Depends on the programming that needs to be done - there is free software available such as GERBV - 'http://gerbv.geda-project.org/' but not that easy to use. For comparing BOM's there is some free software called MELD - http://meldmerge.org/ that's

We do use a company for custom fixtures, but we also make some in house. The biggest hurdle for a board that requires a fixture to go through printing and SMT is that the board has to be the tallest thing. So any hold downs or locating hardware has

OK, thanks for access a few decades ago when I was a kid, I printed soldermask and legend inks on circuit boards. Printing solder mask, (PC-401, SR1000, LPI) I would use SM-1000 stencil material on 86 or 110 mesh I've been trying to find sm-1000 bu

Lab tests can confirm the composition of your material. I'm going with tin oxide. Tin oxide changes color depending on the thickness of the deposit. Your deposit is fairly thin. It will change to a brown color as the thickness increases. Your EDX

Try a liquid latex masking material. Youll most likely have to cover the hole with kapton, really drench the thing in the liquid latex to prevent the ultrasonic from damaging it then bake it at 50-70c for about 2-4 hours. With no bake its usually a 2

I believe usually board shops will have scrap pieces laying around and will send you some if you ask. I've also seen them use scrap material to sandwich production boards for shipment to protect them. And we usually get scrap boards for testing and h

The impact of course is a lot less for newer PnP, but for older machine there might be different story. What if the bad marks not being read correctly? The result would be "good" board being skipped, while "X-out" being loaded. That would waste mu
