  • High-speed pluggable rigid-end flex circuit
    Patent number: 9204537
    Abstract: High-speed pluggable rigid-end flex circuit. A circuit includes a flexible section, rigid section, connector disposed on the rigid section, and electrically conductive signal transmission line electrically coupled to the connector. The flexible section includes a first portion of a flexible insulating layer. The rigid section includes a second portion of the flexible insulating layer and a rigid insulating layer disposed on the second portion of the flexible insulating layer. The connector is configured to form a pluggable conductive connection. The electrically conductive signal transmission line includes a first signal trace having a root mean square surface roughness below 20 micrometers and a filled signal via configured to pass through at least a portion of the rigid insulating layer. The flexible and rigid insulating layers have a dissipation factor equal to or below a ratio of 0.004 and a dielectric constant equal to or below a ratio of 3.7.
