Abstract

Un interruptor fusible de película delgada montable en superficie que tiene dos subensambles de material. El primer subensamble incluye un enalce fusible, su substrato de soporte y contactos terminales. El segundo subensamble incluye una capa protectora que cubre al enlace fusible para proporcionar proteccion contra golpes y oxidacion. La capa protectora está hecha preferentemente de un material polimérico. El material polimérico más preferido es un gel o pasta de poliuretano. En adicion, el substrato de soporte más preferido es un epoxi FR-4 o una poliimida.
