What is the difference between 3240 epoxy board and FR4 epoksidna ploča?

1. Translucent color.

Boja epoksidne ploče FR4 je vrlo prirodna, pomalo žadna, a boja 3240 epoksidne ploče pomalo trepće. Ne izgleda baš prirodno. Većina boja nije ujednačena.

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 se može prirodno ugasiti u slučaju požara.

5. FR4 has good dimensional stability.

Dimenzionalna stabilnost FR4 bolja je od one kod 3240, a tijekom procesa prešanja tolerancija debljine FR4 također je mnogo bolja od one kod 3240, koja je prikladnija za obradu.

6. Low water absorption.

Njegova apsorpcija vode (D-24/23, debljina ploče 1.6 mm): ≤19 mg, što mu dobro pomaže u uporabi u mokrim transformatorima i drugoj opremi.
