摘要: An electronic component mounting structure includes a terminal of an electronic component package and a chip heat radiating member. The terminal is soldered on a land of an electronic substrate and the chip heat radiating member is soldered on a back surface of the package. The chip heat radiating member is covered by a packaging resin. The metallic heat radiating pattern integrally includes a pattern extension part that is protruded from the package, such that at least a part of the metallic heat radiating pattern in formed to be larger than the package. The pattern extension part guides excessive solder to outside of the package.

摘要: Air in a thermally insulated space, which has been expanded by heat resulting from heating treatment for curing a thermosetting potting material, is prevented from entering the potting material. A casing has a partition wall that partitions an opening into a heat-generating-electronic-component placement section, where a heat generating electronic component is placed, and an adjacent section that is adjacent to the heat-generating-electronic-component placement section, when a heat releasing member is fixed to the opening. The heat-generating-electronic-component placement section is filled with a thermosetting potting material for moisture prevention up to a height which allows at least the heat generating electronic component to be buried in the potting material. The adjacent section has in the casing a communicating portion that communicates with a position which is apart from the heat-generating-electronic-component placement section filled with the potting material.
