Hi all,
I have a couple questions regarding dbl-sided BGA assembly and underfill
...
1) Would the process typically be ...
Reflow Side 1 > Underfill Side 1 > Reflow Side 2 > Underfill Side 2
or
Reflow Side 1 > Reflow Side 2 > Underfill Sides 1 & 2?
2) Do any of you have a recommendation for underfill material(s) that
you use and work well?
Best regards,
