Publication number: 20240377436Abstract: A tunnel-type probe includes a tube, an elastic member, and a pin. The elastic member is assembled in the tube. The pin is movably disposed through the tube, and is electrically coupled to the tube by being connected to the elastic member. The pin has an inner segment, a contacting segment, and a limiting segment, the latter two of which are connected to two ends of the inner segment. The inner segment is arranged in the tube and is connected to the elastic member. The contacting segment and the limiting segment are respectively located at two opposite sides of the tube. When the tunnel probe abuts against a device under test (DUT) through the contacting segment, the pin is moved in a direction away from the DUT, such that the elastic member is deformed from being pressed by the pin so as to generate an elastic force.Type: ApplicationFiled: April 11, 2024Publication date: November 14, 2024Inventors: YU-JU LU, YI-HSIEN CHEN, MENG-CHIEH CHENG, WEI-JHIH SU

Publication number: 20240377437Abstract: An open-type probe of a vertical probe card includes a frame, an elastic member, and a pin. The frame has an operation slot and two lateral openings being in spatial communication with the operation slot. The elastic member is assembled to the frame and is located in the operation slot. The pin includes an inner segment assembled in the operation slot and a contacting segment that protrudes from an opening of the operation slot. The pin abuts against the elastic member through the inner segment so as to be electrically coupled to the frame. The elastic member and the inner segment are arranged between the two lateral openings. The contacting segment is configured to abut against a device under test, so that the contacting segment is moved toward the operation slot to press the elastic member for deforming the elastic member to generate an elastic force.Type: ApplicationFiled: April 11, 2024Publication date: November 14, 2024Inventors: YU-JU LU, YI-HSIEN CHEN, MENG-CHIEH CHENG, WEI-JHIH SU
