Furthermore, the multi-axis motion module 130 is used to adjust the position of the universal stage 120, so that after the product to be tested is placed on the universal stage 120, it moves to the corresponding position for circuit connection and then testing. Furthermore, the CCD module 140 is used to adjust the position of the product to be tested and to perform position compensation. It can be understood that due to possible deviations in the placement position... Corrections are needed before testing to avoid interfering with the results.
