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 [...]
