You're holding a board with base material damage - the board is beyond repair, right? Think again.
All too often, valuable circuit boards are scrapped due to base material damage. Actually, boards with base material damage can be reliably repaired.
The importance of knowing how to repair base material damage, rather than scrapping the board, may indeed make a significant impact on a company's bottom line.
A number of well established procedures exist for reliably repairing base material damage stemming from a variety of ...

A routing miscommunication resulted in a significant problem for a customer. The circuit traces for connectors on the left side of a double wide connector were supposed to route to the connectors on the right side. Unfortunately the opposite was true.
If the circuit board connectors were not rewired and the mating daughter board was plugged in, sparks would fly! Do to time considerations re-manufacture was not viable options.
The only option meeting the time constraint was good old fashioned jumper wire rework. In this case the rework involved four 64 pin connectors requiring 256 wires. That's a lot of wires in a very tight ...

The ground plane that should have served as a return path for signals was missing between plated through holes in a section of circuit board.
Thousands of boards were in the assembly pipeline, and thousands in the field, when a subtle disruption in the electronic operation of the final product became clear to the customer.
This problem existed between pads on a long row of closely spaced, plated through holes. Was there a way to rework these board without the obvious surface wires? We reviewed the possibilities and came up with a process ...
