Abstract

Abstract A heat sink for a rectifier comprises two heat sink plates, six nail connectors and six diodes. Six diodes are formed by with packaging six dice during the heat sink manufacturing process so that the six diodes are completely embedded into six holes. Therefore, the heat generated by rectifying AC power to DC power may be well distributed around the main body of the heat sink to avoid water infiltration and particle contamination. The attachment between diodes and heat sink may be enforced.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 87 words
A heat sink for a rectifier having first and second heat sink plates being engaged with each other, each heat sink plate including a plurality of holes formed thereon and each hole having a flat bottom, a copper plate located on said flat bottom, a diode dice positioned directly above said copper plate, and a nail connector attached to said diode dice, wherein said diode dice is completely embedded in said hole and packaged as a diode at the same time as said heat sink is manufactured.
Claim 2
Dependent Claim 87 words
A heat sink for a rectifier having first and second heat sink plates being engaged with each other, each heat sink plate including a plurality of holes formed thereon and each hole having a flat bottom, a copper plate located on said flat bottom, a diode dice positioned directly above said copper plate, and a nail connector attached to said diode dice, wherein said diode dice is completely embedded in said hole and packaged as a diode at the same time as said heat sink is manufactured.
Claim 3
Dependent Claim 86 words
A heat sink for a rectifier having first and second heat sink plates being engaged with each other, each heat sink plate including a plurality of holes formed thereon and each hole having a flat bottom processed with silver or nickel electroplating, a diode dice positioned directly above said electroplated flat bottom, and a nail connector attached to said diode dice, wherein said diode dice is completely embedded in said hole and packaged as a diode at the same time as said heat sink is manufactured.
