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. to provide one or more decreases in spring constant upon reaching one or more compression levels (or biasing force levels) with a given tip compression direction and/or order).
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.

Abstract:
Probe array for contacting electronic components includes a plurality of probes for making contact between two electronic circuit elements and an array plate mounting and retention configuration. The probes may comprise lower retention features that protrudes from a probe body with a size and configuration that limits the longitudinal extent to which the probes can be inserted into plate probe holes of an array plate and an upper retention feature having a lateral configuration that is sized to pass through the extension provided by the side wall feature of the plate probe hole when aligned and after longitudinally locating the upper retention feature above the extension, the retention feature undergoes displacement relative to the upper plate probe hole such that the upper retention feature can no longer longitudinally pass through the extension of the upper plate probe hole.

Abstract:
Some embodiments are directed to techniques for building single layer or multi-layer structures on dielectric or partially dielectric substrates. Certain embodiments deposit seed layer material directly onto substrate materials while others use an intervening adhesion layer material. Some embodiments use different seed layer and/or adhesion layer materials for sacrificial and structural conductive building materials. Some embodiments apply seed layer and/or adhesion layer materials in what are effectively selective manners while others apply the materials in blanket fashion. Some embodiments remove extraneous material via planarization operations while other embodiments remove the extraneous material via etching operations. Other embodiments are directed to the electrochemical fabrication of multilayer mesoscale or microscale structures which are formed using at least one conductive structural material, at least one conductive sacrificial material, and at least one dielectric material. In some embodiments the dielectric material is a UV-curable photopolymer.
