  • Patent number: 12292456
    Abstract: A wedge amplitude-modulation probe card and a main body thereof. The probe card includes a probe card main body, upper wedge plates and lower wedge plates. Several upper wedge plates and several lower wedge plates are slidably arranged inside the probe card main body, and the several upper wedge plates and the several lower wedge plates are sequentially arranged at intervals in a staggered manner, so that by means of inserting different numbers of upper wedge plates between the lower wedge plates, probes on the upper wedge plates can be inserted into or shifted out of a probe queue thereunder, so as to increase or decrease the number of probes for testing, and thus, the testing amplitude of a single probe card can be adjusted, such that the probe card has universality.

  • Patent number: 12270830
    Abstract: The present invention relates to a method for realizing the measuring slip of membrane probe, wherein: an elastomer layer is placed between the rigid acting surface of the membrane probe head and the membrane on which the probe is arranged; on the axial plane of the probe, the elastomer layer takes any axial line passing through the probe as a boundary line, and there is a difference between the thickness of one side and thickness of the other side, so that the probe can deflect during the test, resulting in the measuring slip to penetrate or push away the surface oxide of the tested chip and achieve more stable contact.
