ABSTRACT
Disclosed is a heat dissipator for electronic components on a
ceramic substrate. The ceramic plate receives heat from the component at one sur-
face and has a plurality of separate spaced metallic heat-conducting elements
mounted on and extending from the other surface of the plate In a preferred
embodiment the ceramic plate on which the metallic elements are mounted is
separate from a ceramic substrate on which the electronic components are
mounted; the ceramic plate carrying the metallic elements includes adhesive
for adhering it to the ceramic substrate carrying the electronic components;
the metallic elements are cylindrical copper pins; and the pins are connected
to the ceramic plate via solder and metallic pads deposited on the ceramic
plate.
