In thirty years of Electronic service I have never had problems with moisture in boards when hand soldered. I have worked on boards in boxes for defense through industrial control, joy rides etc. Sometimes they some back buried in half an inch of dus

I think I have the vision problems figured out. There were two problems. 1) The Alignment type was set to "Small" for my TQFP48 part. It should have been set to "Complete". This is a clear case of poor documentation. The AutoProgram manual lists the

We have inline reworkers, so this time has been factored in. We currently use Siemens S25/20 machines with M1 systems. The placement machines run a little slower than the AOI at times so there is time to perform review, most of the time. It's not

"Do you think these machines are less appropriate for smaller lot sizes and PCB's with just a few through hole parts?" That depends. It will still save time if your lot sizes are small, as opposed to hand placement. I would not recommend buying an

UIC still manufacturers new thru-hole machines. Both axial and radial insertion models are available. They stopped making the multi-mod dip inserters in '91 or '92. And parts are easily acquired for any older models, there were a ton of machines out

As far as OEMs go, Universal themselves are pretty reasonable about second-user support. Its only $500 to register an older GSM, and their factory field service people aren't any more expensive than many competent smaller companies. You do have to bu
