Abstract
The pick-up head picks up the semiconductor elements from the carrying area of the carrier plate first. Then the pick-up head moves the semiconductor elements to the dipping area to dip the flux, and moves the image detector to the carrying area of the carrier plate to detect, so as to obtain a pick-up image. After that, the pick-up head places the semiconductor elements on the placement area of the target substrate. Finally, the pick-up head moves to another carrying area of the carrier plate to pick up the semiconductor elements, and the image detector moves to the placement area of the target substrate to detect, so as to obtain a placement image. Thus, the method can record the pick-up and placement results in time, so as to improve the process and increase the process stability.
