Hi All, Hoping ya'll will have some brilliant suggestion to help me out... again!
Just received a batch of prototype boards. Added the through hole parts to two, and tried to power up. No power!
After a bit of testing, determined that my regulated VCC is shorted to ground! :-( So, I started looking for the obvious - solder bridges, vias shorted to an adjacent pad, going over my design files in detail for maybe an error on my part, etc. No joy, can't see where the error is.
So, my problem, how can I locate this elusive short. Any ideas? It is a populated board, so I can't just crank up current till it indicates the problem 'visually' (and aromatically!) ;-)
