Title:
ELECTRONIC DEVICE PROVIDED WITH ELECTRICAL ELEMENT AND TEMPERATURE DETECTOR
Document Type and Number:
WIPO Patent Application WO/2015/107892
Kind Code:
A1
Abstract:
The lower surface of a substrate is exposed from a sealing resin of this electronic device. A heat spreader, which is a heat dissipation material, is bonded to a surface of the substrate, said surface being on the reverse side of the lower surface (and hereinafter referred to as the upper surface), by means of an adhesive sheet, which is an adhesive material. This heat spreader functions as a base together with the substrate and supports a power transistor. The power transistor, which is an electrical element, and the heat spreader are bonded with each other by means of an adhesive sheet at a surface that is on the reverse side of the bonding surface between the heat spreader and the substrate. A bus bar, which is a power supply plate, and the power transistor are bonded with each other by means of an adhesive sheet at a surface that is on the reverse side of the bonding surface between the power transistor and the heat spreader. A thermistor, which is a temperature detector, is connected to a lead, which is a conduction line, and is disposed on the upper surface side of the substrate.
