Surface treatment process in FPC PCB production process

Today, as the electronics industry is growing, with the trend of light, thin, and short electronic products, the development of high performance and multi-function, and the improvement of electronic device soldering technology, flexible circuit boards (FPC) are also used for electronic mutual The connected circuit boards have been rapidly developed in the Chinese printed board industry in the past two years. Due to the demand for light, thin and short electronic products, the application range of flexible PCBs is [...]

Analysis of copper plating in PCB

First, the reason for PCB copper plating: 1.EMC, for a large area of ​​ground or power copper, will play a shielding role, some special, such as PGND to protect. 2.pcb process requirements, generally in order to ensure the plating effect, or the laminate is not deformed, copper plating for the PCB layer with less wiring. 3. Signal integrity requirements, giving the high frequency digital signal a complete return path and reducing the wiring of the DC network. Of course, there are heat [...]
