Multi layer boards are not repairable if the problem is on an internal layer.
"IF" there is a fix, you will spend more finding the fix, and making the fix than a new board would cost. Single and double sided boards are nice to work on, and a technician can actually fix the circuitry on one. Even with the most exotic soldering station etc a bad multi layer board is trash. wrote in message ups.com...

Unless it's a very simple problem, in which case you can often jumper from one spot to another with a piece of wire wrap wire, of course finding that problem can be a real pain. |
