Has anybody ever done a double-sided reflow with a Altera 240-pin RQFP on the bottom? The part has a heatsink in the top and weighs just over a half-ounce... Thanks in advance! -Steve Gregory-

Russ, we had similiar issue on the corner seperation. The board is ENIG and the part is Altera FBGA 1020 (Super BGA) and reflowed by tin/lead paste. Please comment your concern on Altera parts! Is CTE mismatch?

We are having some difficulty soldering a 240 pin Altera device. We use Alpha WS-609, a very generic profile for that solder paste, and a 6 mil stencil with laser cut apertures (1:1 ratio). This is a 20 mil pitch device (aperture size is 10 mils X 75
