[Robotgroup] advice needed: soldering Piezo disks

[Andre Lamothe]

Hmmm, in general, you want to do it quickly and get the solder to flow fast, 
so tin the lead itself, put some flux on the surface and then wet the solder 
tip with solder and then solder it down dead center. That usually works 
pretty well.

Has anyone had experience in soldering leads to piezo elements
(crystal layer with brass backing)?

Soldering a lead to the brass seems pretty straightforward.  Any tips
on soldering the other lead to the piezo crystal layer itself?  The
crystal layer appears to be epoxied to the brass backing plate.  How
likely is that to be damaged?

I have examined pre-soldered piezo elements but I cannot tell what
preparation was made to the crystal layer before soldering the lead
to it.

Thanks for any tips y'all might offer.
