Is there any problem with soldering BGA package on FR-4 maetial. does Tg of laminate may disturb the laminate proprties.?
Actually we are designing PCB for BGA-676 pin package. The question is does FR-4 material serve the purpose or we should change material to FR-5 or polymide or some different material.
The majority of boards are produced from FR4, I have done BGA designs for over 7 years and never used anything but FR4. Plenty of life left in FR4 yet. If you are using a lead free process I would look at a decent FR4, i.e. Tg of 170
it also works upto the low GHz's
Soldering profiles for BGA aren't different from other SMD components. The name "FR4" doesn't exactly specify the temperature behaviour, you should have laminate suited for leadless soldering, assuming you have it.
