PHOTONIC SINTERING OF POLYMER THICK FILM COPPER CONDUCTOR COMPOSITIONS

摘要

This invention provides a method for using a polymer thick film copper conductor composition to form an electrical conductor in an electrical circuit, the method subjecting the deposited thick film copper conductor composition to photonic sintering. The invention also provides a method for reducing the resistance of an electrical conductor formed from a polymer thick film conductor composition, the method comprising the step of subjecting the electrical conductor to photonic sintering. The invention further provides devices containing electrical conductors made by these methods. The invention also provides a polymer thick film copper conductor composition.
