Kieth,

I thank you. My concern is what the "average" top 10% board shop can do. I know this is a loaded
question, but we have serious problems concerning a near 5 mil gap between a trace running parallel
to a 432 ball perimiter BGA pad pattern with obvious shorting/bridging problems. On about 50% of our
boards, received from a "top 10" shop, conductor edges are visible causing shorting, without serious
touchup (with silk screen epoxy hand applied goop) efforts.

I believe what you say. I know in my heart, as I have wittnessed it first hand, what you say can be
done. You say routinely and I do not question, but how routinely and under what conditions? What
kind of controls, or process management efforts, must be employed from photoplotting through resist
stripping?

Thanks and high regards,

Earl Moon
