ABSTRACT:
An in-circuit test machine testing a printed circuit board (PCB). The test machine is placed in contact with soldered terminals of circuit components mounted on the printed circuit board and measures values of parameters of the respective circuit components. The measured values are compared with reference values stored in a data storage unit in the test machine. According to the result of the comparison, it is determined whether the circuit components are defective or not defective. The apparatus includes a connector tester testing terminals of a connector mounted on the printed circuit board in order to determine whether the terminals are defective or not defective. The terminals of the tested connector include terminals for data signal input and output, control signal input and output, and power input and output.
