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?

Ina ddition to the above it can be from CTE mismatch and the joints are breaking during cooling. Is this an Altera part?

I am looking at placing a Altera BGA device that has a .45mm Nominal Ball Dia. with a .8 spacing c-c between balls. The PCB will be gold plated so co-planarity should not be an issue. Interested in suggestions that may assist producability when pla

Most suppliers provide this information on their parts. For example http://www.altera.com/literature/an/an114.pdf We have no relationship, nor receive benefit from the company referenced above.

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

Hi Russ! An "R" QFP is what Altera calls their Plastic Quad Flatpacks that have a heatsink in the top...they actually call them Power Quad Flatpacks. I'm familiar with the formula, of how one can figure out if there's enough surface tension for a p
