Introduction:Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). In industry, it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. Both technologies can be used on the same board, with the through-hole technolo...

Introduction:Rigid-flex PCB is a new type of PCB which has both the durability of rigid PCB and the adaptability of flexible PCB. Of all types of printed circuit boards, rigid-flex PCBs are the most resistant to harsh application environments and are favored by manufacturers of medical and military equipment.Compared with the common FR-4 rigid-flex substrates, the aluminum rigid-flex substrates have better heat dissipation performance and higher service life. The binding force of the PCB has a c...

Introduction of Application of Lead-free Surface Finish Techniques:Whether lead-free HASL can be popularized will depend on the results of the scientific study and its promotion and influence, but its smooth surface and high temperature process problems may be obstacles. OSP technology is widely used when a flatter surface is required, long shelf life is not required, and multiple heating applications are not required. OSP is likely to replace HASL technology in a large number of general applica...

Introduction:As the wiring density of flexible substrate becomes higher and higher, the circuit made by subtractive process can no longer meet the requirements of circuit elaboration. Therefore, the industry gradually turns to the semi-additive manufacturing process. At the same time, some thin flexible substrates and embedded flexible substrates manufacturing technology is also gradually applied in the production of mass production.Electrodeposition Polyimide Process:The protective layer of fle...
