REDUCTION OF STRAY LIGHT DURING SINTERING

摘要

A conductive particle sintering system has light blocking coating, aperture, or shutter to allow energy from a radiant source, such as a flash lamp, to reach a desired portion of a workpiece to be sintered, while blocking stray light from reaching other workpieces and/or other portions of a workpiece being processed to prevent stray light from partially sintering the other workpieces and/or other portions of a workpiece.
