The 841AR-P Conductive Pen dispenses an acrylic lacquer pigmented with conductive nickel flakes.  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 repairs damaged traces on keyboards, game controllers, remote controls, mixing boards, and PCBs. It also creates conductive traces for prototyping, hobbies, or maker projects. It is great for making small connections in or between circuits, such as jumpers, through-holes, bridges, and links. It can also be used to increase the surface area of contacts by painting the areas around them.

For applications requiring lower resistance, use the 842AR-P Silver Conductive Pen. For a more economical alternative, use the 838AR-P Carbon Conductive Pen.
