[ale] OT: Smoke Particles

[Mike Panetta]

Wouldnt it have to get through the soldermask first?  Traces on PCB's aren't
bare you know.  The worst it could probably do is get under all the BGA
parts and create shorts between the balls, but I think they would have to
be blown there under pressure to get in there.

Hat I'm trying to figure out is it smoke can corrode traces are cause
arcs between traces.
