摘要

Advances in electronics packaging and assembly technology are driving increased demand for ultra-fine pitch solder deposition. In this work, innovative solder deposition techniques based on laser printing are investigated for low-cost ultra-fine pitch printing applications. This paper investigates the feasibility of using solder particles in off-the-shelf xerographic technology. The physics of two development systems (dual component and monocomponent) is discussed. This inquisition leads to a discussion of triboelectric charging of the solder toners, coating the solder with thin dielectrics, and charge induction by an applied electric field. This initial investigation explores the basic feasibility of xerographic printing techniques using solder and defines future work.
