  • Patent number: 11536765
    Abstract: A probing apparatus includes a frame, a testing device, a rotatable testing platform, and a probe module. The testing device is disposed on the frame and is displaceable along an X direction and a Y direction perpendicular to the X direction. The rotatable testing platform is disposed on the frame and is rotatable around a rotating axis extending in the X direction. A direction perpendicular to the X direction and the Y direction is a Z direction, and the rotatable testing platform and the testing device are located at different positions of the Z direction. The probe module is disposed on the rotatable testing platform.

  • 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.
