Description
Claims (3)
- 피측정용 인쇄회로 기판과, 상기 인쇄회로기판의 전기적 패턴상태를 검사하기 위한 검사수단을 구비하는 인쇄회로기판의 패턴검사장치에 있어서,상기 검사수단은,상기 피측정 인쇄회로기판 상의 검사하고자 하는 소정의 패턴 위치에 대응하도록 형성한 패턴과, 상기 형성된 패턴을 검사하기 위해 탐침이 삽입되도록 형성된 홀을 구비한 커넥션 인쇄회로기판과,상기 커넥션 인쇄회로기판을 장착하도록 구성되고, 상기 탐침에 의해 상기 측정용 인쇄회로 기판의 상기 피측정 인쇄회로기판과 접속하도록 구성된 픽스쳐를 구비하는 것을 특징으로 하는 인쇄회로기판의 패턴검사장치.
- 제 1 항 기재의 인쇄회로기판의 패턴 검사장치의 피측정 인쇄회로기판의 패턴에 일정 시간동안 과전류를 인가하는 단계와,상기 과전류 인가시 상기 피측정 인쇄회로기판의 패턴에서 변화하는 저항치를 검출하여 패턴의 연결 상태를 검사하는 단계를 포함하는 것을 특징으로 하는 인쇄회로기판의 패턴검사방법.
- 제 2항에 있어서,상기 과전류 인가하는 단계에서 스위칭소자로서 전계효과 트랜지스터를 사용하는 것을 특징으로 하는 인쇄회로기판의 패턴검사방법.
