Electronic substrate assembly structure for use in vehicle electronic device, has water proof seal inserted in connection section and sealed by connecting screw, where electronic substrate is adhered by water proof seal

摘要

The structure has a ground plate part (2) provided with a heat transfer section. A cut-protection section forms a gap between an opposite side upper surface and two heat transfer models, where the gap is filled with thermal conductive adhesive. A connection section includes a covering part (1) and the ground plate part, and a water proof seal is inserted in the connection section and sealed by a connecting screw (3). An electronic substrate (5) is adhered in a sandwich manner by the water proof seal. The seal and adhesive are selected from a fluid silicon resin material.
