Epoxy is used because it is so durable. This means that any removal
techniques are going to be equally aggressive, Thermal shock, thermal shock
with mechanical shock, powerful solvents, acid sprays, abrasive wands and so
on. From your description of assembly it sounds as though you will be at
grave risk of damaging the bits you are trying to save.
I would start by asking 3M then work your way out from there.

Good luck

Subject: [TN] Removing epoxy adhesive 2216

Hi all,

We have to salvage 2 15-pin Micro-D connectors from a flex board, to use on
a new board. The de-soldering can be achieved, but they are also bonded with
3M(tm) Scotch-Weld(tm) Epoxy Adhesive 2216, and this is pretty strong stuff.
Our tech is very skilled, but has concerns about damaging the connector
(Glenair GMR7580C-15S2EB-429F), as this is for space application. These are
long lead parts, so doing this is undesirable, but a last resort. Do any of
you have suggestions for removing this adhesive? Thanks in advance for you
help!

Howard A. Watson
