TL;DR: In this article, an electronic control unit (10) mounted in a vehicle engine compartment, having a plastic case body ( 14), metal collars ( 32 ) each molded into the plastic case, a metal base ( 12 ) having bolt through-holes ( 28 ) prepared in the same number of the metal collARS such that a bolt passes through each metal collar and one of the holes corresponding thereto, and a heat-generating component (18 ) mounted on the base.

Abstract: A fastening member for an electronic circuit board having an elastically deformable leg formed in a case for housing the electronic circuit board and a projection formed continuous with the leg to be engaged with the electronic circuit board so as to fasten the electronic circuit board on a prescribed mounting surface in the case. In the member, the projection is engaged with the electronic circuit board such that a prescribed angle is formed between a surface of the projection contacting the electronic circuit board, when the electronic circuit board is fastened on the mounting surface in the case. With this, since the tangent between the board contact surface and the electronic circuit board is variable within the range of the board contact surface, molding error can be tolerated (absorbed) and volumetric variation produced by temperature change can be readily coped with.

TL;DR: In this article, the case body is inverted and placed over a rising coating bath, and then the coating bath is raised close to the opening edge such that the board is dipped in the coating liquid and is coated.

TL;DR: In this paper, the problem of providing a fixing member for an electronic circuit board, which is capable of allowing a molding error and coping with a stress caused by a volume change due to a temperature change or vibrations, is addressed.
