Electronic assembly for an inverter

摘要

An electronic assembly for an inverter comprises a substrate having a dielectric layer and metallic circuit traces. A plurality of terminals are arranged for connection to a direct current source. A first semiconductor and a second semiconductor are coupled together between the terminals of the direct current source. A primary metallic island (e.g., strip) is located in a primary zone between the first semiconductor and the second semiconductor. The primary metallic island has a greater height or thickness than the metallic circuit traces. The primary metallic island provides a heat sink to radiate heat.

1. An electronic assembly for an inverter, the electronic assembly comprising:
a substrate having a dielectric layer and metallic circuit traces; a plurality of input terminals for connection to a direct current source; a first semiconductor and a second semiconductor mounted on the substrate and electrically coupled together between the input terminals; a plurality of surface mount connectors mounted on the substrate that are electrically connected to a respective one or more of the metallic circuit traces, the input terminals terminating in ones of the surface mount connectors; a primary metallic island mounted on the substrate and located in a primary zone between the first semiconductor and the second semiconductor, the primary metallic island being separate from the first semiconductor and the second semiconductor, the primary metallic island having a greater height or thickness than the metallic circuit traces, the primary metallic island providing a heat sink to radiate heat; and a secondary metallic island mounted on the substrate and located in a secondary zone between adjacent ones of the surface mount connectors, and the secondary metallic island being separate from each of the surface mount connectors.
