Barry, We do not see much in the way of solder splatter or solder balling. We have removed some parts but in the process of doing so we remove any useful evidence really. Quite a lot of the solderable portion of the part is on the underside. Like

Had the very same thing happen the first time we used the small QFNs. The aperture for the thermal pad in the center needs to be cut in a grid form, either squares (with around a 10 mil spacing between openings) or circles, like a BGA pattern. Too mu

So the moral of the story is..... these SAC305 BGA's were accidentally mixed in with a Leaded process, the profile couldn't get hot enough due to Tg and Td constraints on a known good QFP on the same board, and consequently, the whole assembly fail

Boy it is good to see the wave master back in action! I mean really guys, is Larry the only one here who knows that the lead turns into vapor in the oven and then in the cooling zones it falls back onto the board and creates the solder joints? P.

Craig- Pretty much every equipment vendor is guilty of what Assembleon did to you. When they think you are committed to their platform OR you are small potatoes to them.....they will hammer you on pricing. It's always been that way and they all do i
