ELECTRONIC CONTROL APPARATUS FOR VEHICLE USING OVERMOLDING AND MANUFACTURING METHOD THEREOF

摘要

The present disclosures provides an electronic control apparatus for a vehicle using overmolding in which a heat radiating plate is attached to an opposite side of a part requiring heat radiation in a printed circuit board (PCB) and a part other than the part, to which the heat radiating plate is attached, is overmolded so as to directly discharge heat to the air through the heat radiating plate such that a heat radiation effect is excellent, the heat radiating plate is attached in advance and then a housing is formed of mold resin such that a manufacturing process is simplified, and a printed circuit board (PCB) is surrounded by mold resin such that a waterproof function is excellent, and a manufacturing method thereof.

主权项

1. An electronic control apparatus for a vehicle, comprising:
a printed circuit board (PCB) including an electronic control substrate configured to electrically control each part of the vehicle, and electronic components positioned on one surface of the electronic control substrate; a heat radiating plate attached to the other surface part of the electronic control substrate opposite to the one surface part, on which the electronic components are positioned, for heat radiation of the electronic components; a connector including a connector pin, and coupled to the PCB; and an overmold housing configured to overmold the PCB, to which the heat radiating plate is attached, with mold resin, in such a manner that the remaining parts of the other surface of the electronic control substrate other than the other surface part, to which the heat radiating plate is attached, are overmolded.
