Ted-
We do repair on PTFE boards on occasion - I don't know what adhesive
we use but we do use TetraEtch from W.L. Gore to prepare the bonding
surface. TetraEtch contains HF acid which is no fun to use but the
resulting bonding surface is very robust.

Occasionally with Teflon base material boards adhesion of a pad or run
is lost during assembly, especially with connectors and larger parts which
require more heat, and we are wondering if anyone has experience in rework
or repair to reattach pads or runs to Teflon boards. We would like bond
strength in the range of original and without microwave performance
degradation. Anybody got any ideas or suggestions?
Thanks
