Abstract

본 발명은 전압조정기의 리드 프레임 연결에 관한 것으로, 전압조정기 하우징의 리드 프레임과 기판의 니켈층을 직접 접촉시켜 용접을 실시하여 작업의 편리성을 증가하며 보다 견고한 용접을 하는 데 그 목적이 있다.The present invention relates to a lead frame connection of the voltage regulator, the welding is performed by directly contacting the lead frame of the voltage regulator housing and the nickel layer of the substrate to increase the convenience of work and to provide a more robust welding.

본 발명은 기판에 위치한 도체 상면에 용접판과 니켈층을 형성하고 전압조정기 하우징의 리드 프레임의 일단을 상기 기판 상면의 니켈층 상측부에 위치시키고 니켈층과 접하는 리드 프레임에 레이저 용접을 실시하여 용접점을 형성한다.The present invention forms a welding plate and a nickel layer on the upper surface of the conductor located on the substrate, and place one end of the lead frame of the voltage regulator housing on the upper nickel layer of the upper surface of the substrate and perform laser welding on the lead frame in contact with the nickel layer. Form a point.

상기의 본 발명은 강한 접착강도를 가지며, 빠르고 깨끗한 용접을 실시하여 양질의 제품을 생산하는 효과가 있다.The present invention has a strong adhesive strength, there is an effect of producing a good quality product by performing a fast and clean welding.
