    摘要: A probe card for testing electronic elements includes a layer of dielectric material provided with a plurality of cavities supported on a substrate. A mass of fusible conductive material having a melting temperature below about 150° C. is disposed in each of said cavities, the dielectric material electrically insulating the masses of fusible conductive material from one another. A probe tip of conductive material having a melting temperature greater than about 150° C. is provided at one common end of each of the masses of fusible conductive material. The probe contacts are separated from an adjacent probe contact by at least one channel formed with the layer of dielectric material.

    摘要: A translator for connecting package terminals of a semiconductor chip package to connection pads on a substrate is disclosed. The package terminals are arranged in an array on the semiconductor chip package and the connection pads are arranged in an array on the substrate. The package terminals have a first pitch and the connection pads have a second pitch. The translator has a sheet-like support element with central region and a peripheral region which is more rigid than the central region. First translator terminals are exposed at a first surface of the support element, in the central region. Second translator terminals are exposed at a second surface of the support element, in the peripheral region. The first translator terminals have the first pitch so as to correspond to the package terminals and the second translator terminals have the second pitch so as to correspond to the connection pads. The first and second pitch are different. Traces are provided on the support element and are adapted to connect the package terminals to the first translator terminals.
