Abstract

The invention relates to a flying probe tester motion axis control method and positioning accuracy correction method. The flying probe tester motion axis positioning accuracy correction method comprises the steps that a correction plate is designed according to the test area of a flying probe tester, wherein the correction plate is provided with a latticed test point matrix, the four vertexes of the test point matrix are the test point A, the test point B, the test point C and the test point D, and the connecting line direction of the test point A and the test point B is the X-axis direction;the allowable value of the positioning error of the test point matrix in the X-axis direction and the Y-axis direction is set; the coordinate data of each test point of the test point matrix relativeto one of the test point A and the test point B are tested by using an automatic optical detector; and the correction plate is arranged in the test area. The corrected XY-axis accuracy of the flying probe tester is the positioning accuracy of testing so that the flying probe tester is ensured to have high test accuracy and the problem of low test accuracy of the flying probe tester can be solved.

Description

technical field [0001] The invention relates to the technical field of testing printed circuit boards, in particular to a method for controlling the motion axis of a flying probe tester and a method for correcting positioning accuracy. Background technique [0002] The flying probe testing machine includes an X-axis and a Y-axis. Probes driven by motors are installed on the X-axis and Y-axis. The probes are driven by the corresponding motors to move in the Z-axis direction. To make electrical measurements on printed circuit boards by making contact with solder joints on the printed circuit board. Due to the functional requirements of the flying probe testing machine, 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 Driven by the motor of the motion axis or by a single motor mounted on ...
