  • Patent number: 11933817
    Abstract: A probe card device and a transmission structure are provided. The transmission structure includes a supporting layer, a plurality of metal conductors spaced apart from each other and slantingly inserted into the supporting layer, and an insulating resilient layer formed on the supporting layer. Each of the metal conductors includes a positioning segment held in the supporting layer, a connecting segment and an embedded segment respectively extending from two ends of the positioning segment, and an exposed segment extending from the embedded segment. Each of the embedded segments is embedded and fixed in the insulating resilient layer, and each of the exposed segments protrudes from the insulating resilient layer. When any one of the exposed segments is pressed by an external force, the insulating resilient layer is configured to absorb the external force through the corresponding embedded segment so as to have a deformation providing a stroke distance.

  • Patent number: 11287446
    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.

  • Publication number: 20220018876
    Abstract: A probe card device and a fence-like probe thereof are provided. The fence-like probe includes a stroke segment, a fan-out segment, and a testing segment. The stroke segment is in an elongated shape defining a longitudinal direction, and the stroke segment has two end portions and a plurality of penetrating slots that are arranged along a fan-out direction perpendicular to the longitudinal direction, so that the stroke segment is deformable to store an elastic force by being applied with a force. The fan-out segment and the testing segment are respectively connected to the two end portions of the stroke segment. The fan-out segment has a fixing point arranged away from the stroke segment, and the testing segment has an abutting point arranged away from the stroke segment. Along the fan-out direction, the fixing point is spaced apart from the abutting point by a fan-out distance.

  • Publication number: 20220011346
    Abstract: A probe card device and a fan-out probe thereof are provided. The fan-out probe includes a stroke segment, a fan-out segment, and a testing segment. The stroke segment is in a straight shape defining a longitudinal direction, and the stroke segment has two end portions. The stroke segment is bendable when the two end portions are respectively applied with forces along two opposite directions. The fan-out segment and the testing segment are respectively connected to the two end portions of the stroke segment. The fan-out segment has a fixing point arranged away from the stroke segment, and the testing segment has an abutting point arranged away from the stroke segment. Along a fan-out direction perpendicular to the longitudinal direction, the fixing point is spaced apart from the abutting point by a fan-out distance.

  • Patent number: 11209461
    Abstract: A probe card device and a neck-like probe thereof are provided. The neck-like probe includes a conductive pin and a ring-shaped insulator. The conductive pin includes a stroke segment and two end segments extending from the stroke segment. The stroke segment has two broad side surfaces and two narrow side surfaces, and each of the broad side surfaces has a long slot extending from one of the narrow side surfaces to the other one. The two long slots have a minimum distance therebetween that is 75%-95% of a maximum distance between the two broad side surfaces. The ring-shaped insulator surrounds a portion of the conductive pin having the two long slots, and a portion of the neck-like probe corresponding in position to a part of the ring-shaped insulator on the two broad side surfaces has a thickness that is 85%-115% of the maximum distance.
