Abstract:
A contact structure for establishing electrical connection with contact targets, comprising:a probe card having a plurality of sockets and a plurality of contact pads and signal patterns for connecting the sockets and the contact pads where said contact pads are connected to mechanical contactors including pogo-pins when the contact structure is assembled; a plurality of contactors mounted on the probe card at about a center of the probe card in a manner that tips of the contactors are projected from one surface of the probe card to contact; and a flexible cable having a plurality of signal patterns for transmitting electrical signals therethrough, the flexible cable having the contactors at one end while being connected to the sockets on the probe card at another end; and wherein the flexible cable having the contactors are provided on one surface of the probe card and the tips of the contactors are inserted in the probe card and projected from another surface of the probe card, thereby obviating a substrate having signal patterns for space transforming.
