A probe card and a probe module thereof are provided. The probe card includes a first strengthening board, a fixed frame, a probe module, and a slidable frame. The first strengthening board includes a top surface, a bottom surface, and a mounting hole. An inner wall of the mounting hole is formed with an inner flange. The fixed frame is disposed on the top surface of the first strengthening board and surrounds the mounting hole. The probe module is disposed in the mounting hole and includes an outer flange including a physical region and multiple gap regions. The physical region abuts against the inner flange of the first strengthening board. The slidable frame is disposed on an inner wall of the fixed frame and is slidable between a released position and a fixed position. Multiple pressing portions are disposed on an inner wall of the slidable frame.

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.
