MANUFACTURING METHOD OF ELECTRONIC CONTROL UNIT, CONNECTOR AND ELECTRONIC CONTROL UNIT MANUFACTURED BY THE MANUFACTURING METHOD OF THE ELECTRONIC CONTROL UNIT

摘要

PROBLEM TO BE SOLVED: To reduce stress generated at the soldered part of a wiring board and terminals due to the warp of the wiring board housed inside a case body. SOLUTION: The manufacturing method of the electronic control unit 100 provided with the wiring board 2 where an electronic component 3 is mounted, a connector 4 including the plurality of terminals 41 and a housing 42, for which the terminals 41 are to be soldered on the wiring board 2, and a case body 5 for holding the wiring board 2 particularly includes a first step of soldering the respective terminals 41 of the connector 4 onto the wiring board 2 and a second step of housing the wiring board 2 and the plurality of connectors 4 integrated by the soldering inside the case body 5. In the first process, the terminals 41 and the wiring board 2 are soldered while applying loads for preventing the warp of the wiring board 2 to the wiring board 2. In the second step, the wiring board 2 is held by the case body 5 in the state of restraining the wiring board 2 so as to correct the warp. COPYRIGHT: (C)2009,JPO&INPIT
