SWAG - Was your experiment on the board with the large ground plane? The board we are seeing issues with also has a large ground plane (approx 50% of PCB), and 90% of the delamination occurs in that area. The delamination is about the size of a sil

I love this!!! Two whizzettes with the same information and they spin-off in two different directions. Gad this is great!!! Delamination is a pretty broad topic, but that you have a problem with two suppliers makes me think the delamination is cau

50% chance his boss has heard of (or maybe even one time seen) delamination and wants to be sure they don't have that problem. His boss probably felt a need to specify a test and that was one he had heard of. Personally I would recomend find a way f

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

Since the implementation of the ROHS process in our Company with the higher temp requirements, we had observed an increase in problems related to delamination in the PCB's. Actually we are using FR408 and Gracescore materials and are changing to a Ve

Talking about delamination...... I have a customer requesting info about the max temperature ratings for FR4. Can anyone point me to a good source? ( and yes, I HAVE checked the archives, to no avail.....) Phil

Anybody know a good source to refer to for possible problems with Ti-Al reaction and what could lead to delamination at the base of a via?

I thought Dan saw the delamination after wash - not baking? What temp are your dryers on the washer set at?

First, we have talked about drying / baking / demoisturizing / whatevering bare board previously. Search the fine SMTnet Archives to get started on recipes. Second and more importantly, you gotta fix this delamination problem. If it is delaminatio

MSL 3) By SAM (Scanning Acoustic Microscope) before to remove them from PCB, you could identify if de-laminated or not and the degree of delamination. Best Regards...GS
