Troubleshooting the PCB line

After done with etching procedure, a PCB line should be check by using a multi-meter. This is important to ensure each component that will be install on the circuit board able receive a voltage and current and operate perfectly. Basically before soaking the copper board into the hydrochloric acid, the printed PCB line sometimes are not connected or dotted line. This problem can be fixing by drawing back those dotted line with a black marker pen and then continue soak the copper board into the acid.

Below picture shown the dotted line on the copper board

Making a connection troubleshooting using multi-meter.

Thus, the complete etching board will be drill to make a hole for electronic component placement.
