The Carbon Ink FPC offers robust, conductive graphite contact printing engineered for extensive mechanical wear and stable electrical resistance. Hardware engineers and procurement managers utilise these flexible circuits in input controllers, membrane switches, and human-machine interfaces requiring millions of actuation cycles without signal degradation. By leveraging precision screen-printing techniques, we apply carbon paste over designated trace areas to prevent oxidation while providing a durable contact surface.
