FR4 94V0 double layer PCB
$14.80
Electronic devices generate a lot of heat when running for a long time. To ensure the stable operation of the equipment, the PCBs need to be made of reliable materials. This FR4 94V0 double layer PCB uses FR4 material, which has excellent flame-retardant properties and mechanical strength. FR-4 is a flame-retardant material, which means that the resin can self-extinguish after burning to prevent the spread of fire. It can effectively minimize the loss and casualties of property and personnel.

Questions & Answers
1.What is the meaning of 94V0?
94V-0 is a rating for PCB substrate materials, indicating the ability to resist catching fire and to self-extinguish if a fire occurs. Below are more details:
94: UL 94 standard.
V: Vertical, the test is carried out with the material in a vertical position.
0: This is the highest rating for the material under this standard. The materials will not burn within 10 seconds after the ignition source is removed.
2.What are the main flame ratings in the UL94V standard?
The main flame ratings are UL 94 V-0, UL 94 V-1, UL 94 V-2, UL 94 5VA and UL 94 5VB.
3.What are the different types of FR-4 materials?
Due to their properties, FR-4 materials come in various types, including Standard FR-4, High Tg FR-4, FR4 High IRC, FR4 with no copper, and Halogen-free FR-4.
4.What is the glass transition (TG) of FR4 materials?
Normal Tg of FR-4 ranges from 130ºC to 140ºC, medium Tg from 150ºC to 160ºC, and high Tg exceeds 170ºC.
5.Why choose FR4 for PCB materials?
FR4 is affordable and very suitable for prototyping or small-batch production. However, it is not ideal for high-frequency PCBs or flexible PCBs.
