Material Notes:
Typical Powder Form: DSD Zinc-Boro-Silicate passivation glasses are used for hermetic passivation of high voltage diodes, thyristors, and transistors. They provide high junction temperatures and can be applied to wafers using thick film and electrophoresis methods. These products are formulated and produced to achieve low alkali and iron levels. These glasses are also used for encapsulation of rectifiers using glass beading application methods.Information provided by Ferro Corporation
