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. 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.
