94V-0 on a flexible circuit board refers to a UL flammability rating that measures how resistant the board’s material is to fire. When a flexible PCB is labeled as 94V-0, it means the substrate has passed the UL 94 vertical burn test, proving that it can self-extinguish within 10 seconds after flame exposure and does not produce flaming drips. In short, a 94V-0 flexible circuit board is a flame-retardant FPC designed to meet the highest safety requirements in electronic manuf

Achieving precise flexible PCB impedance control is essential in flexible circuit design. Because FPCs are thin and flexible, even small changes in dielectric thickness, copper, or trace shape can mess with the signals. Keeping impedance under control helps things run smoothly and signals stay clean. Flexible PCB Impedance Control in Design The foundation of stable impedance starts with careful design. Trace Width (W): Wider traces reduce impedance, while narrower traces incr
