Active metal brazing
WebDissimilar vacuum brazing is an alternative approach to obtaining a metal-ceramic joint. With the selection of appropriate active filler metal, the molten braze melt can wet and … AMB consists of a metal foil soldered to the ceramic baseplate using solder paste and high temperature (800 °C – 1000 °C) under vacuum. Although AMB is electrically very similar to DBC, it is typically suited for small production lots due to the unique process requirements.
