What is the highest temperature set at in your oven and your belt speed. Also what type of oven do you have? Thanks much. Your right about alot of heat needed. We actually see the outside balls much flatter and soldered compared to the middle bal

This is caused by cte mis-match. The balls in the corners are short and fat. The balls near the null point are tall and more normalized. I don't remember what the zone settings were... BTU VIP98 BS was probably 22-25 IPM

I think I would work on the reflow profile or your paste handling procedures to prevent the splattering. I might even change paste suppliers or formulations.

We are using AIM WS300 solder paste and are experiencing excessive voiding on our BGAs. We have exhausted reflow profile alternatives and just can't beat the voids. Has anyone had success with this paste on BGAs? If so how?

Perhaps I read your question wrong, but I would be more inclined to look for changes in your solder paste, your screen printing process, and your reflow profiles if you're suddenly having problems with more than one component.

Hi guys.. I just want to know on what are common types of terminal plating on chip capasitor and does each plating will affect reflow profile? Thank..

Does anyone know of any tests or testing done on the peel strength of components to pads. I have alot of info on FAB level peel strength testing, but nothing on components themselves. Is there any process(es) to test and insure new pastes and reflo

I have heard that with lead free soldering, the cooldown phase is NOT as critical as it is for Tin-Lead. -2�C per second cooldown is good enough to form a good solder joint with good grain structure.

Thanks Pete, I have plenty of Omega thermocouple leads on hand. By the way ECD is the mfg asking $989 for a probe that costs about $100, to which they add a pcb edge clamp.
