@geoffkait "The fusible element is comprised of thick film gold that is deposited on
a thermally and electrically insulated substrate. A complete range of
fusing values is achievable by precisely controlling the fusible element
print thickness and geometry. Thick film silver termination pads are
placed at each end of the thick film fusible element. The fusible
element is completely covered with an arc suppressive glass."
That's exactly the material I used to R&D and produce. Beyond the full spectrum of thick film, we also made thin (metallorganic and organometallic) film, gold powders, glass (sounds like a single item, but we had too many formulations to list or discuss here), dielectric tapes, solder, etc. Most fun at work I ever had, and a fair number of us were audiophiles.
Whose thick film did you use, and what means did you use to apply them? Your substrate was alumina or something else?
