Abstract

본 발명은 전압조정기와 엔진점화 장치의 리드 프레임 연결에 관한 것으로, 회로기판과 하우징 리드 프레임의 연결에서 레이저 용접을 실시하여 니켈 스트립을 연결하는 방법에 관한 것이다.The present invention relates to a lead frame connection of a voltage regulator and an engine ignition device, and a method of connecting nickel strips by laser welding in connection of a circuit board and a housing lead frame.

본 발명은 회로기판의 용접판 상면에 니켈층을 형성하고 하우징의 리드 프레임과 상기 용접판의 니켈층에 레이저 용접을 실시하여 니켈 스트립을 연결한다. 상기와 같은 본 발명은 알루미늄 대신 니켈을 사용함으로서 단가를 줄이 수 있고 산화막의 발생을 방지하며 부착 강도를 높일 수 있는 효과가 있다.The present invention forms a nickel layer on the upper surface of the welding plate of the circuit board and performs a laser welding on the lead frame of the housing and the nickel layer of the welding plate to connect the nickel strips. The present invention as described above can reduce the unit cost by using nickel instead of aluminum, it is possible to prevent the occurrence of the oxide film and increase the adhesion strength.
