PROCESS FOR BRAZING METALLIZED COMPONENTS TO CERAMIC SUBSTRATES

摘要

A process for brazing a metallized component to a metallized ceramic-based substrate comprising the steps of: a) applying a second conductor composition over the metallizations on the substrate such that the metallizations are covered by said second conductor composition which consists essentially of a metal powder and an organic medium; b) drying said second conductor composition; c) firing said second conductor composition at a temperature sufficient to sinter the metal powder of the second conductor composition and drive off said organic medium thereby forming a second metallization layer; d) forming an assembly by positioning at least one metallized component on said second metallization layer and a brazing composition at the component-second metallization layer interface; and e) heating said assembly at a temperature sufficient for said brazing composition to form a joint between said component and said second metallization layer.
