Abstract
A flexure band can comprise structures configured to have elastic properties. Such a band can be stretched but will return generally to its original shape after forces that stretched the band are removed. The flexure band can hold one or more temperature control devices against a peripheral edge of a stiffening frame in a probe card assembly, or the flexure band can itself be a temperature control device. The band can be made of a metal that can be selected to impart one or more of the following properties: low thermal conductivity, high specific heat, generates little to no appreciable contamination, and/or usable over a wide range of temperatures. A material can be added to the band as a full or partial coating that enhances or adds one or more of the above-mentioned possible properties of the metal band.
