Abstract
Passive stamp alignment system. The system includes a stamp supported by a stamp holder resting on three balls affixed to a top platform. A bottom platform supports a substrate to be aligned with the stamp. Means are provided for moving either the top or the bottom platform and holding the other platform stationary so as to contact the substrate with the stamp whereby the stamp holder is lifted away from each of the balls in sequence resulting in alignment of the stamp and the substrate parallel to each other.
