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

Thanks Mark and Dave. It sounds like our board design and problem areas are similar to yours, Mark. We talked with our customer about the grid pattern but I'm not sure where we are at with that. In reference to the Tg/Td thread, the material is a

Get over it guys. China isn't going anywhere and it would be too late to do anything about it now even if someone could. It's our own fault for this anyways.......and I mean as consumers. In times when we demand free cell phones, PC's for $100 an

Hi guys. I'm hoping maybe some of you can help me with some information today. I'm looking to find out "ballpark" how much a decent board washer would set me back. The one I currently have just isn't doing the job the way I want it. It seems to have

I'm just looking for some fire-power here. We have a board that when it goes through reflow the first time, everything is fine and has good wetting. When we do the secondary side, one specific part is then Dewetting according to our production oper

A slow profile should get you up to temp unless you have severe mass on your board. 8 zones is a lot oven to work with. There are no lead services that can run your board for you. Might be expensive, but use this cost to justify a real high temp

Hello, I have an oven with a big fail. The Control Unit. It is a 5 zones oven (BTU VIP70)and has more than 10 years, and I think that now is not interesting to repair. I think to buy an offer, an oven Heller of 7 zones + cool,(better for lead free).

Hi, What is the non-leaded part ? the only real obstacle I have found is when using a Leadfree BGA with PB Paste. We have had to do this in the past - the hybrid profile I used was pretty much the same as normal apart from increasing the peak temp
