□
Are there solder bridges on the solder side of the PCB
causing shorts? They are easier to find if you hold the
PCB toward bright light.
□
Are there bad/cold/dry solder joints? Jiggle component
leads at the solder joint with a pair of tweezers. Re-
solder them if any move. If a solder joint looks
suspicious, better rework it just in case.
□
Look if you missed a soldering point. With the USB
model, all pads are used.
