We assume you're talking about scratches of the solder mask. One possible cause is: poor handling by stacking several boards on top of another and then moving them around, most often when carrying the stack of boards from one work station to another.

I would agree for a bare board house, are you NUTS? Look what happend to McCurdey's high tech line in S. Cal., go chewed up and spit out by China... Plating, etching, environmental issues, regulations, lack of people who like doing that work... endle

PCB BOARD - After removal of the BGA from the PCBA. In the midst of removal of the solder at the PCB, the green mask was scratched. If we do not repair the green mask, the whole board will have to be scrapped. Which repair kit do you recommend. W

Sarason, I will send you some samples. Note, however the .pcb file has a LOT more information in that just placement data, it has vision code definitions, part specific fields such as number of pick retrys, pickup/placement delays, speeds, feeder xy

On our machine it takes about 2 or 3 hours to make a program from scratch with an initial library(say 180 components per circuit, 10 identical circuits). If we had to do all the components from scratch I'd imagine it would take at least 10 hours pos
