Abstract
An improved ceramic substrate for supporting, cooling and interconnecting components on both surfaces of a substrate includes a plurality of coolant carrying channels separated by fins and extending through the substrate generally parallel to the surfaces of the substrate; and a plurality of routed vias for interconnecting component terminations on opposite surfaces of the substrate which are not aligned with each other and with a fin; each routed via includes an internal via extending through a fin and a surface blind via extending inwardly from each surface, and at least one transverse segment interconnecting one end of the internal via to one of the surface blind vias.
Claims6
An improved ceramic substrate for supporting, cooling and interconnecting components disposed on opposite surfaces of the substrate, comprising:
- a plurality of coolant carrying channels separated by fins and enclosed within the interior of said substrate between the components on opposite surfaces and extending through said substrate generally parallel to said surfaces of said substrate;
- and
- a plurality of routed vias for interconnecting said components disposed on opposite surfaces of the substrate by component terminations which are not aligned with each other and with a fin, each said routed via including an internal via extending through a fin, a surface blind via extending inwardly from each surface, and at least one transverse segment interconnecting one end of said internal via to one of said surface blind vias.
