I think your words are paraphrasing a "last stand" speech by another famous Custer. Let's hope the result is not the same.

We are looking for industry input on solder mask patterns being used with fine ptch BGAs. Undersized mask openings vs. the land/pad, Solder mask defined lands/pads etc. Thank You.

Have you thought about ssd? Boards already have the paste on them when they come in. www.sipad.net

I agree with Jay. The paste will reflow first before the balls. The main reason is the flux content and the dimension of the spheres.

Its a shame no one has input on this. We are in the same spot as you. We have been looking at Filemaker to create our own system.

Why can't you conformally coat the BGA? We do on some of our lines with no adverse affects.

Underfills could improve reliability. If you pick materials right, you could co-cure and underfill and coating.

Try Hi-grade Alloy Corp in Chicago we sell the flux over in the Uk and have several companies using 3541 flux on the Versaflow, works really well no bridging or icicling
