Description

백보드 어셈브리의 검사 장치Inspection device of the backboard assembly

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 블럭 구성도,1 is a block diagram of the present invention,

제2도는 본 발명의 크로스 포인트 콘트롤러를 통해 매트릭스 PBA와 연결된 백보드 어셈브리의 각 단자 간 연결을 체크하는 상태의 예시도,2 is an exemplary diagram of a state of checking a connection between terminals of a backboard assembly connected to a matrix PBA through a cross point controller of the present invention;

제3도는 본 발명에서 자체의 선로 연결을 점검하는 과정을 나타낸 플로우 챠트.3 is a flowchart showing a process of checking its own line connection in the present invention.

Claims (1)

소스패턴 제너레이션, 셀프 테스트, 테스트 백보드 및 1페어 모우드로 전환되는 메인 콘트롤러(4)를 이용하여 커트리자 테이프 유니트(1)에 정상적인 패턴을 입력시키고 백보드 어셈브리(2)의 각 단자를 매트릭스 PBA(5)의 케이블(3)과 연결하여, 크로스 포인트 콘트롤러(6)를 통해 각 단자간의 연결상태를 체크하면서 메모리 보드(7)에 기억시켜 카트리지 테이프 유니트(1)에 미리 입력된 패턴과 비교하여 각 단자간의 쇼트나 오픈은 물론 선로간의 신호간섭에 의한 누화도 CRT나 프린터를 통해 알 수 있도록 된 것을 특징으로 하는 백보드 어셈브리의 검사장치.Source pattern generation, self-test, test backboard, and main controller (4) are switched to 1-pair mode. 5) connected to the cable 3, stored in the memory board 7 while checking the connection state between the terminals through the cross point controller 6, A backboard assembly inspection device, characterized in that the short-circuit between the terminals and the open, as well as the crosstalk due to signal interference between the lines can be seen through the CRT or printer. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
