838AR-P - Carbon Conductive Pen

A circuit repair pen that dispenses acrylic lacquer pigmented with conductive carbon. The cured traces are durable and corrosion resistant, with fair conductivity. They adhere well to plastics and most electronics substrates. The valve tip opens when pressed against a surface, and the flow is controlled by squeezing the barrel. The product works best on a smooth, flat, hard surface, but the cured traces are highly flexible.

This circuit pen fixes damaged traces on keyboards, game controllers or remote controls. It is also useful for making small connections, such as jumpers and bridges. It is great for drawing resistors and can be used to increase the surface area of contacts by painting the area around them.

This pen is for low voltage or digital applications. For applications requiring lower resistance, use the 841AR-P Nickel Conductive Pen or the 842AR-P Silver Conductive Pen. This product is also available in liquid and aerosol formats.
