Solderable Coatings

Description

These proprietary multi-layer systems are designed specifically for use as a solderable coating 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 coatings 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 solderpot and cryogenic testing. See Solderable Coatings case studies for details.
