The 838AR-P Conductive Pen dispenses an acrylic lacquer pigmented with conductive carbon. The cured traces are durable and corrosion resistant. They adhere well to plastics and most electronics substrates. The traces are flexible, but the product works best on a smooth, flat, hard surface. The valve tip opens when pressed against the surface, and the flow is controlled by squeezing the barrel.

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

Use this pen when high conductivity is not required. For applications requiring lower resistance, use the 841AR-P Nickel Conductive Pen or the 842AR-P Silver Conductive Pen.
