Abstract

와이어 본딩 장치는 IC칩의 전극 패드와 리드 프레임의 대응하는 내부 리드를 포함하는 와이어 본드 물체를 둘러싸는 정방형 영역의 화상 프레임의 화상 데이타를 얻기위한 화상 픽업 유니트를 갖는다. 정방형 영역의 화상은 본딩 동작이 이행되는 본딩 스테이션에서 픽업된다. 화상 데이타는 각각의 내부 리드와 전극 패드의 위치와 메모리 유니트에 저장된 대응하는 설계위치로부터 각각의 와이어 본드 물체의 위치의 계산 편차를 검출하는 화상처리 유니트로 전송된다. 제어 유니트는 와이어 본드 물체의 각각의 본딩 점으로 본딩 틀을 정렬하기 위한 편차를 기초로 하여 XY테이블을 제어한다. 리드 프레임, 테이프 캐리어 또는 세라믹 패키지의 경우에, 와이어 본딩의 정확도는 전송, 열 변형, 열 팽창, 또는 화상 픽업 유니트에 남아있는 진동으로 인해 내부 리드의 변형에 의해 영향을 받지 않고 개선된다. 부가적으로, 검출 동작으로 위해 요구되는 시간의 양은 감소될 수 있다.
