- 핑거 테스터(finger tester)를 이용하고, 도체 통로를 구비한, 대형의 컴퍼넌트화되어 있지 않은 회로 기판을 검사하는 방법이며,회로 기판(3)이 몇 개의 세그먼트(segment, I, II, III)로 검사되고, 개개의 세그먼트(I, II, III)가 상기 핑거 테스터의 검사 영역 내에서 연속적으로 검사되며, 그것에 의하여 최종적으로 회로 기판(3) 전체가 검사되고,회로 기판(3)의 각 세그먼트(I, II, III)를 검사하는 때에, 당해 세그먼트를 넘어 연장되는 도체 통로(2)의 개방 상태의 검사가, 세그먼트 내에 위치하는 상기 도체 통로(2)의 단부점의 용량 측정에 의하여, 각각 용량 측정치가 검출되어 행하여지고,어느 세그먼트(I, II, III)의 검사가 종료된 후에 회로 기판(3)이 이동시켜지고, 그것에 의하여, 당해 회로 기판(3)의 다음의 세그먼트(I, II, III)를 상기 검사 영역 내에 배치시키며,단일의 도체 통로(2)의 모든 측정치가 단일의 그룹을 형성하고, 각 그룹 내의 측정치가 서로 비교되어, 적어도 1개의 측정치가 대응하는 그룹 내의 다른 측정치와 소정의 값만큼 다른 경우에 개방 상태라고 판단되는, 방법.
- 제1항에 있어서,최대 길이 40~60mm의 모든 도체 통로(2)가 완전하게 단일의 세그먼트(I, II, III) 내에 위치하도록 세그먼트(I, II, III)가 중복 배치되는 것을 특징으로 하는, 방법.
- 제2항에 있어서,상기 세그먼트는 폭 20~100mm의 가늘고 긴 형상의 영역 내에 있어서 중복하고 있는 것을 특징으로 하는, 방법.
- 제1항 또는 제2항에 있어서,도체 통로(2)는 최대 길이 40~60mm에 걸쳐서 오옴의 법칙에 따른 측정에 의하여 개방 상태의 검사가 행하여지는 것을 특징으로 하는, 방법.
- 제1항 내지 제3항 중 어느 한 항에 있어서,완전하게 단일의 세그먼트(I, II, III) 내에 위치하는 모든 도체 통로(2)는 오옴의 법칙에 따른 측정에 의하여 개방 상태의 검사가 행하여지는 것을 특징으로 하는, 방법.
- 제1항 내지 제5항 중 어느 한 항에 있어서,단일의 세그먼트가 약 200mm×200mm에서 600mm×500mm까지의 크기인 것을 특징으로 하는, 방법.
- 제1항 내지 제6항 중 어느 한 항에 있어서,600mm×500mm보다 크고 800mm×1500mm까지의 크기의 회로 기판(3)이 검사되는 것을 특징으로 하는, 방법.
- 제1항 내지 제8항 중 어느 한 항에 있어서,상기 도체 통로가 개방 상태라고 판단되기 위하여 1개의 측정치가 그룹 내의 다른 측정치와 달라야 하는 정도인 상기 소정의 값은, 상기 1개의 측정치의 전기 용량의 0.5%인 것을 특징으로 하는, 방법.
- 도체 통로를 구비한, 대형의 컴퍼넌트화되어 있지 않은 회로 기판을 검사하기 위한 장치이며, 핑거 테스터와 제어 유닛을 구비하고, 제1항 내지 제8항 중 어느 한 항의 방법을 실행하도록 설계된 장치.
- 제9항에 있어서,검사 대상의 회로 기판의 자동적인 이동을 위한 컨베이어(conveyor)와, 상기 회로 기판을 상기 핑거 테스터의 검사 영역 내에 고정하기 위한 고정구(clamping device, 16)를 구비한 것을 특징으로 하는, 장치.
