94v0: Printed circuit board with high fire rating

The circuit board in the electronic device is a core component. The equipment we use will face different external environments, such as high temperature, high pressure, low temperature, humidité, etc., so the materials of the circuit board must be safe. Donc, we need to classify the underlying materials to determine which electronic circuit board is safe for your project. The 94V0 circuit board is a good choice. Let’s figure it out together.

What is 94V0?

94V-0 is refractory:
The UL94 combustible level is the most commonly used plastic material standard for many businesses. It is generally used to evaluate the ability to extinguish speed after being ignited. A variety of judgment methods can be obtained according to the burning speed, burning time, anti-dripping ability, and dripping beads. Each tested material can obtain many values according to color or thickness. When the material of a product is selected, its UL level should meet the thickness requirements of the wall portion of the plastic parts. UL level should be reported with thickness value, and it is not enough to report UL level without thickness.

Plastic flame retardant levels are increased by HB, V-2, V-1 to V-0 step by step:

HB: The bottom flame retardant level in UL94. For samples of 3 à 13 mm thick, the combustion speed is less than 40 mm per minute; for samples of less than 3 mm thick, the combustion speed is less than 70 mm per minute;

V-2: After two 10-second combustion tests of the sample, the flame was extinguished within 60 seconds. It can be burning.

V-1: After two 10-second combustion tests of the sample, the flame was extinguished within 60 seconds. There must be no burning.

V-0: After two 20-second combustion tests of the sample, the flame was extinguished within 30 seconds. There must be no burning.

What are the advantages of 94V0 PCB?

94V0 PCB has a unique advantage. It can adapt to various harsh natural environments. High temperatures are a problem for many electronic devices. The main function of 94V0 PCB is fire prevention. Compared to other PCB types, the 94V0 circuit board is more durable and longer.
Another overwhelming feature of the use of V-0 PCBs in military, aerospace and other heavy equipment is that the UL 94V-0 PCB has very ideal temperature control or modulation panel characteristics. This function helps control the temperature of the device by regulating the equipment and preventing problems caused by overheating. Materials used to make 94V0 circuit boards have a high level in the UL 94V-0 combustible test, so it is flame retardant.
The 94V0 circuit board is designed with a standardized design. It has standard connector pins to make it easier to install and weld electronic components. Le Conception de PCB improvement includes a multi-layer circuit board structure covering the conductive copper lining and insulating material. Par conséquent, a large circuit on the compact board.

94V-0 PCB features
1. The materials used in the 94V-0 printed circuit board are the highest rated materials in the UL 94 flammable test classification. Donc, they are almost flammable and show strong resistance to strong thermal stress and heat damage.
2. 94V-0 rated circuit board can minimize PCB surface area by enabling large stack/layered options. Due to the huge heat and heat dissipation limit of the circuit board, this choice is usually avoided.
3. The 94V-0 circuit board has standard connector pins, which make it easy to install and assemble various electronic components.
4. Another important feature of the 94V-0 class circuit board is that it helps maintain signal integrity.

Application of 94V-0 circuit board

The cost of a 94V-0 circuit board is high. So you are unlikely to see them in consumer electronics. Cependant, they are widely used in more sensitive industries. In these industries, a small error can lead to major confusion. Although the cost is still high, some manufacturers use V-class printed circuit boards in consumer electronics to produce high-quality equipment. The application of these circuit boards in the following areas and industries.

94V-0 printed circuit boards are more common in the medical industry. Due to the industry’s requirements for accuracy, the UL 94V-0 circuit board is an ideal choice. Because they have the ability to withstand harsh environmental conditions, the medical industry is likely to appear in the form of high radiation and heating environments.

94V-0 PCB is also very popular in military-grade equipment, because the application field also needs perfect and excellent performance. Military-grade equipment is usually used in harsh environments for intensive operations, and works at high voltage and high power. Donc, the UL 94V-0 printed circuit board will be a perfect choice for military-grade equipment.
The security industry is another field of UL 94V-0 circuit boards. They have a wide range of applications for secure cameras and digital sticks. Because the low flammability of these circuit boards helps to maintain the functions of these equipment when fire occurs.
