Welding removal technique of SMT patch processing

What are the techniques for the dismantling of SMT patches?Generally speaking, it is not so easy to remove the SMT patch processing elements. Need practice frequently to master, otherwise, SMD components will easily be destroyed if forcibly removed. Here have three welding removal techniques of SMT patch processing. Kingford-PCBA-PCB-assembly-SMT-DIP 1. For SMD [...]

SMT chip processing need to pay attention to some of the issues

The development of SMT patch processing has brought an innovation to the entire electronics industry. Especially in the current environment. People pursue the miniaturization of electronic products. The perforated plug-in components used in the past can not be reduced to result in the large size of the entire electronic product. But nowaday, SMT patch [...]

How to quickly distinguish commonly used SMT components?

With the development of miniaturization and high efficiency of smt technology, all kinds of commonly used components are becoming smaller and smaller. The resistors, inductors and capacitors are difficult to distinguish in shape. So, how to quickly distinguish common SMT components? 1. The distinguish of inductors and capacitors: (1). Color--- Commonly, blask is inductors. [...]

How to design the dimension and board thickness of PCB?

The dimension of PCB depends on product design. The design need to consider the best utilization ratio of material, because the processing price of PCB is calculated according to the utilization rate of material. Fabricate of PCB, first, the substrate need to cut into a processing board, the dimension is 12"~21" x 16"~24". The [...]

What is the difference between gold plating and immersion gold?

In the PCBA chip processing, PCB board production is a very important aspect. There are many technological requirements for pcb. For example, customers require gold plating and immersion gold (ENIG) processes. Both of them are commonly technology for PCB. But they are very different. A lot of people will confuse them. So, what is [...]
