    PRODUCT DESCRIPTION
    CircuitWorks® Conductive Pen makes instant highly conductive silver traces on circuit boards. CW2200 is used in prototype, rework, and repair of circuit boards by linking components, repairing defective traces, and making smooth jumpers. The silver traces dry in minutes and have excellent adhesion to most electronic materials. Engineers, repair technicians, and manufacturers will find that the CircuitWorks® Conductive Pen speeds project completion and cuts rework time.

    COMPATIBILITY
    CircuitWorks® Conductive Pen material has excellent compatibility with materials used in printed circuit board fabrication. As with any chemical system, compatibility with the substrate must be determined on a non-critical area prior to use.
    USAGE INSTRUCTIONS
    Read MSDS carefully prior to use.
    Cleaning: For best adhesion, clean board with one of Chemtronics Electro-Wash® or Pow-R-Wash® solvents in order to remove any surface contamination which may prevent adequate material contact.
    Mixing: Although this system has been formulated to resist hard-packing, it should be shaken vigorously for 30 seconds to insure the proper dispersion of the silver flakes. If pen has been allowed to sit idle for a long period of time, the mixing ball may seize in the barrel. To free the ball use force to tap the barrel end of the pen until the ball begins to move inside the pen.
    Application: The conductive ink is dispensed through the CircuitWorks® Conductive Pen. Squeezing the pen body while pressing down on the surface will allow the material to flow, enabling the trace to be drawn. Practice with the pen before attempting detail work. The bulk form of this material may be applied by brushing, banding, or automatic dispensing equipment.
    Thinning: The conductive ink has been optimized for the CircuitWorks® Conductive Pen and thinning is not normally necessary. However, Butyl Acetate may be added with thorough mixing to make slight adjustments for ease of application in the bulk form.
    Clean-up/Removal: The conductive ink may be cleaned or removed using a strong organic solvent such as Chemtronics® Electro-Wash® PX.
    Curing: Tack-free in 3 to 5 minutes at room temperature. Achieves electrical conductivity within 30 minutes. Heat cure for 5 minutes at 250 to 300°F (120 to 150°C) for maximum conductivity, durability and chemical resistance.
    Soldering: Low temperature soldering is possible to the heat-cured silver conductive traces if done at 350°F (177°C) for <5 seconds.
