Circuit Scribe Conductive Ink Pen

Product Information

Use to repair existing shielding damage, as a conductive undercoat when electroplating, to give you electric continuity of your circuits. Engineers, repair technicians, and manufacturers will find that the Circuit Works conductive pen speeds project completion, cuts down rework time and has excellent compatibility with materials used in printed circuit board fabrication. That’s why understanding the best rework and repair methods and materials is so important for those who manufacture, maintain, or repair printed circuit boar.

Make the pen body slightly vertical, press the pen tip lightly on the plane, squeeze the pen bar and drag slowly, and the handwriting needs to be plump and stable. It has a valve tip that opens when the pen is pressed against the surface to be drawn on and it has a soft tube, so the flow may be controlled by squeezing the center of the pen. A trace drawn with the conductive ink will combine with solder, provided the soldering temperature does not exceed 350 °F (177 °C) and the solder joint is formed within 5 seconds. You may need to clear the tip of dried ink with a wipe saturated with solvent like isopropyl alcohol (IPA). Chemtronics offers CircuitWorks® Conductive Pens, which contain a highly conductive material like silver or nickel suspended in a liquid polymer.The indicator for the ink level is a white ball that starts just before the first "e" in electroninks. For applications where high conductivity is not required, the 838AR-P Carbon Conductive Pen and the 841AR-P Nickel Conductive Pen provide economical alternatives.

We've measured the resistance of pencil traces at 5 - 8 megaohms with a single pass, and 30-60 kiloohms with lots of pressing down and scribbling. For functional use, photo paper performs the best because the ink is able to form a continuous film on a smooth surface. Soldering to the ink is possible, but tricky and greatly depends on paper/surface type and solder type.Techspray offers TraceTech Conductive Pen, which contains highly conductive silver suspended in a liquid polymer. Chemtronics offers CircuitWorks Conductive Pens which contain a highly conductive material like silver or nickel suspen. The CircuitWorks ® Conductive Pen is compatible with materials used in the fabrication of printed circuit boards. Safe and reliable, no welding required; easy to understand and easy to learn; fun and entertaining; diverse gameplay, wireless imagination!
