Abstract

This study proposes an structure that fixes the shielding device to two parts of the board by its two arranged clips. Said structure evenly distributes its loading/unloading load of the board and maintains the flatness of soldering area of the board. The structure of this study comprises a base part fixed to a printed circuit board and a clip part fixing a side wall of a shield can to the board, wherein the clip part is constituted with two clips fixable to two part of the shield can. Also, the structure of this study comprises a dented groove in order to easily solder the base part of clips and the printed circuit board. A mechanism is established and a design parameter was determined by a structure analysis and a vibration mode analysis. A single purpose machine for the production of the product was developed, the final workpiece was produced and the measuring-data and the computered-data was compared and reviewed.

본 연구에서는 양쪽 대칭으로 지지할 수 있는 쉴드캔 클립을 제안하며, 그 특징은 장착과 탈착의 하중을 일정하게 하고 납땜 부위의 평판도를 유지 할 수 있도록 개발하였다. 또한 인쇄회로기판에 부착 고정되는 베이스부 및 쉴드캔의 측벽을 집게 형태로 집을 수 있도록 하는 클립부로 구성되며, 클립부 중앙을 절단하여 2군데를 지지 할 수 있게 이루어진다. 또한 넓어진 베이스부와 인쇄회로기판 사이에 납땜이 잘될 수 있도록 오목한 홈을 만들었다. 연구절차는 우선 메커니즘을 설정하고 구조해석 및 진동모드 해석을 수행하여 설계변수를 확정한 후, 제품을 설계하였다. 제조를 위한 전용기를 개발한 후 시제품을 제작하여 성능 평가 후 해석값과 비교 분석하였다.
