Hybrid interface apparatus for testing integrated circuits having both low-speed and high-speed input/output pins

Abstract

A hybrid interface apparatus including a fixed base including a contact-locking structure supporting several spring-based contact members, and a nesting member slidably positioned over the fixed base and having a central test area that includes an array of through-holes that are aligned with upper ends of the contact members. To facilitate testing of ICs including both relatively low-speed general-purpose I/O structures and new high-speed I/O structures, the contact members mounted on the contact structure include both low-cost, relatively high-inductance contact members for facilitating communication with the general-purpose I/O structures of the IC, and relatively expensive, low-inductance contact members for facilitating high-speed communications with the high-speed I/O structures of the IC.
