Hi Sheila,

        Hope this helps.  We have an SMT process where some connectors are
given a bead of epoxy along the solder joint to give it additional mechanical
strength.  The part then goes through an injection molding process.  Tests
have shown the epoxy adds considerable strength to the joint.

        Let me know if you need more info, and I'll supply what I can.
