power supplies modules. These Printed Boards use a massive amount of heat-conducting material.

Moreover, they come with an additional layer of dielectric material. They use a copper layer of the epoxy layer to cover the sheet of the insulated metal substrate.

Manufacturing Challenges of Aluminum PCB

Aluminum based PCB manufacturer uses all most the same process for the manufacturing of all Aluminum Printed Boards. Therefore, they tend to face some common challenges.

Copper Etching

The copper etching is among the most common challenge. Since the copper foil used for Aluminum PCB is slightly thicker, therefore etching it properly requires skills and the right machinery. Etching also needs width compensation.

Solder Mask Printing

Again, the thick copper causes a problem in solder mask printing. The thicker copper layer often results in a vast difference between the base board, and the trace surface. Thus, it would make solder mask printing a daunting task.

So, the manufacturers often use two-time solder mask printing. In addition, ensure that the solder mask oil is of great quality.

Take Away

Aluminum Printed Circuit Boards are the demand for modern electronics. Therefore, Aluminum based PCB manufacturer, such as King PCB, offer outstanding PCB manufacturing services. They ensure to deliver only high quality, reliable, and efficient Printed Circuit Boards.

They have vast experience, learned staff and modern technology to design and develop sophisticated and complex printed circuit boards.

Check the impact of flexible PCB in the modern mobile phone industry and its expected industry growth

What is a flexible PCB material?

The flexible PCB material includes a flexible substrate made of a dielectric layer. It provides a flexible substrate for conductive traces to be etched on it. For flexible PCB manufacturer with clear portability and flexibility requirements, flexible PCB materials are the best choice.

Polyimide or polyester materials can be used as the dielectric layer. Moreover, copper is also a common material for printed circuits on flexible printed circuit boards. The thickness of the copper layer here may be 0.0001〃 or less to 0.010〃 or more.

Due to the high oxidation tendency of copper, you need to cover the copper traces with a protective layer. Similarly, gold and solder are usually the materials of choice for this protective cover.

This is because gold and solder have excellent electrical conductivity and factor capabilities.

Generally, flexible PCB manufacturer use flexible PCB materials incorrectly. Moreover, it is consistent with a set of rules applied to rigid PCB materials. Flexible PCCB materials differ in how they are used to manufacture PCBs. And the applications they support.

The role of flexible PCB manufacturer in electronics consumer industry

FPC is mainly used in consumer electronics products, and mobile phones are its largest application market. According to Prismark data:

• the global FPC output value reached approximately US $ 12.8 billion in 2018 and
• is expected to reach approximately US $ 14.9 billion by 2022.
• with an annual compound growth rate of 3.87%.
• Downstream application structure, consumer electronics products are the main application areas of FPC.
• of ​​which smartphones and tablets account for 40% and 16% respectively.

Occupying the vast majority of the FPC downstream application market. In recent years, with the rapid development of automotive electronics, the proportion of FPC demand gradually increased to 14%.

flexible PCB manufacturer soldering process

Manually soldering the flexible board to the circuit board is the cheapest process of all flexible board welding processes. And some can even work without the use of jigs. But its welding quality is also the most unreliable process for flexible PCB manufacturer.

Because manual welding is easy to cause:

• empty welding
• Virtual welding
• false welding
• bridge short circuit and other quality problems.

This is because the soft board is easy to move. Or lift when the soldering iron head is removed and the solder has not been cured during manual soldering. After the solder is cured, false soldering and empty soldering are formed.

Therefore, it is best to use a heavy object to press on the soft board during manual welding until it is removed after welding. Furthermore, it can greatly improve the welding yield. In addition, the gold finger soldered on the flexible board is preferably opened with a through hole (PTH).

Simultaneously, it can increase the vision to confirm whether the soldering is good. And can also reduce the risk of short circuit of overflowing tin.

Laser soldering process by flexible PCB manufacturer

Laser soldering relies on the excitation of laser energy. To transform into heat energy to achieve the purpose of soldering. So, its soldering is usually used to directly heat the laser where it hits the solder. This process is simple for a professional flexible PCB manufacturer.

In fact, work bears feel that laser welding is not very suitable for FPC soldering on PCBs. Perhaps work bears have insufficient experience. Moreover, it is always thought that laser is more suitable for welding of connectors.

Because there are many FPC designs that do not have via holes. Subsequently, it causes the laser light cannot directly hit the solder. And the laser light cannot be fully heated.

In addition, this type of laser welding equipment is usually a dedicated machine and a non-universal machine. Its energy is generally not suitable for performing other operations. So the equipment cost is not cheap.

What is flexible PCB manufacturer prenatal treatment of flex pcb?

 

There are three aspects for a flexible PCB manufacturer that need to be dealt with in prenatal pretreatment. Therefore, these three aspects are all done by engineers.

1. The first is the FPC board engineering evaluation.Mainly to evaluate whether the customer’s FPC board can be produced. And whether the company’s production capacity can meet the customer’s board making requirements
2. unit cost.if the engineering assessment is passed. Then the next step is to prepare materials to meet each production link. Similarly, the supply of raw materials. And finally, the engineer processes the customer’s CAD structural drawings. Gerber line information and other engineering documents to suit the production environment. And production specifications of the production equipment
3. Then devolves the production drawings. And other materials to the production department. Various departments such as document control and procurement enter the regular production process.

The importance of flexible PCBs

You are already thinking, “ flexible PCB manufacturer have amazingly rigid PCB boards. Why do we even need flexible PCB materials? Well, there are several compelling reasons to support the transition to PCB-flex. Let us look at some of them.

Flexible PCB is easier to pack

We are now in the era of the rise of nanoelectronics. Generally, this means that we need to install more components in a compact area. Simultaneously, with a flexible PCB, this will prove easier than you think. Studies have shown that:

compared with rigid pcb, flexible pcb can save 60% of the weight and space.

These extremely tiny parts are now being welded with microscopes, tweezers and other small tools.

Flexible PCB brings more reliable and flexible components

Remember, flexible PCBs reduce the interconnection required. This means less solder joints and contact creases. Of course, this means that potential sources of failure are minimized and performance is generally improved. This is why flex pcb is now ubiquitous for flexible PCB manufacturer in medical applications.

At this year’s Consumer Electronics Show (CES), bug electronics companies launched high-profile flexible screen commodities in a high-profile manner. Allowing flexible screens to enter the masses’ vision for a while and become the focus.

The newly introduced flexible circuit board has significant advantages. Moreover, It is frivolous and easy to carry. Moreover, it can be folded into a paper and placed in the pocket of the consumer.

Currently, there are three major concerns for flexible commodities:

1. Flexible touch screen
2. Moldablecircuit board
3. Flexible battery

The increasing demand of flexible PCB manufacturer in mobile phone industry

flexible PCB manufacturer is contributing in mobile industry on massive level. Driven by the demand for thinner and thinner applications. Such as downstream smart phones, the share of FPC is expected to continue to expand.

With the rapid development of the downstream electronics industry in recent years. The demand for electronic products continues to expand and gradually develops towards diversification and customization.

As an important branch of PCB, flexible PCB manufacturer has more excellent physical characteristics than traditional rigid circuit boards.

• FPC can be bent

It can greatly reduce the volume and weight of electronic products. Furthermore, meet the needs of electronic products to develop in the direction of:

1. high density
2. miniaturization
3. thinness, and high reliability.

In recent years, the FPC market has sprung up. And its proportion has continued to expand. Subsequently, becoming one of the core driving forces for the growth of the global PCB industry.

Conclusion- flexible PCB manufacturer advantages

flexible PCB manufacturer divides FPC according to the number of layers. Similarly, FPC can be classified into:

• single-layer FPC
• double-layer FPC
• multi-layer FPC

Generally, related manufacturing technology is based on single-layer FPC manufacturing technology. Subsequently, through lamination technology Implementation, as follows:

FPC has the advantages of:

What is aluminum pcb?

It is a board in which an aluminum pcb manufacturer pastes a thin board is on an aluminum board.
Since it has excellent heat dissipation. It is ideal for circuits such as:

Pollution from aluminum pcb manufacturer process

Subtractive method is used in the process. Only after the through-hole plating. The full-plate copper plating method is used. That is, after the through-hole and the plate are uniformly plated to the required specifications by electroplating copper. The positive etching resist is transferred to resist corrosion.

A dry film resist is engraved to protect the copper surface where the lines and vias are to be formed. The copper surface that is not protected by the resist is etched and etched away. And finally, the resist is removed

aluminum substrate PCB production specifications- aluminum pcb manufacturer

.

An aluminum pcb manufacturer must protect the aluminum base surface of the aluminum substrate with a protective film in advance during the PCB processing. Otherwise, some chemicals will attack the aluminum base surface.

Resulting in damage to the appearance. And the protective film is very easy to be injured and cause gaps. It requires that the entire PCB processing process must be inserted.

The hardness of the milling cutter used for the fiberboard gong board is relatively small. While the hardness of the milling cutter used for the aluminum substrate is large. The speed of production of fiberglass milling cutters is fast during processing. While the production of aluminum substrates is at least two-thirds slower.

The computer milled glass fiber board can only use the heat dissipation system of the machine to dissipate the heat. But aluminum pcb manufacturer must process the aluminum substrate with alcohol for the gong head.

What is aluminum pcb manufacturing and substrate proofing?

Aluminum substrate proofing tells you the production specifications of aluminum substrate pcb:

The aluminum base surface of the aluminum substrate must be protected with a protective film in advance during the PCB processing. Otherwise, some chemicals will attack the aluminum base surface, resulting in damage to the appearance.

And the protective film is very easy to be bruised and cause gaps. It requires from aluminum pcb manufacturer that the entire PCB processing process must be inserted.

The hardness of the milling cutter used for the fiberboard gong board is relatively small. While the hardness of the milling cutter used for the aluminum substrate is large. The speed of production of fiberglass milling cutters is fast during processing. While the production of aluminum substrates is at least two-thirds slower.

The computer milled glass fiber board can only use the heat dissipation system of the machine to dissipate the heat. But the aluminum substrate must be processed with alcohol for the gong head.

 

The advantages of aluminum pcb manufacturing compared with traditional FR-4 board:

 

1. aluminum pcb manufacturer provides good thermal conductivity.

The metal layer of the aluminum-based PCB board can quickly dissipate heat. Transfer the heat of the device, minimize the thermal resistance, and have good thermal conductivity.

2. More environmentally friendly 

The aluminum-based PCB board does not carry substances harmful to human health. And the environment, and is more environmentally friendly than the FR-4 board.

3. High durability.

• LED energy-saving lamps
• driving devices for automobiles
• computers and other equipment
• audio equipment and power systems.

aluminum pcb manufacturer price

The same PCB, FR4 is priced at 30 yuan. And the aluminum-based PCB is as high as 950 yuan.

A considerable part of the LED lights on the market are aluminum-based PCBs. And they do not feel much more expensive than other ordinary aluminum pcb manufacturer. This shows that the cost of aluminum-based PCBs is not too high. Am I being arbitrarily quoted by profiteers?

 

Realization of the technology of conductive hole plug hole by aluminum pcb manufacturer

For aluminum pcb manufacturer in pcb mounting, the requirements for via hole plug holes must be flat. And the convex and concave are plus or minus 1 mil. And there should be no red or tin on the edge of the via hole. The via hole contains tin beads in order to reach customers.

The requirements of the via hole plug hole process can be described as varied. The process flow is particularly long. The process control is difficult. Often there are oil drops during the hot air leveling and green oil solder resistance test. Oil explosion and other problems occur after curing.

According to the actual conditions of production:

• the various plug hole processes of PCB are summarized.
• And some comparison and elaboration are made in the process.

 

Note: The working principle of aluminum pcb manufacturer hot air leveling is to use hot air to remove the excess solder on the surface. And holes of the printed circuit board. The remaining solder evenly covers the pad. And the unresisted solder lines and surface packaging points. It is the surface treatment method of the printed circuit board.

Demand for special printed wiring boards with heat dissipation measures is expanding. Previously, it was limited to some markets for backlights for LCD TVs. Mainly for lighting fixtures equipped with light emitting diodes (LEDs). But recently there is a movement to adopt high-brightness LEDs for car headlights is accelerating.

What is aluminum pcb manufacturing heat dissipation?

For aluminum pcb manufacturer, attention is focused on a metal-based high heat dissipation substrate. In which a high thermal conductive resin is pasted with an aluminum or copper plate. Furthermore, there are many cases where power devices such as power MOSFETs are mounted. And some ceramic substrates have been considered as alternatives.

It seems that progress has been made in the development of high heat dissipation resin substrate materials with a thermal conductivity of 10 W / mK class. And the advantages such as:

• cost reduction compared to competing ceramic substrates are evaluated.

 

Recently, aluminum pcb manufacturer has focused attention on aluminum substrates due to the evolution of LEDs.
An aluminum substrate is a substrate that is made of:

• an aluminum material and
• copper foil and
• an insulating layer.

Aluminum substrates have the advantage of being cheaper to manufacture than other metals. Since the copper foil is pressure-bonded with epoxy resin. It also has excellent heat dissipation, charging and processability.

Although releasing heat is called heat dissipation. If aluminum pcb manufacturer neglect heat dissipation, the life of the element will be shortened. And various problems such as deterioration of solder will occur, so be careful.
Other than aluminum, there are copper-based boards based on copper and iron-based boards based on iron.

But both have problems. Copper substrates are expensive, and iron substrates are not available to many manufacturers.

When choosing a board, it is important to know the aluminum pcb manufacturer characteristics. If you compare the power LED mounted on an aluminum board with the power LED mounted on another board, you can clearly see the difference in heat dissipation.
