What are the difficulties in the processing process of Shenzhen PCBA factory?
What are the difficulties in the processing process of Shenzhen PCBA factory? Let the PCB engineer share it with you today.
The PCBA factory is a one-stop factory that can do everything from PCB proofing, SMT chip processing, component selection, DIP plug-in post-welding, and assembly testing. A qualified PCBA factory can deal with the following difficult problems:
1. Proof of various PCB circuit boards and light boards; including military-grade high-frequency boards, flexible circuit boards, ceramic substrates, characteristic impedance boards, metal substrates, chemical nickel gold boards, thick copper power boards, rigid-flex boards, etc. These PCBs of different materials have different requirements, and none of the customer requirements are the same. Therefore, to grasp the requirements of these PCBs and customer needs, the most important thing is to ensure quality, which is a difficult point. If there is a problem with this process, all subsequent processes will cause poor quality due to the mistake of the starting point.
2. SMT patch. The process includes: incoming material inspection, solder paste printing, SMT chip processing, DIP plug-in post-welding, assembly testing, first article inspection, etc., which must go through SPI solder paste detector, online AOI, offline AOI, X-ray, first article Detector, etc. In addition, any difference in the quality of the solder paste and the stability of stirring and soldering will cause quality problems.
3. Procurement and storage of components. Components, especially humidity-sensitive components, BGAs and ICs, have very strict storage requirements. If the preservation measures are not in place and all soldered components cannot pass the inspection, it is not only a rework problem, but also affects the customer’s product launch time. The necessary time cost output.
From the above three points of analysis, to overcome the difficulties in the processing process of Shenzhen PCBA factory, it is necessary to have strong technical strength. If you can do the above three points well, then this PCBA factory is completely worthy of your trust. iPCB is a high-tech manufacturing enterprise focusing on the development and production of high-precision PCBs. iPCB is happy to be your business partner.
