I am hoping to find out what database format is used in the component library in the Universal Software for the 4785 chipshooter. The format is something like dbase or foxpro or access. This is an old program and I would like to connect to the comp

If you are doing this in a high volume, you could concider using a pin transfer method. Apply solder paste first. Have a plate made with retractable pins in the location you want to have the adhesive dots. Dip the pins into a lake of adhesive. Align

We have made a number of step up adhesive stencils using a new material called Cirlex. This material demonstrates excellent release characteristics and is easly cleaned. Typically the glue printing is after the solder printing. The stencil is all las

Chris, I should have read your request more carefully. .010" glue dot diameter would require at least .005" needle diameter. No way you can do it with the above mentioned machines. You are already stretching the capability of glue machines for 0402 c

Hey, Preacher, choir here. Unfortunately I didn't get to make the call here (hot boards, new product, same ol' same ol'), but I dam* well am looking for future (print) backup to assist in persuading the bottom line guys that it's cheaper to wait for

I am just starting to get into sub 50mil pitch, but from what I can see you are correct. But I can help with solder stencil. I cut the width only half of what the pad is, but the keep the length the same. This has helped but does not fix always. Stil

we bake boards 80~120 deg-C @1hr, after in-line DI wash. oven setting to 90 deg-C, as +/-5 deg-C, tolerance against door open/shut fluctuations = "temperature loss". If anyone has evidenced procedure, that shows no need for baking, pray do share wi

We don�t bake between routine washing between soldering cycles. We bake when we immediately go to test or box-build. Certainly, it all depends on your process, materials, and boards. So, how did you determine that you needed to spend the money? I
