Abstract
An insulated metal substrate (IMS) includes a metal substrate, an insulating layer, a plastic frame, and a plurality of conductive metal pads. The insulating layer is located on the metal substrate. The plastic frame is located on the insulating layer and has a plurality of aperture areas. The conductive metal pads are located on the insulating layer and are respectively located in the aperture areas, and the conductive metal pads have sidewalls are in contact with the plastic frame.
Claims9
A method of manufacturing an insulated metal substrate, comprising:
- forming a plastic frame, wherein the plastic frame has a plurality of aperture areas, and the plastic frame comprises epoxy resin:
- stamping a metal material to form a plurality of conductive metal pads;
- pressing the conductive metal pads respectively into the aperture areas of the plastic frame, such that sidewalls of the conductive metal pads are in contact with the plastic frame, and a sheet-like structure including the conductive metal pads and the plastic frame is formed;
- and disposing the plastic frame and the conductive metal pads on an insulating layer of a metal substrate comprising copper, such that an entire bottom surface of the sheet-like structure is in contact with the insulating layer, and a vertical projection of the sheet-like structure on the metal substrate entirely overlaps the insulating layer of the metal substrate, wherein the metal substrate comprises a plurality of heat dissipating structures on a surface of the metal substrate facing away from the insulating layer, and the heat dissipating structures are arranged at intervals equidistantly.
