There is a very common process used in the surface treatment of circuit boards, which is called the immersion gold process. The immersion gold process is to deposit a nickel-gold plating layer with stable color, good brightness, flat plating and good solderability on the surface of the printed circuit. During the production, the cost of…
In our daily production, we will pay attention to the quality control of SMT processing, and ignore the cleaning process after PCBA manufacturing. We believe that cleaning is not a key technical step. So, where is the importance of PCBA cleaning for circuit boards? 1. PCBA production goes through multiple stages, and each stage is…
The pad is the basic unit of PCB surface mount assembly. So, do you know what the PCB Smt manufacturing process requires for pads? 1. Test points should be added to the pads where the two ends of the chip components are not connected to the plug-in components. The diameter of the test points is…
