Description

ABSTRACT:
There is disclosed a coordinate transformation device for electrical signal connection used for a probe card applicable to narrow pitch pads, which particularly simplifies wiring from the terminal onto the inspection apparatus board and prevents electrical contact failure. In the coordinate transformation device for electrical signal connection, an input terminal of a first wiring group corresponding to one of probe output terminals is provided with at least two terminals independently movable in a yz plane. When the probe output terminal and the input terminal of the first wiring group are contacted and conducted with each other, a wall surface of a first terminal of the input terminal of the first wiring group comes into contact with a side wall of the probe output terminal, and a wall surface of a second terminal thereof comes into contact with a side surface on the opposite side of the probe output terminal.
