With the development of miniaturization and thinning of electronic products, many pcb circuit boards in electronic products are now using SMT manufacturing technology, namely surface mount technology, that is, all electronic components are welded on the surface of circuit boards.There is no need to insert it through the reserved holes in the circuit board and weld it on the back as before.

SMT technology can make the production process of circuit boards more automated, faster, and less human intervention. Moreover, the components used in this technology have the advantages of smaller size, lighter weight, and more reliable than previous plug-ins.

An SMT production line includes the following main parts: printing presses, placement machines, reflow ovens, cooling equipment, and some auxiliary optical inspection equipment, cleaning equipment, drying equipment, and material storage equipment.
