The role of blind vias is to conduct the left and right sides, so as to ensure the reliability of the circuit board! Blind holes are distributed in some layers, and buried holes are distributed in the middle layer, and through holes are distributed in all layers. Blind holes generally return All are

In the circuit board production process, the immersion gold and gold plating process are very common processes. Because these two processes solve the problem of the soldering process, the pads are difficult to flatten. As the society is strict with the function and size of electronic products As the

Today's electronic products are pursuing miniaturization and portability, which requires the core part of these electronic products, the pcb circuit board, to be smaller and lighter, which also requires the use of smt chip processing technology.The quality and reliability of solder joints in smt chi

A complete circuit board is composed of various electronic components, and it will go through many processes from PCB board to finished product, and SMT chip processing is one of the very important ones. To process a qualified PCBA board, you need to pay attention to many aspects. Next, Shenzhen PCB
