What is the difference between 3240 epoxy board and FR4 tablo epoksidik?

1. Translucent color.

Koulè FR4 tablo epoksidik la trè natirèl, yon ti jan jade, ak koulè 3240 tablo epoksidik la yon ti jan kliyote. Li pa sanble trè natirèl. Pifò nan koulè yo pa trè inifòm.

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 ka natirèlman extend nan evènman an nan yon dife.

5. FR4 has good dimensional stability.

Estabilite dimansyon nan FR4 se pi bon pase sa ki nan 3240, ak pandan pwosesis la peze, tolerans epesè nan FR4 se tou pi bon pase sa yo ki an 3240, ki se pi plis apwopriye pou pwosesis.

6. Low water absorption.

Absòpsyon dlo li yo (D-24/23, epesè plak 1.6mm): ≤19mg, ki bay yon bon èd pou itilize li nan transformateur mouye ak lòt ekipman.
