Described herein is a probe card assembly providing signal paths for conveying high frequency signals between bond pads of an integrated circuit and an IC tester. If desired, one or more anchor may be used. Additionally, the present system supports newly-created frames as well as the concept of flushing the system without regard to frame order whereby frames are sent out to the network as the processing is completed without regard to input order, overriding the system of putting the output frames in the same order as the input frames were received from the network. The receiving portion is slidably movable relative to the bracing member in the longitudinal direction. A substrate cutting apparatus is equipped with the scribing apparatus, and a substrate cutting method uses the substrate cutting apparatus.
