Abstract
Description
본 발명에 의한 전자파 차폐장치는 금속패턴이 형성되고 전자 소자가 실장된 기판; 상기 금속패턴과 전자 소자를 통전시키는 와이어; 상기 와이어의 일부와 상기 전자 소자가 매몰되도록 상기 기판 위에 형성된 몰딩층; 및 상기 몰딩층 표면에 형성되어 상기 와이어와 통전되는 도전체층을 포함한다.
본 발명에 의한 전자파 차폐장치 제조 공정은 금속패턴이 형성된 기판에 전자소자가 실장되는 단계; 상기 금속패턴 영역의 기판에 금속부재의 일부가 삽입되어 고정되는 단계; 상기 금속부재와 상기 전자소자를 포함한 기판 영역에 몰딩층이 형성되는 단계; 및 상기 금속부재와 통전되도록 상기 몰딩층 표면에 도전체층이 형성되는 단계를 포함한다.
본 발명에 의한 전자파 차폐장치 제조 공정은 와이어를 통하여 기판 상의 금속패턴과 전자소자가 연결되는 단계; 상기 금속패턴, 상기 전자소자 및 상기 와이어를 포함한 기판 영역에 몰딩층이 형성되는 단계; 및 상기 와이어와 통전되도록 상기 몰딩층 표면에 도전체층이 형성되는 단계를 포함한다.
이하에서 첨부된 도면을 참조하여 본 발명의 실시예에 따른 전자파 차폐장치 및 전자파 차폐장치 제조 공정에 대하여 상세히 설명한다.
즉, 상기 본딩 와이어(330)는 상기 몰딩층(320) 내부에서 전자소자(340), 금속 패턴(370), 도전체층(310)을 통전시키는 구조를 가진다.
반면, 제1실시예에 따른 전자파 차폐장치(200)를 제작하는 경우에는, 일반적인 전자소자의 실장공정, 와이어 본딩 공정과 함께 메탈핀 삽입 공정이 수행되는데, 본 발명의 실시예에서 상기 메탈핀(230)은 햄머링 방식을 통하여 기판(260)의 접지용 비아홀(270)에 삽입되거나 기판(260)에 직접 박힐 수 있다(S230).
또한, 몰딩층(220, 320)의 표면이 매끈하게 가공됨으로써 도금된 도전체층(210, 310)이 몰딩층(220, 320)의 표면과 보다 강하게 결착될 수 있다.
