PHOTO-CURING PROCESS FOR CONDUCTIVE INKS

摘要

PROBLEM TO BE SOLVED: To provide a photo-curing process for conductive inks.SOLUTION: A solution of metal ink is mixed and then printed or dispensed onto a substrate using a dispenser. The film then is dried to eliminate water or solvents. In some cases, a thermal curing step can be introduced subsequent to dispensing the film and prior to the photo-curing step. The substrate and deposited film can be cured using an oven or by placing the substrate on the surface of a heater, such as a hot plate. Following the drying and/or thermal curing step, a laser beam or focused light from a light source is directed onto the surface of the film in a process known as direct writing. The light serves to photo-cure the film such that the film has low resistivity.
