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.

A noise suppression circuit board design to provide a power supply to an inductive heating element is disclosed. The noise suppression circuit provides a configuration for a multi-layer circuit board that has radiation noise emissions below the CISPR 11 (limits and methods of measurements of radio disturbance characteristics of industrial, scientific and medical (ISM) radio-frequency equipment) thresholds in the 30 MHz to 1 GHz frequency range.
Abstract:
A composite heat sink with improved mechanical strength and thermal conductivity can be made using a printed circuit board with machined recesses on the back side. The printed circuit board is mated to a heat sink with surface features that match the machined side of the printed circuit board. A thin layer of thermally conductive material such as a gap filler pad, thermal grease, thermal gel, thermal epoxy or the like may be added between the printed circuit board and the heat sink prior to joining them together. Mechanical attachments such as screws, rivets and snap features may be used to form the printed circuit board and the heat sink into a single composite structure.The machined recesses in the printed circuit board are machined from the areas under and near surface mount components that generate a significant amount of heat. This reduces the thickness of printed circuit board material under the surface mount components and significantly improves thermal conduction.
