Abstract: Probes for contacting electronic components include compliant modules stacked in a serial configuration, which are supported by a sheath, exoskeleton, or endoskeleton which allows for linear longitudinal compression of probe ends toward one another wherein the compliant elements within the compliant modules include planar springs (when unbiased). Alternatively, probes may be formed from single modules or back-to-back modules that may share a common base/standoff. Modules may allow for lateral and/or longitudinal alignment relative to array structures or other modules. Planar springs may be spirals, interlaced spirals having common or offset longitudinal levels, with similar or different rotational orientations that are functionally joined, and planar springs may transition into multiple thinner spring elements along their lengths. Compression of probe tips toward one another may cause portions of spring elements to move closer together or further apart.
