Cross: IPC nor anyone else calls out recommended pressures for washers used to clean circuit boards. IPC and the other standards setting folk are in the business of defining the expected results or outputs of processes or acceptance criterion. They

We use MyData direct up here in the New England. Always seemed easiest to me. In a previous life, I did use an independent contractor. She used to work at MyData and serviced my machines in an even more previous life. Then branched out on her own

I'd say it all depends on the CM, and how they cost out their production floor. I've seen everything from a flat cost per component placement (something like .05/machine placed smt part, .15/machine placed tht part, .25/hand placed tht part) to stra

I once worked at a small CM that did this. On the floor we would save the spent tape to be re-used, so the only recurring costs would be the cover tape. Unless it was otherwise damaged the carrier tape was good for a few passes at least. It just h

This is strange EPA is not out to fine companies but to enforce regulations. We are in the solder and flux business and get audits at least twice a year. We are not perfect (yet) so there are times that we have non compliances. When that happens we g
