We all know those academic 'reliability studies' are very focused and only give a snapshot of real life. The real reliability studies of leadfree are starting as we scramble to meet our numbers. We have no idea about your customers' expectations ab

I certainly would not buy off any product from a manufacturer that is for sale. Imagine they have known they were going to do this for some time now and all of the cost cutting and apathy that is occuring at this time does not bode well for their cus

Yes, this board is approx. 3" x 17" x .062"T with large areas of ground planes. However, the delam. does not seem to be confined to the plane. We also see it around component pads and fiducials. Generally speaking, it could be said that the first

SWAG - I also forgot to mention a few things. Our delmaination was always between the large copper plane and the laminate. It is a multi-layered board, so even when the delamination appeared around components (through visual inspection), cross-sect

Patrick, Have you seen Al Gore's documentary on Global Warming, "The Inconvenient Truth?" It was okay, but I didn't like how Gore got political in a few scenes by slamming the current administration's environmental policies (or lack thereof...c'mo

Some production problems we've faced: 1) Delamination; 2) Reflow fixture distortion; 3) Obsolete parts; 4) Failure of blower motor bearings in older reflow ovens; 5) Poor toe fillets with miniSOTs on thicker PCB's; 6) Lack of updated component data s
