What is the difference between 3240 epoxy board and FR4 epoksie bord?

1. Translucent color.

Die kleur van die FR4 -epoksiebord is baie natuurlik, ‘n bietjie jade, en die kleur van die 3240 -epoksiebord flikker effens. Dit lyk nie baie natuurlik nie. Die meeste kleure is nie baie eenvormig nie.

2. FR4 has good flame retardant performance.

FR4 is an improved product of 3240 epoxy resin board. The flame retardant performance of FR4 epoxy board meets the national UL94V-0 standard. 3240 epoxy resin board has no flame retardant properties.

3. FR4 is non-radiation and environmentally friendly.

3240 epoxy resin board is halogen-containing, which is not very environmentally friendly to the environment and the human body. It also does not conform to the country’s green sustainable development strategy. The FR4 epoxy board is just the opposite.

4. FR4 can self-extinguish from the fire.

FR4 kan natuurlik geblus word in geval van ‘n brand.

5. FR4 has good dimensional stability.

Die dimensionele stabiliteit van FR4 is beter as dié van 3240, en tydens die persproses is die dikttoleransie van FR4 ook baie beter as dié van 3240, wat meer geskik is vir verwerking.

6. Low water absorption.

Die wateropname (D-24/23, plaatdikte 1.6mm): ≤19mg, wat ‘n goeie hulp bied vir die gebruik daarvan in nat transformators en ander toerusting.
