The method typically used for high-precision fabrication of large-surface PCBs is acid copper electroplating, in which the PCB panel is immersed in an acidic solution of copper ions, the electrolyte.

Here’s a PCB fabrication process that makes us envious. It’s pretty darn close to fab-house quality at home. [Cpirius] is using a CNC mill and through hole plating technique to produce his ...

However, some of the titanium parts used in the electroplating process suffer substantial wear within a short space of time. Replacing these parts generates significant costs.
