Long term reliability indeed is the issue, depending on environmental conditions this type of connection (in my experience) is prone to failure. A lot depends on the epoxy being used. Some are more aggressive (i.e.. Epotek H20E) and may work for the application but still not recommended.

Subject: [TN] SOLDER/EPOXY REACTION
I have a customer who is trying to attach our SMT part to their hybrid
assembly using silver fill epoxy. We use a lead free alloy (Sn 96.5/Ag
3.5).
Any body have any experiences in this area. The customer (actually the CM)
is worried about dissimilar metals and long term reliability, should they?
Thanks,
Dan
