Abstract
A method of applying a conductive pattern of metal onto a web of indefinite length material. This method includes applying a metal containing composition onto the web in a predefined pattern, providing a roll having a very low thermal mass, and conveying the patterned web around the roll while simultaneously applying heat energy to the metal containing composition thereby converting the metal to a conductive pattern. This allows for flexible circuitry to be fabricated in an inexpensive roll-to-roll process.
