MG Chemicals 841AR-P, Nickel Conductive Pen, 5ml Pen, Case of 5

This nickel conductive pen is a circuit board trace repair pen that dispenses acrylic lacquer pigmented with conductive nickel flakes. The cured traces are durable, corrosion resistant, and have good 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 trace pen fixes 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 traces, such as jumpers, through-holes, and bridges. It can also be used to increase the surface area of contacts by painting the areas around them.
