BGA soldering is a process of packaging chips in a spherical matrix and connecting them to solder pads on a circuit board through solder balls. BGA soldering is a technically demanding and operationally complex process that requires strict adherence to process specifications and operating guidelines to ensure soldering quality and reliability of electronic products. The following are the main steps of BGA soldering:

Selection criteria for circuit board substrates

The performance and reliability of a circuit board largely depend on the selected substrate, which not only carries circuit components but also provides electrical insulation, mechanical support, and thermal management functions. Therefore, when selecting circuit board substrates, multiple factors need to be comprehensively considered to ensure the quality and performance of the final product.

How to choose between PCB hard board and FPC soft board?

According to their different materials and characteristics, PCBs are mainly divided into two categories: rigid PCBs and flexible PCBs (FPC). These two types of circuit boards have significant differences in structure, performance, and application areas. So, what factors should we consider when choosing PCB hard board and FPC soft board?
