94V0 is a flammability rating for printed circuit boards (PCBs) according to the UL 796 standard. It indicates that a circuit board has passed specific tests for flammability and will not easily catch fire in normal use. The rating is based on the results of tests such as glow wire ignition, vertical flame spread, and comparative tracking index.

Printed circuit boards (PCBs) are essential components in a wide range of electronic devices, from smartphones and laptops to medical equipment and industrial machines.

To ensure the safety and reliability of these products, manufacturers must use high-quality circuit boards that meet strict safety standards. One such standard is the UL 796 rating system, which assigns a flammability rating to PCBs based on their ability to resist fire. The 94V0 rating is one of the most common and sought-after flammability ratings in the electronics industry.
