Publication number: 20200348338Abstract: A test pin contact buffer, fixed to a test pin base, is a sheet-like structure made of a composite material including a conductive material and an insulating material, and defines at least one contact area corresponding to at least one test pin of the test pin base. The contact area has at least one cutout hole, an insulating deformation structure and a conductive head structure. The insulating deformation structure is extendable and made of the insulating material and extends outward from the conductive head structure. The cutout hole enables the contact area to be in a partial hollow state, which is beneficial for deformation of the insulating deformation structure. The test pin can be used for performing measurement in an indirect manner, reducing the wear of the test pin, prolonging the service life, and improving the measurement speed and efficiency.Type: ApplicationFiled: April 30, 2019Publication date: November 5, 2020Inventors: MING-DAO WU, SHIH-HUNG LO, FU-CHENG CHUANG, ZHAO-YUAN TSAI, HAO-WEN CHIEN, BOR-CHEN TSAI, CHIH-FENG CHEN
