PCB Board Manufacturing
Patterning or Etching - Etching has anything to do with engraving but does not imply it literally. In this, the etch resist film exposes copper and other exposed unprotected places to remove the exposed copper. The shielded copper pads and traces are still in situ as a result. However, more recent and sophisticated processes for PCB board manufacturing employ plasma or laser etching rather than chemicals.
