Liquid Ink Jet Printing with MOD Inks for Hybrid Microcircuits

Application of the computer-controlled impulse ink jet with liquid metallo-organic decomposition (MOD) inks is demonstrated to be feasible in printing hybrid microcircuits. The advantages of ink jet printing over conventional screen printing are discussed. The hardware and software of the ink jet printing system have been developed. The MOD ink system suitable for the ink jet has been studied. Printing experiments with the ink jet have been conducted during the research. A theoretical model has been derived relating the ink jet flow rate to the primary spray control parameters. The ink jet system with silver neodecanoate MOD ink has been applied to metallize the grid pattern of silicon solar cells.
