How and why to plate copper onto PCB?

Wednesday,Aug 17,2016

In Headpcb, we have 2 separate lines for plating process, one is automatic plating line and other one is manual plating line. Automatic plating line is suitable for mass production; while manual plating line is used for prototypes and fast production.


Plating on a PCB refers to the electrochemical process by which a metal is deposited onto the surface of the circuit board, and inside the plated through-holes. The most common plated metal in PCB fabrication is copper. Copper plating serves two purposes, it increases the copper thickness of the surface pads and conductors as well as providing a robust copper connection from layer to layer through the plated through-holes.
