Please note that pin holes and blow holes are not always defects. The latest IPC 610A Rev D workmanship standard has them as process indicators- depending on Class. I don't have the document handly while writing this. It would be good to look that up

You havn't compared bills. What makes you guys think you need more heat to remelt solder than it gave off solidifing? And don't confuse power and energy. Yes it takes more power to melt solder but for a shorter time. Where do you think the break e

So Stephen, I don't know what part of the country you're from, but during summer time, what DO you do with your air conditioning at home? "Your wrong" is a very general statement, without a "right" statement to counterpoint my wrong statement. Hon

I agree with Sr. and Doug. Capable equipment will run like sh^t if the process is not in control. Number one, don't be scard of BGAs. They are pretty easy if done in control and will cause you less pain than you ever thought. X-Ray is your best i

I agree. The only way to make them care is to show them how it effects their pocket book. If you don't charge them they will continue not caring. If you do charge them you risk hurting their feelings and making them look bad in front of their bosses

Completely agreed. That is what the DFM is for. It gives you, the contract manufacturer, the opportunity to describe what you find to be the trouble areas for manufacturability. Given that, you are able to make them acknowledge that if they choose

Point is lead free is a fact for many of us, whether we like it or not. We can all agree upon the fact that it is forced upon us for the wrong reasons. Doesn't change the fact that The majority of our colleagues in Europe and Asia have to make this w

I think this depends on what you are reporting as defects... I would place my inspection first, team up my Touch-up/Rework into one category. If for any reason I need to hit a joint after leaving my oven, that to me is classified as a defect and s

I agree the longer soak will help provided you are not applying to much heat/time to the board now. -are the pads that lift connected to anything? This has happened to me in the past where un-connected pads would come of far easier than those connec

Thank you for the links. I didn't know that there are companys that build test systems for ultrasonic inspection. My idea was to use a ultrasonic detector similar to crack inspection, for example to detect if the cooling pad is melted, or a solder jo
