Method for aligning two objects

摘要

A system for aligning a mask and a product with high precision, featuring a means for supporting a product in a fixed position and a mask adjacent to the product so that the mask is movable relative to the product. A plurality of computer controlled plungers push the surrounding mask frame into alignment. A computer is used to determine the relative position of the mask and the product prior to alignment; and that, to achieve proper alignment of the mask and the product, and determines the distance that the mask must be moved.
