<P>PROBLEM TO BE SOLVED: To provide a printed circuit board test apparatus which facilitates the determination of soundness including detection of failures with conduction such as being in a pseudo-contact state, floating capacitance by foreign objects and the like, or failures due to inductive coupling. <P>SOLUTION: A printed circuit board test apparatus makes a first device 12 that is compliant with boundary scan output a test signal with a predetermined pattern depending on a defect mode, measures, at an in-circuit test measurement part 2b through a probe 5, a voltage generated at a lead part 13a of a second device 13 that is non-compliant with boundary scan having the lead part 13a and being connected to the first device through the lead part 13a and a printed wiring 11a, and determines, at a cooperative operation determination part 3b based on the above measured voltage, whether or not there is any connection failure between the first and the second devices of a printed circuit board 10. The printed circuit board test apparatus can facilitate a determination of soundness because it makes the first device 12 output the test signal and measures the voltage generated at the lead part 13a of the second device 13 at the probe 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
