Electrical Performance Evaluation of a Gripper-Type Socket Technology

This paper discusses the electrical characterization and modeling of gripper-type single-sided socket technology to evaluate its performance for high-speed signal applications. The socket was simulated and characterized for multi-ports at high frequencies in single-ended and differential signaling configurations. Three-dimensional numerical simulations were performed with a commercially available 3D FEM (finite element method)-based full-wave software package (Ansoft HFSS). The signal transmission characteristics of the socket pins with 0.5-mm pitch were analyzed by evaluating the Sparameters up to 40 GHz. Single-ended and differential insertion and return loss were evaluated at 5 and 10 GHz.
