Class04: PCB Manufacturing Method


PCB Manufacturing Method:


  • Photomask generated from the gerber file. 
  • Circuit pattern will be applied over the copper foil through photosensitive material.


  • Etching step remove the copper that is not the part of the circuit.

  • Milling is another method to remove the unwanted copper.

  • Once etching completed, vias will be made using drilling bits based on via diameter.
  • Now a days, vias with small diameter is made using laser.
