Electroconductive coating composition, a printed circuit board fabricated by using it and a flexible printed circuit assembly with electromagnetic shield

摘要

The invention provides a conductive, flexure-resistant electromagnetic- shielded flexible printed circuit assembly obtainable by forming a copper foil circuit on a heat-resistant plastic film, disposing successively thereon an undercoat layer, a metal-powder- containing electromagnetic paste shield layer and an overcoat layer, with the ground pattern of the copper foil circuit being electrically connected to the above shield layer through the undercoat layer at appropriate intervals.
