Fred,
     This could explain a number of special units we have built with no
indication of the final use.  These are special Plasma/Silane deposition
units.  Think stainless oven set at 150 degrees C able to do vacuum priming
with flat capacitive stainless plasma generators for precleaning.  let me know
if you want to test this approach.  Bill Moffat

Subject: [mems-talk] Adhesion of metal to epoxy substrates


Dear Collegues,

I am looking for any advice/information on how to improve adhesion of
evaporated metal (nichrome + gold) onto thermo-epoxy based substrates. In
particular, information on chemical and physical (plasma) surface
pre-treatments and/or alternative metals which may have a distinct advantage
over nichrome and gold, would be highly appreciated.

Thanking you in advance,

Fred.
