Patent ID: 7135203

Claim:
A continuous reel-to-reel printing process for selectively forming a thin conductive polymer coating on at least a portion of a non-critical region of a plurality of flexible circuits comprising: providing a roll of interlever material and a roll of flexible circuits having multiple circuits positioned across a transverse width of the roll in a row, and a plurality of rows positioned along a longitudinal direction of the roll, unwrapping the interlever material from the roll onto a web, moving the web and the interlever material at a set speed in a web direction to pass by the roll of flexible circuits, feeding the flexible circuits off the roll at the same speed in the web direction while maintaining a web tension by means of a plurality of idler rolls, moving the web into a printing station, applying a conductive polymer composition by means of a transfer printing technique to at least a portion of The non-critical area of the flexible circuits in a transverse manner across one row of flexible circuits, moving the web a prescribed interval in the web direction, repeating the printing step on the adjacent row of flexible circuits, repeating the printing step a prescribed intervals such that each row is printed, and moving the web into a drying oven.
