Ghost circuit shorts under smt resisters only when they are located on solder side of pcb (glued down)

Electronics Forum | Fri Jul 23 14:07:52 EDT 1999 | Carl J. Odle

We are having a process related problem with pullup resistors on a controller card which has a I960 micro-processor. The controller monitors signal inputs and it's own resources then blinks a LED to indicate its working. The problem is that after a p
