Circuit boards are more complex today than
ever before but despite how severely damaged
they may be they can be repaired. Indeed the
high value of many circuit boards demands
that they be repaired.
Just a few years ago circuit boards were much
simpler and repairs were relatively easy.
Today circuit boards have fine pitch
components ball grid arrays and fine line
circuits making them a challenge to repair.
Yet we’re driven by simple economics and must
repair damaged circuit boards whenever
possible. This manual is designed to help you
repair and ship good reliable circuit boards
that might otherwise be consigned to scrap.
Because of its high demands, pcb repair has been accurately compared to
surgery. Whether repairing surface mount pads
or repairing damaged internal circuitry, the
technical knowledge and manual skills needed
for high reliability repair and rework are
indeed demanding. Since today’s repair
procedures are more sophisticated than ever
The damaged sections of pcb were covered with the teflon tape and then all holes had to be replicated. If the copper track had lifted away, I simply glued it down with Loctite superglue .
