Patent ID: 10120020

Abstract:
Probe head assemblies and probe systems for testing integrated circuit devices are disclosed herein. In one embodiment, the probe head assemblies include a contacting structure and a space transformer assembly. In another embodiment, the probe head assemblies include a contacting structure, a suspension system, a flex cable interface, and a space transformer including a space transformer body and a flex cable assembly. In another embodiment, the probe head assemblies include a contacting structure, a space transformer, and a planarization layer. In another embodiment, the probe head assemblies include a contacting structure, a space transformer, a suspension system, a platen, a printed circuit board, a first plurality of signal conductors configured to convey a first plurality of signals external to the space transformer, and a second plurality of signal conductors configured to convey a second plurality of signals via the space transformer. The probe systems include the probe head assemblies.
