CircuitWorks Conductive Pens
CircuitWorks® Conductive Pens make instant highly conductive silver traces on circuit boards and are used in prototype, rework, and repair of circuit boards by linking components, repairing defective traces, making smooth jumpers. The silver traces of the circuit pen dry in minutes and have excellent adhesion to most electronic materials. Engineers, repair technicians, and manufacturers will find that the CircuitWorks® Conductive Circuit Pen speeds project completion and cuts rework time.
CircuitWorks Conductive Pens are available in 3 types of inks:
- Silver Conductive Pen (CW2200STP, CW2200MTP): Highly conductive and the most popular option. Available with either the standard tip (CW2200STP) or micro tip (CW2200MTP).
Conductivity - 0.02-0.05 ohms/sq/mil
- Silver Flex Conductive Pen (CW2900): Also silver-based, and engineered for flexible PCBs. Only available with the standard tip.
Condictivity - 0.05-0.15 ohms/sq/mil
- Nickel Conductive Pen (CW2000): Lower cost nickel-based ink. Only available with the standard tip.
Conductivity - 1.0 – 1.5 ohms/sq/mil

How do you repair a broken trace on a PCB?
A common method of repairing a broken trace is to solder on a jumper, which is basically a wire bypass around the broken trace. This can be time-consuming and visually unappealing. Chemtronics offers CircuitWorks® Conductive Pens, which contain a highly conductive material like silver or nickel suspended in a liquid polymer. These pens allow you to literally redraw the trace.
How do I figure out the shelf life of a product?
The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). The COC can be downloaded by going to https://www.chemtronics.com/coc. Once you have the shelf life, you will need to add it to the manufacture date for a use-by date. The manufacture date can be identified by the batch number. The batch code used on most of our products are manufacture dates in the Julian Date format. The format is YYDDD, where YY = year, DDD = day. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. This webpage explains and provides charts to help interpret our batch numbers: https://www.chemtronics.com/batch-codes.
