PHOTONIC SINTERING OF A SOLDERABLE POLYMER THICK FILM COPPER CONDUCTOR COMPOSITION

摘要

This invention provides a polymer thick film copper conductor composition for forming a solderable and highly solder leach resistant electrical conductor and a method for using the polymer thick film copper conductor composition to form the electrical conductor in an electrical circuit. The method subjects the deposited thick film copper conductor composition to photonic sintering. The invention further provides electrical devices containing electrical conductors made from the polymer thick film copper conductor composition and also those formed by the method.
