Besides the classical application of legend inks, marking components on a board for assembly or re-work, special notation inks can be used as reflecting layers for LED on rigid and flexible PCB’s. Our product offer is manifold from different color adjustments to photoimageable types for dense circuits. New especially white marking inks are optimized to cope with lead-free soldering. They show no yellowing even after multiple reflow cycles.
