Abstract
본 발명은 피씨비(PCB) 검사장치에 관한 것으로, 피측정보드의 내부에 배치된 부품과 픽스처의 핀이 1 : 1로 연결되면 상기 픽스처의 핀 중 검사하고자 하는 검사핀과 연결되어 정전압을 공급하는 소스 릴레이와 상기 피측정보드의 부품을 통해 상기 검사핀과 연결되며 일측이 접지된 다수의 응답 릴레이로 이루어진 스위칭부와, 상기 스위칭부의 소스 릴레이에 저항을 거쳐 정전압을 공급하며 상기 저항 양단의 전압을 측정 및 비교하여 검사핀의 상태를 판단하는 측정부를 포함하여 구성되며, 픽측정보드의 검사 전에 상기 픽스처의 핀 상태를 상기 저항 양단 중 입력측의 전압이 출력측보다 크면 핀과 측정보드가 접촉하여 검사핀의 상태가 양호한 것으로 판단하고, 입력측 전압이 출력측과 동일하면 접촉되지 않은 것이므로 검사핀에 이상이 있는 것으로 판단, 점검하여 양산 라인에서의 측정핀과 픽스처 사이의 접촉불량으로 인한 가성오류를 제거함으로써 신뢰성 확보 및 생산효율을 극대화할 수 있는 효과가 있다.The present invention relates to a PCB (PCB) inspection device, when the pins of the components and fixtures arranged inside the measurement board is connected to 1: 1 is connected to the test pin to be tested among the pins of the fixture to supply a constant voltage A switching unit consisting of a plurality of response relays connected to the test pin and grounded at one side through a source relay and a component of the measurement board, and supplying a constant voltage through a source relay of the switching unit and supplying a voltage across the resistor. And a measuring unit for measuring and comparing the test pins to determine the state of the test pins. If the pin state of the fixture is greater than the output side of the resistor before the test of the pick measuring board, the pin and the test board are in contact with each other. If the input voltage is the same as the output side, it is not contacted. Determined, a check and to maximize the reliability and production efficiency by removing caustic errors due to poor contact between the measuring pin in a mass production line and fixture effects.
