Final Year Project 2 (Week 8)

Week 8

Title of activity:

Etching process on the copper board according to the PCB layout

Procedure:

1. Clothes iron will be used to iron the PCB design to attach on the surface of copper board (Figure 1).
2. After attaching the PCB design on to the copper board. It will be placed into the etching acid. This process takes about 20 minutes to remove the remaining copper that is not needed (Figure 2).
3. The results of the etching process. Copper is not needed will be eroded, only copper that covered by carbon ink will remain on the board and form a circuit (Figure 3).

      Outcome:
