About Extended Length Flex

Developer of a core proprietary technology is called Plateable Toner Technology (PTT). PTT is a method of replacing conventional flexible circuits and round wire harnesses with printed harnesses. PTT uses a proprietary toner, similar to toner found in conventional xerographic copiers and laser printers, to transfer circuit images to plastic sheets. The toner facilitates the plating of copper to form the circuit. The unique properties of the plateable toner are maintained through the electrophotographic process, resulting in catalytically active patterns on the substrate. The first application of the technology is to manufacture a direct replacement for flexible circuits. The major market focus, however, is to produce extended length flexprint (ELF) as a replacement for conventional wiring harnesses. Large circuits, currently too large for conventional circuit printing processes, may be created by using large format and reel-to-reel copiers and printers. Relative to methods currently in use, the PTT method of creating printed circuitry requires fewer steps, produces patterns of unlimited size, and generates a relatively small amount of waste.
