The circuit board 3240 epoxy board and FR4 board are two kinds of epoxy boards commonly used in the market at present. Everyone says FR4 is better than 3240. What's the difference between them?
Difference 1: FR4 has good flame retardant performance.
FR4 is a modified 3240 epoxy plate.FR4 epoxy plate flame retardant performance in accordance with the national ul94v-0 standard.3240 epoxy plate has no flame retardant property.
Difference 2: colour and lustre is bright.
The color of FR4 is very natural, a little jade, while the color of 3240 epoxy board is a little blink.It doesn't look natural.Most colors are not even.
Difference three: no radiation FR4, environmental protection.
Epoxy board is containing halogen, which is not very environmentally friendly to the environment and human body.Also does not accord with the national green sustainable development strategy.The FR4 epoxy plate is the opposite.
Difference 4: FR4 has good dimensional stability.
The dimensional stability of FR4 is better than that of 3240, and the thickness tolerance control of FR4 is much better than that of 3240 in the pressing process, so it is more suitable for processing.
Difference 5: FR4 can turn off the fire.
FR4 can have the function of natural extinguishing in case of fire.
Difference six: water absorption is small.
Water absorption (d-24/23, plate thickness 1.6mm) : ≤19mg, which is good for use in wet transformers and other equipment.
Because of its excellent performance, fr-4 epoxy board is now used as a material for insulating parts in the electrical and electronic industries.Of course, 3240 epoxy board because of its price advantage there is still a certain market.
