Solderable Coatings

These proprietary multi-layer systems are designed specifically for use as solderable coatings for glass, ceramic, and infrared substrates.  These films are deposited at less than 200 degrees Celsius which makes them suitable for use on most electronic and infrared optical materials.  In addition solderable coating can also be deposited in a frame pattern around a window that is to be soldered onto a metal package.  These films have demonstrated excellent adhesion, and have survived destructive solder pot and cryogenic testing.
