Abstract:
The present disclosure relates to a ring-frame power package that includes a thermal carrier, a spacer ring residing on the thermal carrier, and a ring structure residing on the spacer ring. The ring structure includes a ring body and a number of interconnect tabs that protrude from an outer periphery of the ring body. Herein, a portion of the carrier surface of the thermal carrier is exposed through an interior opening of the spacer ring and an interior opening of the ring body. The spacer ring is not electronically conductive and prevents the interconnect tabs from electrically coupling to the thermal carrier. Each interconnect tab includes a top plated area and a bottom plated area, which is electrically coupled to the top plated area.
