What is the POFV process of PCB? Why use POFV technology?
The process flow of POFV has become more and more widely used in the PCB industry in recent years, especially in some products with high layers and large board thickness, which is very popular. People hope to use resin plug holes to solve a series of problems that cannot be solved by using green oil plug holes or pressure-filled resin. However, due to the characteristics of the resin itself used in this process, many difficulties need to be overcome in manufacturing to achieve good quality resin plug products. With the continuous updating of electronic product technology, the structure and installation method of electronic chips are constantly improving and changing. Its development is basically from components with plug-in feet to highly dense integrated circuit modules using ball matrix arrangement of solder joints. You can see the development history of parts from the following figure: In the PCB industry, many process methods have been widely used in the industry, and peop...
