Hi I have seen some of our multilayer PCBs are having delamination issues even after baking them in the ovens. Does anybody faced this issue before? The problem occured after reflow process and wave solder process as well. The temp profiles are well

Ken, we always build the bottom side of the board first. That also insures that there isn't any problems with the actives being reflowed and falling off in the glues curing process. By the way we do both paste and glue on the bottom of the boards t

we have been doing reflow on SLX PCBs and found out that when lidding, the components have been shifting. Has anyone been doing low temp lidding on SLX PCBs using the flowstar 4036 soldering system? If so, what low temp solder was used and profile

Does anyone have knowledge or experience with Pin & Paste on boards that are .095" thick? The boards would have mixed technology, PTH, fine pitch, and BGAs. I did a search for this info and nothing touches on this particular subject, thicker boards.

Dear Jack, If you are trying to attach a connector - contact me offline or go to http://www.tekais.com. Teka offers a technology that deposits enoough solder volume on connectors for thicker PCB's.

How many % were affected? If a few,it can be caused bcoz of PCB coating. We had encountered it and PCB house replaced for faulty boards. Since then, we do test first if we hve to solder PCBs from this PCB house.
