PCB 커넥터의 무납땜 결선을 위한 PRESS-FIT 성형 연구
심광보(Kwangbo Shim),유우식(Woosik Yoo) (사)한국CDE학회 2021 한국CDE학회 논문집 Vol.26 No.3
Recently, regulations on lead used in automobiles and electronics have been tightened. In particular, in the case of the existing PCB connector terminals, the use of lead is high, so the demand for the development of solderless PCB connector terminals to replace them is increasing. This paper describes the research on the development of the PCB connector terminal of the solderless connection method through the development of the Press Fit EoN shape terminal. In order to analyze the difference according to the press fit EoN product shape, the test sample was taken out by making two different types of progressive molds using the EoN outer corner “R” molding method of the press fit that has the greatest effect on the insertion force. Insertion and release tests were performed on the PTH with the extracted sample, and the required force was measured and compared. The press-fit EoN terminal developed in this study was applied to the soul power window switch of “Company K” and is being used as an eco-friendly PCB connector terminal.
