Conductive epoxy is good for reworking QFN devices, actually, the only good way to manually place these on a board that is already populated.

Glenn Victor, Oplink
Regarding the uses and applications of conductive epoxies; Is it wise to apply conductive epoxies onto surfaces or components that have materials that oxide very quickly such as copper or even 60/40 solder? What are risks of developing a high resistance at those interfaces. Are there types of conductive epoxies that are more suited to reliably attach to a tinned solder surface vs. others?
