Abstract
A shielded electrical ribbon cable includes a plurality of conductor sets. Each conductor set is surrounded by a shield and includes two insulated conductors. First and second non-conductive polymeric layers are disposed on opposite sides of the cable. The polymeric layers include cover portions and pinched portions. The cover portions surround the plurality of conductor sets, and the pinched portions form pinched portions on each side of the cable. The cable includes a transition portion on each side of the cable. At least one of the polymeric layers has a radius of curvature of at least 50 microns across an entire width of the cable. For at least one of the polymeric layers, the ratio of the minimum radius of curvature in the cover portions to the minimum radius of curvature in the transition portions is from 2 to 15.
