Chemtronics CircuitWorks® Conductive Pens make instant highly conductive silver traces on circuit boards and are used in prototype, rework, and repair of circuit boards by linking components, repairing defective traces, making smooth jumpers. The silver traces of the circuit pen dry in minutes and have excellent adhesion to most electronic materials. Engineers, repair technicians, and manufacturers will find that the CircuitWorks® Conductive Circuit Pen speeds project completion and cuts rework time.
