This step, which we generally refer to as the tray transfer to carrier step. Bulk transfer of the external package and the internal chip is generally performed by using a tray. However, when a specific individual process is operated, a certain degree of requirements, such as high temperature resistance and corrosion resistance, are required for the carrier. The general tray is made of engineering plastics, which cannot completely correspond to high temperature and individual corrosion conditions, and only metal materials which are corrosion-resistant and processed by certain processes can face various more severe conditions. Transferring the product from the tray to the carrier is a very important step.

Because of the requirement of the subsequent process, the product needs to be rotated by 90 degrees for placing, and then the operation of the subsequent process can be carried out. Therefore, in addition to the suction and lifting of the suction heads one by one, the angle of the suction heads needs to be adjusted by rotating the suction heads by 90 degrees in one step.
