Abstract:
A stiffener for a probe card assembly can include decoupling mechanisms disposed within radial arms of the stiffener. The decoupling mechanisms can be compliant in a direction along a radial direction of said radial arm and rigid in a direction perpendicular to said radial arm. The decoupling mechanisms can decouple the stiffener from thermally induced differential radial contraction and expansion of the stiffener relative to the cardholder to which the stiffener is mounted. This can reduce thermally-induced vertical translation of the probe card assembly.
