  • Publication number: 20240103042
    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. Compression of probe tips toward one another may cause portions of spring elements to move closer together or further apart.

  • Publication number: 20240094261
    Abstract: Probes for testing (e.g. wafer level testing or socket level testing) of electronic devices (e.g. semiconductor devices) and more particularly, arrays of such probes are provided. Probes are formed by initially fabricating probe preforms in batch with bases and/or ends located in array patterns, directly or indirectly on one or more build substrates with the arrayed preforms being in a longitudinally compressed state and whereafter the preforms are longitudinally plastically deformed to yield probes or partially formed probes with extended longitudinal lengths. Probes may be formed with deformable spring elements formed from one or more single layers which are joined by vertical elements located on other layers or they may be formed by spring elements that are formed as multi-layer structures. Arrays may include probe preforms with laterally overlapping or interlaced structures (but longitudinally displaced) which may remain laterally overlapping or become laterally displaced upon plastic deformation.

  • Publication number: 20240094255
    Abstract: Probes for contacting electronic components include a plurality of compliant modules stacked in a serial configuration, which are supported by an exoskeleton or an 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). Other probes are formed from single compliant modules or pairs of back-to-back modules that may share a common base. Module bases may include configurations that allow for one or both lateral alignment and longitudinal alignment of probes relative to array structures (e.g., array substrates, guide plates) or other modules they contact or to which they adhere.

  • Publication number: 20240085457
    Abstract: Embodiments are directed to probe structures, arrays, methods of using probes and arrays, and/or methods for making probes and/or arrays. In the various embodiments, probes include at least two springs separated by a movable stop while in other embodiments, three or more springs may be included with two or more movable stops. Movable stops interact with fixed stops that are either part of the probes themselves or part of separate elements that engage with the probes (such as array frame structures) that provide for the retention, longitudinal and/or lateral positioning of probes and possibly for orientation of the probes about a longitudinal axis. Fixed stops provide for controlled limits for movement of the movable stops which in turn allow for enhanced compliant or elastic performance of the probes upon increased probe compression in either one direction, in the order of tip compressions, or in both directions or tip compression orders (e.g.

  • Publication number: 20240061017
    Abstract: Probe arrays include spacers attached to the probes that were formed along with the probes. Methods of making probe arrays by (1) forming probes on their sides and possibly as linear arrays or combination subarrays (e.g. as a number of side-to-side joined linear arrays) having probes fixed in array positions by a sacrificial material that is temporarily retained after formation of the probes; (2) assembling the probe units into full array configurations using the spacers attached to the probes or using alternative alignment structures to set the spacing and/or alignment of the probe(s) of one unit with another unit; and (3) fixing the probes in their configurations (e.g. bonding to a substrate and/or engaging the probes with one or more guide plates) wherein the spacers are retained or are removed, in whole or in part, prior to putting the array to use.

  • Publication number: 20240019463
    Abstract: Forming buckling beam probe arrays having MEMS probes engaged with guide plates during formation or after formation of the probes while the probes are held in the array configuration in which they were formed is disclosed. Probes can be formed in, or laterally aligned with, guide plate through holes. Guide plate engagement can occur by longitudinally locating guide plates on probes that are partially formed or fully formed with exposed ends, by forming probes within guide plate through holes, by forming guide plates around probes, or forming guide plates in lateral alignment with arrayed probes and then longitudinally engaging the probes and the through holes of the guide plates. Arrays can include probes and a substrate to which the probes are bonded with one or more guide plates. Final arrays can include probes held by guide plates with aligned or laterally shifted hole patterns.
