Tianyi Circuit Conductive Pen Silver Paste Ink Paint PVB Circuit Board Repair Conductive Silver Pen for Electronics PCB Trace Repair and Prototyping

The Tianyi Circuit Conductive Pen delivers professional-grade silver conductive ink for precise circuit board repairs, PCB trace restoration, and rapid prototyping. Formulated with high-purity silver paste suspended in a PVB (polyvinyl butyral) binder, this pen provides excellent adhesion to FR4, ceramic, glass, and flexible substrates. The fine-tip applicator enables accurate line drawing down to 0.5 mm width, making it ideal for repairing broken traces, creating jumpers, modifying prototypes, and bridging SMD pads. Fast-drying at room temperature with full conductivity achieved in minutes, it eliminates the need for soldering in many repair scenarios. Suitable for electronics technicians, hobbyists, engineers, and repair shops working on consumer electronics, automotive ECUs, industrial controls, and wearable devices. Each pen contains 2 ml of conductive silver ink with a shelf life of 12 months when stored properly.
