FR-4 green/yellow/black board is made of imported non-alkali glass fiber cloth impregnated with imported epoxy resin and flame retardant, adhesive, etc. Which by processing under pressure and heat,It’s rigid insulating laminated sheet.
The product has the following characteristics:
1. Rich variety and high accuracy tolerance
2. Excellent flame retardant (UL 94 V-0 Grade)
3. Excellent voltage resistance (electrical strength≥16Kv/mm)
4. Excellent resistance water absorbency (water absorption rate≤0.2%)
5. Excellent heat resistance (Class F)
6. Excellent thermal impact (operating temperature -273 ℃ to +155 ℃)
7. Excellent mechanical strength & Automatic Machining
8, RoHS, Reach certified products
