PCB Manufacturing Process Flowchart – Step by Step Step-1: Patterning or Etching. Majority of printed circuit boards are manufactured by applying a layer of copper over the entire surface of the PCB substrate material either on one side or both sides. This creates a blank printed circuit board, with the copper everywhere on the surface.
