Construct the circuit
In this week, I continue
back my progress on my circuit. I used printed circuit board(PCB). I choose
this circuit because it easier than use strip board. To customized PCB, all I need
are PCB board, acid hydrochloric, small drill, thinner and steel brush.
First, print the
circuit design to the PCB board. Print on glossy paper or photo paper. Iron the
printed design over the copper side of PCB. After the ink is transferring to
PCB board, dip the PCB into acid hydrochloric. After 15 minutes, rinse it with
water and rinse. The thinner are use to remove the ink. Use drill to make hole
for the component to be solder.
