I worked for a EMS who makes Medical Device Electronics, and yeah, the FDA's methodology for validation is a complete cluster-fudge! They did it on the principle of...does the shop air going into your equipment REALLY 80 PSI...or is there REALLY 220

we have a small batch oven. It is does take a long time to cool but we set up an airline that blows in the door when its open and that helped things a lot. looking at the hot plate your thinking about going with, it doesent look like you can program

We are encountering BGA solder open connection. At Functional Test, the board failed. Debug guy diagnosed this BGA open connection (2 locations), by using multimeter. Under 5DX inspection, there is connection. Take the board for localised reflow at

Has the board been looked at under X-Ray? Have you built more than 1 of the boards in question? Do any of the other boards have the same problem? Have you made any changes to the profile between boards? One side of the BGA collapsing during reflow w

We have an outdated Metcal rework station and are thinking about purchasing a new one. We need something that has heat profile capability. We don't really need anything automated, just something that's affordable, durable, and gets the job done. Does

There must be discussions about this on SMTnet but I have yet to find them. I would like to hear from all you smart people about running LF and PB BGA�s on the same board using 63/37 solder. If you run your profile up to peak at around 225C +/- (nitr

Couple of points: * We'll tell ya, although it's tough to tell from these pix, but it does not look like dewetting. It looks like nonwetting. * We don't think you're getting this product hot enough. We don't know where you measured the profile you po
