We use TraCon's TraBond 2112 for staking applications where larger gaps are involved. It is formulated for PCB staking applications. The material is very low sag and high viscosity. It's 2part and comes in handy bi-paks. Work life is 20-30min.

I would agree with the above. Epoxy is the way to go. You can have it formulated in different thicknesses and cure times, but you need to watch out for the exothermic heat from the curing.

DevGru: Questions are: * What steps do you recommend taking to "watch out for the exothermic heat from the curing?" * What are typical temperatures for exothermic heat from the curing? * What is the duration of such temperatures? * Do epoxy suppliers

Henkel Loctite makes a hot melt just for this. Do a web search on Loctite Hot Melt and you can see for yourself. Material comes in a variety of ways - we use the 10 inch sticks and their glue guns specially made for the material. Works well, is fa

The hot melt is prob the only way to go for that size gap. If you could decrease that gap I would suggest using 3M Scotchweld DP100FR. Check it out. We use the duo pak cartridges and mix nozzles with the gun. Very simple use and works great in our ES

It's possible that there is limited application of "3M™ XYZ-Axis Electrically Conductive Adhesive Transfer Tape 9719" similar to your intended use. What do 3M™ application types say? Certainly high temperature soldering would make a mess of a piezoc
