A 94v0 circuit board is a type of Printed Circuit Board (PCB) that has been tested and certified under the UL 94V-0 Flammability Standard. This means it’s designed to stop burning within 10 seconds after being ignited, with no flaming drips allowed. These boards are crucial in the manufacturing of electronic devices, offering durability, temperature control, and the ability to withstand harsh environments. Their application ranges from simple electronic devices to complex machinery, making them a fundamental component in the electronics industry.
What is a 94v0 Circuit Board?
In the realm of electronics, the term ’94v0′ might sound technical and intimidating. However, once you break it down, it’s quite straightforward. The ’94v0′ in a 94v0 circuit board refers to a flammability standard set by Underwriters Laboratories (UL), a global safety certification company. This standard, known as the UL 94V-0 Flammability Standard, is a measure of how a material responds to fire or ignition sources.
| Flammability Rating | Burn Time | Flaming Drips Allowed? |
|---|---|---|
| 94V-0 | <10s | No |
| 94V-1 | <30s | Yes |
| 94V-2 | <60s | Yes |
When a circuit board is labeled as ’94v0′, it means that the board’s materials have undergone and passed the UL 94V-0 flammability test. In this test, the material is ignited, and its burning characteristics are observed. A 94v0 rating indicates that the material will cease to burn within 10 seconds after being ignited, with no flaming drips allowed. This makes 94v0 circuit boards highly desirable in electronic manufacturing, as they add an extra layer of safety against potential fire hazards.
But a 94v0 circuit board isn’t just about fire safety. It’s a complex piece of technology that forms the backbone of many electronic devices.

| V-2 | Burning stops within 30 seconds | Yes |
| V-1 | Burning stops within 30 seconds | Drips of particles allowed as long as they are not inflamed |
| 94V-0 | Burning stops within 10 seconds | Drips of particles allowed as long as they are not inflamed |
| 5VB | Burning stops within 60 seconds | No; plaque specimens may develop a hole |
| 5VA | Burning stops within 60 seconds | No; plaque specimens may not develop a hole |
While the 94v0 rating is a highly desirable standard for circuit boards, it’s not the only flammability standard out there. Other ratings under the UL 94 standard include HB, V-1, V-2, 5VA, and 5VB. Each of these ratings represents a different level of flammability, and understanding these differences can help you make more informed decisions when it comes to choosing materials for your electronic devices.
- HB (Horizontal Burn): Materials with an HB rating burn slowly and are less flame retardant than those with a V rating. These materials are tested in a horizontal position, and to pass, they must not burn at a rate greater than a specified speed or cease burning before reaching a marked point.
- V-1, V-2 (Vertical Burn): These materials are tested in a vertical position. V-1 and V-2 materials must stop burning within a certain time after the ignition source is removed, with V-1 materials being slightly more flame retardant than V-2. Both these materials may drip flaming particles while burning.
- 5VA, 5VB (Vertical Burn with Impact): These materials are subjected to both a flame test and an impact test. 5VA materials are more flame retardant than 5VB materials and do not allow flaming drips. Both these materials, however, may develop a hole due to burning.
The 94v0 rating is the most stringent of these standards. Materials with this rating stop burning within 10 seconds and do not drip flaming particles, providing a high level of fire safety. This makes 94v0 circuit boards an excellent choice for electronic devices, especially those that need to operate in harsh or high-temperature environments.
