Abstract:
A split thin-film probe card and an elastic module thereof are provided. The elastic module includes an elastic cushion and a thin-film sheet. The elastic cushion has a plurality of partition slots so as to define a plurality of independent elastic segments. The thin-film sheet includes a carrier, a plurality of signal circuits disposed on the carrier, and a plurality of conductive protrusions that are respectively formed on the signal circuits. The carrier has a plurality of grooves so as to divide the carrier into a plurality of action segments respectively disposed on the independent elastic segments. The signal circuits are respectively disposed on the action segments. When any one of the conductive protrusions is pressed, only the corresponding independent elastic segment is deformed through the corresponding signal circuit and the corresponding action segment.
