Description

캐리어 엘리먼트
본 발명은 칩 카드에 결합되는 캐리어 엘리먼트에 관한 것으로, 상기 캐리어 엘리먼트는 리드 프레임으로 보통 명명되는 컨덕터 캐리어에 배치되고, 컨덕터 캐리어의 접촉 댑에 전기적으로 연결되는 반도체 칩을 갖는데, 최소한의 상기 반도체칩과, 상기 접촉 댑과 상기 반도체 칩의 연결을 위해 제공된 본드-와이어는 상기 접촉 댑이 반도체 칩과의 전도성 연결로 인해 플라스틱 화합물로부터 빠져나오도록 플라스틱 화합물에 의해 둘러 쌓이게 된다.
이러한 캐리어 엘리먼트는 유럽 특허 공개 제 0,254,640 A1호에 공지되어 있다. 이 공지된 캐리어 엘리먼트는 기계적인 접촉에 의한 접촉 탭을 통해 리더가 요구하는 만큼의 전력이 공급되는 칩 카드에 삽입된다. 또한 데이타 흐름은 기계적인 접촉에 의한 접촉 탭을 통해 발생한다.
독일 특허 제 4,115,065 C2호에는 무 접촉 칩 카드를 개시하고 있는데, 전력과 데이타는 안테나 코일을 통해, 다시 말해 유도 결합을 통해 전송된다. 여기서 안테나 코일의 단부는 외부에 대해 어떤 다른 접촉을 갖지 않는 칩 카드의 반도체 칩에 연결된다. 그러한 무 접촉 칩 카드의 칩 테스트는 설치된 코일을 통해서만 가능하다.
본 발명은 칩 카드에 결합되는 캐리어 엘리먼트에 관한 것이다.
도1 및 도2는 본 발명에 따른 캐리어 엘리먼트를 통해서 본 단면도.
도3는 설치된 캐리어 엘리먼트의 공간적인 도면.
본 발명의 목적은 무 접촉 칩 카드에 결합하는데 적합하고, 연결된 코일 없이 테스트가 가능하며 이 카드에 코일을 설치하는데 적합한 캐리어 엘리먼트를 기술하는데 있다.
이러한 목적은 청구항 1항에 따른 캐리어 엘리먼트에 의하여 성취된다. 본 발명의 부가의 개선은 종속항에서 구체화된다.
본 발명에 따라 상기 반도체 칩의 플라스틱 슬리브의 한 표면에서 접촉 탭을 통한 접촉 영역의 구성결과로, 기계적인 접촉에 의한 칩으로의 전기적인 엑세스는 안테나가 접촉 탭 연장부에 연결되지 않고 테스트 목적을 위해 가능하다, 그러나, 테스트는 안테나가 연결될때도 가능하지만, 이것은 본 발명에 따른 구성으로 인해 소용이 없다.
접촉 탭 연장부가 캐리어 엘리먼트의 반대측에 배치되면, 캐리어 엘리먼트는 평면 코일의 와인딩에 유리한 방법으로 직접 세트될 수 있고 코일의 단부에 접촉될수 있으며, 그 결과 코일의 단부는 와인딩에 겹쳐질 필요가 없으며; 이러한 방법으로 캐리어 엘리먼트와 코일간의 연결 제조가 쉽게 자동화될 수 있으며, 이러한 제조에 의해, 코일의 품질만큼 코일의 재생산성도 높아진다.
다른 길이를 갖는 접촉 탭 연장부를 구성함으로서, 코일 단부의 겹침이 없는 접촉이 마찬가지로 가능해지는데, 왜냐하면, 더 긴 접촉 탭의 연장부가 와인딩 위 또는 아래로 유인되기 때문이다. 이러한 장치에서 캐리어 엘리먼트는 칩 카드 가장자리 또는 한 모서리에 근접하여 배치될 수 있으며, 그 결과 캐리어 엘리먼트는 칩카드의 중앙선으로부터 이격 배치되며, 칩 카드의 중앙선은 휘는 압력에 의해 심하게 로드된다.
본 발명을 도면을 참고로 예시적인 실시예와 관련하여 더 상세히 설명하겠다. 도1, 도2 및 도3에 따르면, 반도체 칩(2)은 예를 들어 컨덕터 캐리어(1)에 결합되어 고정되며, 본드-와이어(3)에 의하여 접촉 탭(5,6 또는 5,7)에 도전적으로 연결된다. 반도체 칩과 본드-와이어(3)는 하우징(4)을 형성하는 캐스트 플라스틱 화합물(4)에 의해 둘러 쌓여 있다. 컨덕터 캐리어(1)의 접촉 탭은 플라스틱 화합물(4)의 한 표면에 배치되는 접촉 영역(5)을 형성하도록 모양을 갖추고 있다. 접촉 영역(5)의 연장부는 안테나 코일의 단부를 위한 연결부(6,7)를 형성한다. 도1에서, 접촉 탭 연장부는 2번 이상 구부러지며, 그 결과 이 연장부는 안테나 와인딩 아래로 유인될 수 있다. 도2에서, 접촉 탭의 연잡부는 접촉 영역과 동일한 면에 연장되며, 그 결과 상기 연장부는 안테나 와인딩 위로 유인된다. 도3은 본 발명에 따른 캐리어 엘리먼트의 특히 바람직한 어셈블리를 나타낸다. 여기서, 캐리어 엘리먼트는 평면 코일의 와인딩(9)에 바로 설치되고, 상기 캐리어 엘리먼트의 반대측에 배치된 2개의 접촉 영역 탭 연장부는 코일의 단부에 연결된다. 이런 방법으로, 캐리어 엘리먼트는 코일 와인딩 양단에 링크를 형성한다. 그러므로, 특히 용이하게 자동화 될 수 있고 바람직하게 재생될 수 있는 설치가능성이 주어진다. 안테나 와인딩(9)은 이 경우에 카드 인서트(8)에서 인쇄된 선으로 수행될 수 있다. 본 발명에 따른 캐리어 엘리먼트의 경우에, 반도체 칩은 기계적인 접촉에 의한 문제없이 접촉영역(5)에 의해서, 설치된 캐리어 엘리먼트의 경우와 또한 설치되지 않은 캐리어 엘리먼트의 경우 모두에 테스트 될 수 있다.
