本発明は、自動車制御装置に係り、特にエンジン室実装
に好適な耐振性、基板の反り１位置ずれ等に優れた回路
基板の接着方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automobile control device, and particularly to a method for bonding a circuit board that is suitable for mounting in an engine compartment and has excellent vibration resistance and is excellent in preventing board warping and misalignment. .

かりと固定されている。In the conventional waterproof storage case introduced in Utility Model Application Publication No. 57-110972, the circuit board is mounted using a resin circuit board, so it is securely fixed with screws to the cover. .

と、基板が反ったり変形したりする可能性がある。The above conventional technology is a method of firmly screwing the circuit board to the case, so when the board is subjected to load due to vibrations, heat, etc.
The board may warp or deform. As a result, there is a problem that the reliability and vibration resistance of the connector connection portion are lacking. Even when using a pressure welding connector, there is a possibility that the board will warp or deform if it is installed using conventional techniques.

達成することができる。When attaching a circuit board (ceramic board) to an aluminum die-cast cover, for example, there is a difference in coefficient of thermal expansion. In particular, in order to prevent the board from shifting, the bonding surface of the board, which is the connection part of the pressure welding connector, is bonded by making the adhesive injection groove on the case side shallower (for example, using silicone adhesive) to reduce the thickness of the adhesive. To prevent the adhesive from deforming, and to prevent warping, deformation, and misalignment of the board bonding surface other than the pressure welding connector part, use a deep adhesive injection groove on the case side (for example, with silicone adhesive) to prevent warping, deformation, and misalignment. The object of the present invention can be achieved by increasing the thickness of the adhesive and making it easier to deform.

圧接コネクタと回路基板の導通接触部分及び基板全体の
反り１位置ずれを無くすことが出来る。When a load is applied to the circuit board due to vibration or heat, the case structure is such that the adhesive is thicker in areas that can move.
In addition, by creating a case structure in which the thickness of the adhesive is thinner in areas that are prone to movement, and by using different thicknesses of the same adhesive material, it is possible to eliminate the warpage of the conductive contact area between the pressure welding connector and the circuit board, and the entire board. I can do it.

くし接着剤の厚みを小さくして変形しにくい様にする。In FIG. 1, a case 1 has a side opening 1-a to which a prevention connector 2 is attached via a packing 3. The circuit board 5 is attached to the cover 4 with adhesives 8 and 9, and is assembled to the case 1 with screws 7 through the gasket 6. The terminal portion 2-a of the preventive connector 2 and the circuit board 5 are electrically connected by pressure contact. Consisting of the above components, the method of changing the thickness of the adhesive in the circuit board bonding method is to use adhesive 8,
This was done by changing the depth of the adhesive injection groove on the case side for part 9 (same material). Adhesive 8 This part is the connection part of the pressure welding connector, so displacement of the board cannot be tolerated by the supply body, and the load of the connector is considerable, so the adhesive injection groove 1o is made shallow and the thickness of the adhesive is reduced to deform it. Make it difficult.

This makes the adhesive easier to deform. If the depths of the grooves in the adhesives 8 and 9 are reversed, displacement of the connector part is expected. Furthermore, if both the adhesive parts 8 and 9 are formed into shallow grooves, it is expected that the board will warp or deform due to the difference in thermal expansion coefficient between the circuit board and the case.
