Re:Diff. Epoxy resin (ER) conformal coating Vs ER adhesive bonding matrl | 4 October, 2000

Hi folks,

What are the differences between Epoxy resin(ER)conformal coating and adhesive stacking/bonding material? My PSA/PRA (Post solder/reflow assembly)bracket assembly process got some ER adhesive encroachment on pads/solderjoints. I have checked CTE, epoxy resin -polymer crystallization, rheology, electrical properties/parameters...(some of the units are not similar at all!)- - Appreciate any kinda help -.

Thanks in advance Regards Kc.
