The CW2900 is a Flex Conductive Pen makes instant highly adherent silver traces on flexible polymeric substrates used in flex circuitry. It is used in prototype, rework and repair of Mylar®, Melinex® and other flexible circuits by linking components, repairing defective traces and making smooth jumpers. The flex conductive pen traces also have excellent adherence to indium tin oxide (ITO) substrates. The silver traces dry in minutes and have excellent mechanical properties. Silver filled polymer material with silver grey colour. The CircuitWorks® flex conductive pen material has excellent compatibility with materials used in flexible circuit board fabrication. As with any chemical system, compatibility with the substrate must be determined on a non-critical area prior to use.
