  • Miniaturized contact spring
    Patent number: 7137830
    Abstract: This invention provides a solution to increase the yield strength and fatigue strength of miniaturized springs, which can be fabricated in arrays with ultra-small pitches. It also discloses a solution to minimize adhesion of the contact pad materials to the spring tips upon repeated contacts without affecting the reliability of the miniaturized springs. In addition, the invention also presents a method to fabricate the springs that allow passage of relatively higher current without significantly degrading their lifetime.
    Type: Grant
    Filed: March 17, 2003
    Date of Patent: November 21, 2006
    Assignee: NanoNexus, Inc.
    Inventors: Syamal Kumar Lahiri, Frank Swiatowiec, Fu Chiung Chong, Sammy Mok, Erh-Kong Chieh, Roman L. Milter, Joseph M. Haemer, Chang-Ming Lin, Yi-Hsing Chen, David Thanh Doan
