Thereafter, the material holding device is pushed to slide and reset by the pushing mechanism, and then the shift mechanism moves the chip on the material holding device according to the process, wherein the chip of the last process is moved out of the material holding device, and at the same time the first test station on the material holding device is vacated, and the new chip to be tested is placed in the first test station by an external robotic arm.
