I have a PCB with no solder mask with a very dense layout and a very fine trace spacing.
I didn't get a solder mask because it's still in the prototyping phase, and it's way cheaper.
I keep having to stop, find the new shorts that keep popping up, and remove metal fibers that are barely visible.
From what I can tell the fibers are aluminum from the pcb so a magnet is no help.
Is there a trick to remove them faster or a way to stop this from happening?
