Description

ELECTRICAL CONNECTOR APPARATUS AND METHOD BY JONATHAN BUCK TROY B. HOLLAND BRANDON GORE AND ANDREW JOSEPHSON ATTORNEY REFERENCE: SAMTE-0009-WG-05 CROSS-REFERENCE TO PREVIOUS APPLICATONS [0001]This application claims priority from United States provisional patent application no. 63/511,451 filed on June 30, 2023, United States provisional patent application no. 63/625,851 filed on January 26, 2024, and United States provisional patent application no. 63/633,390 filed on April 12, 2024, the entire contents of which are hereby incorporated herein by reference in its entirety. TECHNICAL FIELD [0002] The present embodiments relate generally to an electrical connector apparatus/assembly, with particular embodiments shown for an electrical connector. BACKGROUND [0003] Typical connectors intended to operate at 112G/224G PAM4 signaling may require a larger width of the die package substrate to accommodate. However, this practice of increasing the size of the die package substrate may increase insertion loss and/or make the die package substrate more susceptible to curling, warping, and/or losing coplanarity during reflow. Thus, there is a need to improve the die package substrate size, reduce the width of the connector, minimize coplanarity issues, and/or minimize insertion loss. [0004] Mechanical, separable connectors can have mating cycle limitations, plating limitations, thermal limitations, size limitations, and signal integrity limitations. [0005] The present invention is directed at overcoming, or at least improving upon, the disadvantages of the prior art.
