  • Publication number: 20220236304
    Abstract: Vertical probe arrays having angled guide plates are provided. With this configuration, the probes can be straight conductors (when mechanically undeformed) and the mechanical bias provided by the angled guide plates can ensure the probes have a well-defined deformation when the probe array make contact to the device under test. This allows the use of straight conductors as probes without suffering from probe shorting and mechanical interference caused by straight probes buckling in unpredictable directions when vertically compressed.

  • Patent number: 7808260
    Abstract: A probe configured for use in the testing of integrated circuits includes a first end portion terminating in a foot (42), the foot defining a substantially flat surface configured to be connected to a substrate (400), a second end portion terminating in a tip (50), the tip being configured to contact an integrated circuit during testing of the integrated circuit, and a curved body portion (56) extending between the first end portion and the second end portion.

  • Patent number: 7679383
    Abstract: A method and apparatus for a flattened probe element wire is provided. A probe element wire includes a beam portion and a tip portion. At least a part of the tip portion is flattened. Flattened probe element wires may have greater z-direction height strength, thereby increasing maximum probe element wire z-direction vertical force. Flattened probe element wires may also have decreased variability in the flattened probe element wire tips. A probe card assembly may includes a substrate and a plurality of at least partially flattened probe element wires supported by the substrate. Such probe card assemblies may have an extended life and maintained within design parameters for a longer period of use.
