Abstract:
A method for printing conductive solder paste on a base substrate to establish an electrical connection is provided. The method includes applying conductive solder paste over a stencil, and within an opening of the stencil to contact the base substrate therebeneath. In embodiments, a squeegee can be used to scrape some of the conductive solder paste off of the stencil, leaving behind some of the conductive solder paste within the opening. Subsequently, the stencil can be removed at a speed of more than 200 millimeters per second to help reduce the end-of-track bump ultimately formed at the end of the conductive solder paste that remains after the stencil is removed.
