Conductive Silver Pen

EMS #12644

Use the Conductive Pen to draw precise, highly conductive silver traces, jumpers and shielding. Draw on conductive silver pathways, repair damaged circuit traces and apply smooth jumpers in electronic applications where heat curing is not desirable. The Conductive Pen dries at room temperature, or can be heat cured for maximum performance. Safe for use with common circuit materials, the Conductive Pen can be applied over metal, glass, solder mask, and both rigid and flexible surfaces. Air-dried, it’s ideal for electronic prototype, manufacturing and repair applications where heat curing is not desirable.


Make sure surface to be repaired is clean and free of oil.

Shake the pen VIGOROUSLY for 20-30 seconds to mix the conductor. Note: Pen’s internal shaker balls assist in mixing silver particles.

Press the pen lightly against the surface to be repaired. Squeeze the pen barrel firmly to start and then regulate the conductor’s flow. Practice with pen before working on the repair. If clogged, remove pen tip by turning it clockwise and clean.

Allow to dry for five to ten minutes. Air cure conductivity is reached in 20-30 minutes. Heat cure in 3-5 minutes at 250-300°F for maximum conductivity.

Wipe pen tip clean after use.

Use Procedures

Drying : Air dry in 3-5 minutes at room temperature. Maximum air dry conductivity after 20-30 minutes. Heat cure in 3-5 minutes at 250-300°F (121-148°C) for maximum conductivity.

Soldering : 350°F(176°C) for<5 seconds after heat cure. Use low temperature solder and a low temperature soldering iron for best results. Hand soldering at higher temperatures is not recommended.

Traces : Standard tip traces as narrow as 1/26” in width.

Amount : Approximately 100 feet of conductive repairs, jumpers and shielding

Shelf Life : Six months from first use. Unopened shelf life is 18 months from manufacture.

WARNING : FLAMMABLE. Keep away from sparks or open flame. DO NOT TAKE INTERNALLY. Avoid prolonged breathing of vapor. Use only in well ventilated area. HARMFUL OR FATAL IF SWALLOWED. Additional technical sheets and/or Material Safety Data Sheets are available on request.
