Abstract
In a plate bonding system for bonding first and second substrate discs (or other plates) with adhesive, there are provided a first section for bringing the first and second substrate discs closer to each other with the interposition of adhesive, and a second section for producing an electric field in the interspace between the first and second substrate discs. The second section produces the field and thereby deforms the adhesive into a tapered shape to minimize the initial contact area and thereby prevent voids from being involved in the adhesive.
