WEEK 6 (FYP 2)

TITTLE : ETCHING PROCESS

This week, I continue with etching process. Begin the etching process using a acid liquid to remove copper that is non use for the circuit. After etching process used the sand paper to remove non use copper on the board until only the tracking one is there. The etching process must be completed first before it can install the component on the board using a drill and solder.
