We just went through a similar issue with our MY12E. Make sure your Midas vacuum system is working, check your Midas Z friction. Also verify the Centering unit centering band. You can swap your MOTZ and MOTC to rule out the card. The tool install t

Dason, IPC/EIA J-STD-001C states: "....temperature within the range of 230C (446F) to 290C (554C)." That's a pretty wide process range. 250C has been typical in the past. We run ours from 230C to 240C. We have found that some single-sided PCBs can de

Well, here I am working Saturday. Seems my production Supervisor had the nerve to get sick on an overtime weekend and, for some peculiar reason, the execs expect the numbers to be met anyway. Go figure! Let me backtrack and clarify that it was th

The "band wagon" was a corporate decision. The performance issue concerned a communications problem between the line computer and the F5 (f5 locked up in the middle of a PCB). This issue did not show it's ugly head until a month after install. I t

actually the "yellow lite" part of my posting was simply spoofing Dave's light up band-aid wrappers. But seriously (again) most high temperature Kapton polyimide film tapes, like 3M #92 and #1205, develop a considerable charge when unrolled or remov

Amazing in today's technology that people still bake because "that's the way we've alawys done it". Baking is a band aid for poor manufacturing of the PCB. Moisture can become trapped between the layers during buildup. This moisture when it contacts
