1.5mm FR4 UL 94V0 PCB HDI Circuit Board For Power Electronic Automotive

High Quality 94V0 HDI Circuit Board for Power Electronic

♦ What is 94V0 PCB?

A ​​94V0 PCB​​ refers to a ​​printed circuit board (PCB)​​ that meets the ​​UL 94V-0 flammability standard​​, meaning it has high fire resistance and self-extinguishing properties. This rating is crucial for ensuring safety in electronic devices, particularly those used in high-temperature or high-risk environments.

♦ Key Features of a 94V0 PCB:​

1. 1. ​​Flame Resistance​​

      • When exposed to fire, a 94V0 PCB will ​​stop burning within 10 seconds​​ after the flame is removed.
      • It does ​​not drip flaming particles​​ that could spread fire.

   2. ​​Material Composition​​

      • The PCB substrate (usually ​​FR-4​​) is treated with flame-retardant additives (e.g., brominated compounds) to achieve the 94V0 rating.
      • The copper layers and solder mask do not significantly affect the flammability rating.

   3. ​​Compliance with UL 94 Standard​​

      • UL 94 is a ​​safety certification​​ by Underwriters Laboratories (UL) for plastic materials used in devices.
      • ​​V0​​ is the highest vertical burn rating (others include V1, V2, HB).

   4. ​​Applications​​

      • Used in ​​high-power electronics​​, power supplies, automotive systems, industrial controls, and consumer electronics where fire safety is critical.
      • Often required for ​​safety certifications​​ (e.g., CE, RoHS, UL).

♦ Why is 94V0 Important for PCBs?​

• • Prevents fires in case of electrical faults or overheating.
  • Meets ​​international safety standards​​ for electronics.
  • Reduces risk in applications like power adapters, LED lighting, and medical devices.
