Use this instrument on circuit boards to link components, make smooth jumpers, repair defective traces, and shield delicate electronics. Features a valve tip to control the flow of a polymer ink made with highly conductive silver. Dries in minutes at room temperature. Achieves maximum conductivity after 20 minutes, or after heat curing for 3-5 minutes at 250°F-300°F. You can solder at low temperatures (up to 350°F for 5 seconds) after ink dries completely. Pen can be used on flexible as well as rigid materials including keypads, circuit film, glass, and circuit board laminate. Also safe for use on solder, solder mask, copper and gold. Contains enough ink to make 150 feet of conductive traces. Choice of micro tip for fine lines or standard tip for wider lines.
