Electronic control apparatus for vehicle using overmolding and manufacturing method thereof

A method of manufacturing an electronic control apparatus for a vehicle, comprising:

• coupling a printed circuit board (PCB) including an electronic control substrate configured to electrically controlling the electronic control apparatus of the vehicle and at least one heating element positioned on a surface of the electronic control substrate to a connector including a connector pin;
• attaching at least one heat radiating plate onto an opposite side of the surface of the electronic control substrate where the at least one heating element is positioned;
• inserting the PCB, to which the at least one heat radiating plate is attached, into upper and lower molds;
• injecting mold resin;
• and
• overmolding the at least one heating element, the PCB, and an outer portion of the at least one heating radiating plate such that heat generated from the at least one heating element is directly discharged to air through the at least one heat radiating plate positioned on the opposite side of the surface of the electronic control substrate where the at least one heating element is positioned,
• wherein the at least one heat radiating plate has a size corresponding to a size of the at least one heating element.
