QA Error #0 The strange part is that if I reprogram the Pickup over and over again, using the same variables, eventually the error goes away and does not return for that particular pickup. However it will occur again for subsequent pickups. Has

We are looking at doing gauge R&R studies on our placement equipment. I know that IPC9850 cites the test vehicles and test parameters. One thing that we are not clear on is what gets used for an external measurement device. Any input would be greatl

There are also No-Clean/No-Residue fluxes where the flux gets eliminated by the heat of the soldering process (this eliminates “does not look pretty” in hegemon’s post). Patrick http://www.interfluxusa.com
