  • Publication number: 20240241155
    Abstract: A probe card includes a structure stiffener unit including a base with a lower surface where central and peripheral supporting elements protrude out and a main circuit board is fixed, a space transformer and a probe head disposed thereunder, which are disposed to the supporting elements by bolts and defined with central and peripheral regions located correspondingly to the central and peripheral supporting elements respectively, and a metal supporting member fixed on the space transformer in a direct contact manner and located correspondingly to the central region. The supporting member has a lower surface coplanar with the lower end surface of the peripheral supporting element, which is abutted on the space transformer, and an upper surface against which the central supporting element is abutted. The space transformer has great structural strength, flatness and heat dissipation effect for satisfying the large-area requirement and great electrical property testing stability.

  • Patent number: 9525218
    Abstract: A conductive wire connection structure of rail-type electrical terminal is able to reduce the yield of waste material in manufacturing, enhance heat dissipation effect and increase operational and motional stability in condition of structural simplification. The conductive wire connection structure includes a conductive support mounted in an insulation case. The conductive support is divided into two parts of a U-shaped support main body and a C-shaped wire connector. The wire connector is assembled with a metal leaf spring and disposed on the support main body together with the metal leaf spring for pivotally connecting with the grounding conductive wire coming from an apparatus. The wire connector and the metal leaf spring are respectively formed with insertion sections for assembling the wire connector with the metal leaf spring to help the support main body to hold the metal leaf spring and prevent the metal leaf spring from deflecting.
