  • System and method for making printed electronic circuits using electrophotography
    Publication number: 20070234918
    Abstract: A method and system are provided for printing an electronic device onto a substrate using electrophotography (EP). The method includes generally three steps. First, a surface is provided, such as a substrate (e.g., paper, plastic film, etc.) on which the electronic device is to be printed. Second, the surface is routed through a sequential series of EP print stations. Each of the EP print stations consists of an electrostatically chargeable drum or plate and at least a portion of one surface support structure (e.g., a transfer roller, platen, etc.), wherein each electrostatically chargeable drum or plate defines a positive image formed of charged particles. Third, the positive images defined on the electrostatically chargeable drums or plates of the series of EP print stations are sequentially transferred onto the surface. Each of the positive images represents an image layer for forming the electronic device.
