Abstract
A novel electroformed squeegee blade for the uniform deposition of printing material such as solder paste and the like onto printed wiring boards is disclosed. A method of fabricating the electroformed squeegee blade is also disclosed. The method of fabrication, which produces an electroformed squeegee blade having smooth, planar, and flat surfaces, involves electroforming at least one uniform layer of metal onto a conductive substrate and removing the substrate. Also disclosed is an apparatus and method that employ the electroformed squeegee blade to uniformly deposit printing material on printed wiring boards.
