ABSTRACT:
An apparatus for testing a circuit board has a holder for holding the circuit board, a detector for detecting the electrical characteristics of the circuit board, and a controller for controlling laser plasma switches. The detector has a path forming unit positioned away from the circuit board by a predetermined gap. The path forming unit forms a first conductive path between a position corresponding to a first test pad on a trace of the circuit board and a first power source, as well as a second conductive path between a position corresponding to a second test pad on another trace of the circuit board and a second power source. The controller emits a laser beam to a first space between the first test pad and the first conductive path and another laser beam toward a second space between the second test pad and the second conductive path, to make the first and second spaces conductive. The detector has a sampler connected to one of the first and second conductive paths, to sample electrical characteristic values of the circuit board.
