I think it is common as a last resort . . .

I prefer finding the actual short using other methods (thermal camera with voltage and current limited supply, ToneOhm, ShortSniffer, etc.), and then using a Dremel with a dental bit to guarantee the gap between the freed-up conductors is adequate.

Later,
Carl

Hi All,
Question, how common is the practice of using high current to clear bare PCB inner layer shorts?
Just curious,
Steve
