Im sure you will get some better responses but here is a start. We went from UP2000 to UP3000 Ultraflex about 2 years ago. The UP-2000 uses tooling nests and UP-3000 Ultraflex does not. Makes a huge difference in setup time. Up-3000 is BIG. I think t

Thanks for the help but I do have another question. First I guess that just the touching of the smock to the skin is anough to give the charge on the person a path to the smock. OK I can accept that if button up at the breast and sleeves. Now I kno

Brian, We had similar problem in our inline wash machine time ago. We checked everythin on equipment (filters, DI water purity, sprayers angle, etc). To make the long story short, we found out that the problem was caused by a new solder paste. This s

Dominic, I guess it would depend on criticality and volume. We do mostly low volume builds here, and the only time I do a solderability test is when we encounter an issue during production. That process works for us, considering the volume of the

Patrick, Back in my rich OEM days, i actually DID measure mg/in^2. I bought a scale, which measured in mg, specifically for this. Basically, took a blank PCB, took a "before" weight, sprayed it, and then took an "after" weight. I measured at diffe

I have zero experience with SN100c, but hey, how much different can it be from Sn63Pb37?! We solder large connectors all the time - sometimes these connectors reside on a ground plane area. We've been able to overcome hole fill issues (on 63/37) th

When you teach the "teach boardstop Y" make sure the camera is seeing the leading edge of the board and not too close to the rails. It should calculate the pre-stop position correctly. I assume you have thoroughly checked the sensor. Also check th

I am seeing allot of issues with SOD-323's in our Heller Oven. The parts seem to move or blow off their pads. We do have all the fan speeds on low and still having this issue. The parts are sitting in the paste not on top, so there is some force o

Ben, I'm not aware of any 'automatic' method to convert PTH footprints to SMT. Typically, many of the components are passives, and there may be a way in your CAD software to change the passives of a common size to a different footprint. That will co

Stephen, This is a board designed for medical apparatus and we're needing to change 3000 placements, it's about 2000 different parts. Some boards have about 90 parts and some have greater amount. Impedence of the board happens to be a great issue
