Patent number: 11933817Abstract: 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.Type: GrantFiled: January 13, 2022Date of Patent: March 19, 2024Assignee: CHUNGHWA PRECISION TEST TECH. CO., LTD.Inventors: Wen-Tsung Lee, Hsun-Tai Wei, Pang-Chi Huang, Meng-Chieh Cheng
