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.

Probing apparatus

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.

Adjustable probe device for impedance testing for circuit board

An electrical testing device includes a base having two parallel first rails, a platform provided on the base, a support provided between the first rails, a test arm, a rotary table provided on the test arm, a plurality of holders provided on the rotary table, and a plurality of probe sets respectively provided on the holders. The support has a second rail provided thereon, and is moveable relative to the base and the platform. The test arm is provided on the second rail and above the platform, wherein the test arm is moveable along with the support, and is also movable relative to the support. The rotary table is moveable or rotatable relative to the test arm. The holders are moveable along with the rotary table, and are also moveable or rotatable relative to the rotary table. The probe sets are moveable along with the holders.
