Description
도 2는 본 발명에 따른 다이오드 패키지를 설명하기 위한 평면도;
도 3은 도 2의 A-A'선에 따른 단면도;
도 4는 상부 리드 프레임을 설명하기 위한 평면도;
도 5는 도 4의 A-A'선에 따른 단면도;
도 6은 하부 리드 프레임을 설명하기 위한 평면도;
도 7은 도 6의 A-A'선에 따른 단면도;
도 8은 도 4의 상부 리드 프레임과 도 5의 하부 리드 프레임의 조립과정을 설명하기 위한 평면도;
도 9는 도 8의 A-A'선에 따른 단면도;
도 10은 본 발명에 따른 다이오드 패키지의 설치예를 설명하기 위한 도면이다.
반구형 접촉부(132)에 관통공(133)이 없는 경우도 본 발명의 범주에 포함된다. 이 때에는 반구형 접촉부(132)의 밑부분과 다이오드 칩(110)을 납땜하게 될 것이다. 상부 리드선(130)과 하부 리드선(140)이 다이오드 칩(110)에 전기적으로 접속되어야 다이오드의 기능을 수행할 수 있다는 것은 당업자에게 자명한 것이므로 이렇게 관통공(133)이 없는 경우에는 반구형 접촉부(132)의 밑단과 다이오드 칩(110)을 납땜하는 것이 당연하다. 반구형 접촉부(132)는 다이오드 칩(110)에 납땜으로 접합시킬 때에 접합유효면적 내에서 접합면적을 최대화하고 정교하게 접합되도록 함으로써 접합재 또는 납땜 공정에서의 불량을 방지하고 수율을 향상시킴과 동시에 접합부의 전기 전도율을 향상시키고 구동시에 발생되는 열전도를 향상시키기 위한 것이다.
