Abstract

The invention relates to a flying probe tester movement shaft positioning precision test system and a test method thereof. The flying probe tester movement shaft positioning precision test system comprises a laser assembly, an angle turning lens group, a reflector group and a single light splitter group. The laser assembly is used for generating a laser beam; the angle turning lens group is used for propagating the laser beam; the reflector group is used for reflecting the laser beam to enable the laser beam to be reflected back into the laser assembly; and the single light splitter group is sued for propagating the laser beam. The flying probe tester movement shaft control method and positioning precision compensation method ensures that a flying probe tester has higher test precision, thereby solving the problem of low test precision of the flying probe tester. Besides, the flying probe tester movement shaft positioning precision compensation method is easy to operate and low in cost.

Description

Technical field [0001] The invention relates to the technical field of testing of printed circuit boards, in particular to a testing system and a testing method for the positioning accuracy of a moving shaft of a flying probe testing machine. Background technique [0002] The flying probe tester includes X-axis motion axis and Y-axis motion axis. Probes driven by motors are installed on both X-axis and Y-axis motion axes. The probes are driven by the corresponding motors to move in the Z-axis direction. To make contact with the solder joints on the printed circuit board to perform electrical measurements on the printed circuit board. Due to the functional requirements of the flying probe tester, the two ends of the Y-axis motion axis are respectively erected on the two X-axis motion axes, and the distance between the two ends of the Y-axis motion axis is relatively large, and the Y-axis motion axis is installed on the X axis by two The motor of the motion axis is driven or drive...
