    Abstract: Contact tip structures are fabricated on sacrificial substrates for subsequent joining to interconnection elements including composite interconnection elements, monolithic interconnection elements, tungsten needles of probe cards, contact bumps of membrane probes, and the like. The spatial relationship between the tip structures can lithographically be defined to very close tolerances. The metallurgy of the tip structures is independent of that of the interconnection element to which they are attached, by brazing, plating or the like. The contact tip structures are readily provided with topological (small, precise, projecting, non-planar) contact features, such as in the form of truncated pyramids, to optimize electrical pressure connections subsequently being made to terminals of electronic components. Elongate contact tip structures, adapted in use to function as spring contact elements without the necessity of being joined to resilient contact elements are described. Generally, the invention is directed to making (pre-fabricating) relatively ‘perfect’ contact tip structures (“tips”) and joining them to relatively ‘imperfect’ interconnection elements to improve the overall capabilities of resulting “tipped” interconnection elements.

    Abstract: A wafer test assembly includes multiple probe head substrates arranged like tiles with connectors attached to one side and probes supported on the opposing side. In one embodiment, flexible cable connectors directly connect the connectors on the probe head tile to a test head, while in another embodiment the flexible cables connect the probe head tile to a PCB providing horizontal routing to test head connectors. In one embodiment, leveling pins provide a simplified support structure connecting to a retaining element attached to the tiles to provide for applying a push-pull leveling force. A test head connector interface frame enables rearrangement of connectors between the test head and the probe card to provide for both full wafer contact or partial wafer contact. The test head connectors are rearranged by being slidable on rails, or pluggable and unpluggable enabling movement over a range of positions.

    Abstract: Probes of a probe card assembly can be adjusted with respect to an element of the probe card assembly, which can be an element of the probe card assembly that facilitates mounting of the probe card assembly to a test apparatus. The probe card assembly can then be mounted in a test apparatus, and an orientation of the probe card assembly can be adjusted with respect to the test apparatus, such as a structural part of the test apparatus or a structural element attached to the test apparatus.

    Abstract: Methods are provided for making plated through holes usable for inserting and attaching connector probes. In a first method, a curved plated through hole is formed by bonding curved etchable wires to a first substrate, plating the wires with a non-etchable conductive material, encasing the plated wires with a dielectric material to form a second substrate, planing the second substrate to expose the etchable wire, and etching the wires to leave plated through holes. In a second method, wires coated with a first etchable layer are initially bonded to a substrate, a second non-etchable plating layer is then applied over the first layer, and the first layer is etched away leaving plated through holes with wires disposed inside. In a third embodiment, a layer of masking material is initially deposited on a substrate and etched to form holes which are filled with a sacrificial fill material, the masking material is then removed, the fill material plated, grinding is performed to remove some plating to expose the fill material, and the fill material is then etched away leaving plated attachment wells. Probes may be attached to the plated through holes or attachment wells to create resilient spring contacts to form a wafer probe card assembly. A twisted tube plated through hole structure is formed by supporting twisted sacrificial wires coated with the plating material in a substrate, and later etching away the wires.
