  • Patent number: 11499991
    Abstract: The present disclosure relates to an IC chip holder capable of alleviating an impact if the IC chip holder is dropped or collides with another object. In the IC chip holder, an upper housing body is provided, on a side of electric contacts of an IC chip, with an elastic deformation portion capable of elastically deforming toward the inside of the upper housing body. Thus, since the elastic deformation portion elastically deforms toward the inside of the upper housing body, if the IC chip holder is dropped or collides with another object, the elastic deformation portion bends and the impact is alleviated. Thus, a possibility of the IC chip being damaged is reduced.

  • Patent number: 11486898
    Abstract: Vertical transmission line probes having alternating capacitive and inductive sections are provided. These alternating sections can be designed to provide a desired transmission line impedance (e.g., between 10 and 100 Ohms, preferably 50 Ohms). Probe flexure in operation is mainly in the inductive sections, advantageously reducing flexure stresses on the dielectrics in the capacitive sections.

  • Patent number: 11480589
    Abstract: Integrating a bracket with planarity adjustment holding a wafer probe securely, with a low-profile impedance tuner that is mounted on a 3-axis tuner positioner under an angle matching the angle of the wafer probe. The low-profile tuner has its tuning probe operating as close as physically possible within the distance of an RF adapter from the wafer-probe and is connected directly with the wafer-probe. This integration offers the maximum possible tuning range, while simultaneously offering planarity (THETA) control. It also eliminates the need for an extension RF cable between the instrument (tuner) and the wafer-probe, including a set of two coaxial adapters.

  • Patent number: 11460498
    Abstract: An adjustable probe device includes fixed and movable probes, at least one of which is a signal probe having a coaxial structure. The movable probe is linearly slidable with a ground unit thereof abutted against a ground unit of the fixed probe. Another adjustable probe device includes a first movable probe for being grounded, and fixed and second movable probes both having a coaxial structure. Any of the two movable probes is selectable to be a functioning probe in a way that the contact ends of the functioning and fixed probes are located on a same plane for contacting two pads of a DUT at the same time, and the functioning probe is linearly slidable with a ground unit thereof abutted against a ground unit of the fixed probe. As a result, the probe interval is adjustable, lowering the cost of the impedance testing apparatus for circuit boards.

  • Patent number: 11402408
    Abstract: An electrical characteristics inspection tool capable of inspecting electrical characteristics even when an oxide film is formed on pads or bumps formed at a fine pitch. The electrical characteristics inspection tool includes: a flexible sheet; a through electrode having a recess that is recessed from one surface of the flexible sheet; and a conductive elastomer disposed in the recess of the through electrode. Electrical characteristics can be inspected even when an oxide film is formed on pads or bumps of an inspection object by bringing the conductive elastomer into contact with the pads or bumps and bringing a probe into contact with the through electrode since the conductive particles in the conductive elastomer break through the oxide film.
