Homemade PCBs are usually soldered without verifying for their broken traces and short circuit connections. Though, this will take more time to finish but, it is to make sure that your PCB is working properly. Thus, after that, if anything goes wrong, you can focus mainly on wrong component placement.
To perform the PCB verification test, simply compare the PCB with the layout. During this stage, you might also want to test the connectivity of each traces to ensure no broken traces by using the diode function in the multimeter especially those with buzzer sound. This will ease the verification process as once we hear the buzzer sound, you will know that the trace is connected from one end to another.
To check for shorts, look at any suspicious traces that are too close and test using diode function in the multimeter as well. This time, if your buzzer sounds, then you know there is an unwanted shorts.
By doing these tests , it will help you to finish a working project faster. Additionally, this will also prevent components from damaged due to the short circuits.
