| description | A flexible circuit (10) incorporating an electrostatic discharge limiting feature, comprising a dielectric substrate selected from polyimide or liquid crystal polymer film having at least one conductive trace (30) coated on at least one surface of the substrate wherein the discharge limiting feature includes a thin conductive polymer coating (60) selectively applied over a at least a portion of the non-critical region (50) of the circuit, said feature reducing the surface resistivity of the circuit to about 10 ohms to about 10 ohms and having tribocharging of less than about 50 V.
L'invention porte sur un circuit souple (10) muni d'un élément limitant les dommages dus aux décharges électrostatiques et comprenant: un substrat diélectrique choisi parmi un film de polyimide ou de polymère à cristaux liquides, dont l'une au moins des surfaces présente au moins un tracé (30) conducteur; et ledit élément limitant les dommages, qui consiste en un mince revêtement (60) de polymère conducteur sélectivement appliqué sur l'une au moins des zones (50) non critiques du circuit, et qui ramène la résistivité surfacielle du circuit d'environ 10 ohms à environ 10 ohms, tout en limitant la tension triboélectrique à moins d'environ 50V. |
