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 chec

Generally speaking with most electronic grade epoxies: 1. Cure time is a function of temperature. 2. Polymer bonds begin to quickly break down above certain temperatures (product specific). I believe aprox 170-180C. The strength of the bond de
