Where are you measuring your temperature at? Are you measuring pad/ball interface temp through a hole in the board, or a lead on a different part, or board surface, or.....?

Are you sure the BGA is not Leadfree and the proces you are using is a leaded process? If so then the Balls will not reflow and there will be cracking. Likewise the other way around

So if you are getting 100% consignment parts on a single sided board, then you are doing it all for free and getting 3-dollars for a doubled board? Wow, that is pretty cheap.

Hi Jerry, I bet you have dross build up on your wave. Are you running nitrogen? If not this could be the case. Hope this helps!

Just as I thought earlier, you have a stagnant wave. You should be able to mechanically adjust it so it flows in the same direction of your boards.

Jerry, In your initial post you give 260C as solder pot temp if you�re not using lead-free I would reduce the temp to 250C this will also reduce oxidation rate.

Dave, There is not really a �smart� or scientific way to check this but I know of easy ways and very effective ways. Fex. an easy way to check is with a 3� spatula, you hold the spatula at the same angle as the board and drag trough the wave simula
