CIRCUIT BOARD TEST SYSTEM, CIRCUIT BOARD TEST METHOD AND CIRCUIT BOARD CLAMPING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a circuit board test system.SOLUTION: A circuit board test system comprises: a test device that has a test stage, and is arranged so as to conduct tests to circuit boards placed in the test stage; a buffer stage that is located out of the test device; two clamp jigs that are placed in the test stage and the buffer stage, respectively, and are arranged so as to clamp the single circuit board, respectively; an ejection/retracting device that includes two ejection/retracting modules moving between the test stage and the buffer stage respectively, and are arranged so as to eject or retract one jig in the clamp jigs; and one or more controllers that is arranged to actuate the ejection/retracting module so as to interchange an arrangement position of the clamp jigs after the test is conducted to the circuit board to be placed in the test stage in the test device.SELECTED DRAWING: Figure 1
