1 Money IS an object, and my boss will be thrilled. The stencil manufacturer recommended ovals to facilitate better release. Seems likely to be true, but whether or not it's necessary I don't know. We have perpendicular walls on these (6 mil) ste

JC: Seen this before, many times. We fixed our problems at the co I work for by giving a packaging specification to our purchasing dept. Took some work but the payoff was pretty big. This document includes such things as orientation,pitch,tape type

well... it might be cheaper. But I think it's a bad idea. First, your operators will hate you by the end of the day with their sore feet, not to mention lost productivity. Second, safety. Even if the plates are connected to ground through a resistor

Thanks for the acvice, Dave and John. Like I stated above, I didn't feel comfortable with changing wave parameters since I knew that we'd be compromising our wave quality. I'll try the peelable mask thing, reprofile, and let you guys know what i fo

Hello Morris, I hope that my superiors don't see your message or they might have me go through all of that to calculate my cost per part mounted. One of the things that has helped me out considerably is an Accounting report that gives me all
