Abstract:
An electronic device may include flexible printed circuits. A flexible printed circuit may have metal traces supported by a polymer substrate. The flexible printed circuit may extend between an upper laptop computer housing and a lower laptop computer housing or other structures that move relative to each other in an electronic device. The flexible printed circuit may have a low-friction coating and a matte finish. The flexible printed circuit may have a fluoropolymer coating on the polymer substrate, a fluoropolymer coating on a matte coating on the polymer substrate, a fluoropolymer coating that includes a matting agent on the polymer substrate, a fluoropolymer layer or other polymer layer that is attached to the substrate with a layer of adhesive, a textured surface layer, and/or other structures that help provide the flexible printed circuit with desired physical properties and a desired appearance.
