CircuitWriter Pen, 4g

Precision Pen, fast drying formula, silver-based

Precision Conductive Ink applies instant traces on most surfaces (epoxy, glass, plastic, metal).

Draw traces on circuit boards, repair defective traces, make jumpers and shield electronics, design prototype circuits and repair rear-window heater traces.

  • Excellent adhesion
  • Good abrasion resistance
  • Low electrical resistance
  • Dries in minutes at room temperature to a highly conductive flexible coating
  • Apply to both rigid and flexible materials with excellent adhesion
  • Makes instant traces on most surfaces

Directions for Use:

  1. Turn off, unplug the device.
  2. PREPARE SURFACE. Remove loose scale, oil, grease, and dirt from surface.
  3. SHAKE WELL. Shake for at least 10 seconds. Shaker ball inside will assist mixing of materials. If necessary, clean tip with tissue or other soft cloth to remove dried material.
  4. APPLY. Squeeze the pen barrel while pressing the pen tip lightly on surface. Practice on scrap piece before attempting prototype or repairs. If tip gets clogged, remove pen tip (turn clockwise) and clean.
  5. DRY. Allow approximately 24 hours to dry at room temperature (70F). Recommend curing 6” away from a 40 watt light bulb for 4 hours. Then let sit overnight.
  6. CLEAN UP. Acetone or other suitable solvent.
