Their contract assembler had just delivered the first 100 boards. Despite a thorough design review and initial prototype, they found that each board needed rework at several BGA sites. The rework involved changing the circuit paths at the BGA sites, which required not only adding new circuits, but also severing the old circuits. The procedure that was developed to handle this problem ...

What about repairs to the non-functional parts of the board? Are "cosmetic" repairs even necessary? While the ...
