  • Method of coating printed circuit board
    Patent number: 6389690
    Abstract: A conformal coating and method for applying same to a printed electrical circuit board, components and leads for providing corrosion resistance. In a preferred embodiment, the conformal coating comprises a first coating layer of parylene which is vacuum deposited and removably bonded onto an ultra-clean surface of a printed circuit board including attached components and leads. Additionally, a second coating layer of a corrosion inhibiting viscous fluid is deposited onto the first coating layer to form a continuous, stratified, conformal coating which is sealed and corrosion resistant.
    Type: Grant
    Filed: April 19, 1999
    Date of Patent: May 21, 2002
    Assignee: American Meter Company
    Inventors: Randy L. McCullough, John Lee Wayt, James N. Butch
