    Abstract: A method of making a contact having a wear resistant edge by forming a photoresist layer on a copper clad polyimide composite structure, patterning the photoresist layer to expose a portion of the copper; etching the copper to form a contact and/or contact tabs having etched edges, and plating a wear resistant material on the etched edges. After the photoresist layer is stripped, the top portion of the contact and/or contact tabs are etched to height that is below the height of the wear resistant edge.

    Abstract: A connector for microelectronic elements includes electrically conductive, elongated leads having contact portions underlying a compliant layer. The contact portion of each lead overlies a pedestal portion of the compliant layer. The pedestal portion is at least partially isolated from the remaining portion of the compliant layer by gaps in the compliant layer. The pedestals may thus deflect horizontally, compensating for relative movement between the connector and the microelectronic element. Portions of the leads spanning the gaps may be curved to facilitate deflection. The pedestals may be attached to a substrate having terminals. A terminal end of each lead is then electrically connected to the terminal in the substrate, either through a plated through-hole, or by bending downward and bonding. The pedestals may support a plurality of leads along their length. Alternatively, the pedestals may support only a single respective lead, in which case the pedestal is isolated from neighboring pedestals and may deflect in a plurality of horizontal directions.

    Abstract: A testing fixture for microelectronic elements is in the nature of an interposer which is operative for receiving a plurality of test probes. The interposer enables the simultaneous testing of contacts on the microelectronic element which are arranged in both high contact pitch density areas and normal contact pitch density areas. The contacts on the microelectronic element within the high contact pitch density areas are accessed by conductive leads on the interposer having rigid portions arranged in a corresponding high contact pitch density.

    Abstract: A method of encapsulating a microelectronic assembly includes providing one or more microelectronic assemblies having one or more elements defining exterior surfaces and an array of terminals exposed at the exterior surfaces, the one or more elements defining one or more apertures through the exterior surfaces. A layer of a curable barrier material is then provided on a supporting element. The barrier layer has openings therein in a pattern corresponding to the array of terminals on the one or more microelectronic assemblies. The supporting element and the one or more microelectronic elements are then assembled together so that the layer of barrier material contacts the exterior surfaces and covers the apertures and so that the openings in the layer of barrier material are aligned with the terminals. The barrier material is then cured while in contact with the exterior surfaces to thereby form a barrier layer covering the apertures. Next, a curable liquid encapsulant is applied to the microelectronic assemblies, whereby the barrier layer prevents the curable liquid encapsulant from flowing through the apertures, and the encapsulant is cured. The barrier layer and the supporting element cooperatively surround the terminals exposed at the exterior surfaces to protect the terminals from contaminants.
