Abstract
An improved squeegee for screen printing a thick film ink onto a substrate of a microelectronics circuit in order to form a thick film on the substrate. The squeegee is specifically configured to eliminate the creation of voids in a thick film deposited using the squeegee by enhancing the flow characteristics of the thick film ink as it is forced through a printing screen by the squeegee. Improved flow characteristics are achieved be appropriately configuring the cross-sectional profile of the squeegee in order to localize the printing forces on the ink at the working edge of the squeegee, in order to prevent ink ahead of the working edge from prematurely filling the openings in the screen.
