The main types of FR4 Glass Epoxy Sheet Insulation we currently produce:
Conventional Tg (130 degree ): suitable for ordinary consumer electronics.
Medium Tg (150 degree ): industrial equipment, automotive electronics.
High Tg (180 degree ): aerospace, high-frequency PCB.
1. Various colors: Compared with 3240 yellow, FR-4 is available in white, yellow, aqua, and black colors. And the surface is flat and smooth without bubbles, and the appearance is beautiful.
2. Fire protection level: UL94V0, the highest level of fire protection. Different from the general fire protection level, UL94V0 has achieved fire retardant effect. It can self-extinguish in a short time after the material passes through the burning state, ensuring the safety of life and property.
3. Strong insulation: FR-4 has extremely strong natural insulation performance. In dry and wet conditions, its electrical performance is still very good, making it a good choice for high-end electrical insulation parts.
4. High quality and practical: FR-4 still has good adaptability in different environments. Whether it is minus 100 degree or high temperature 180 degree , it can be applied.
5. Wide application: Because of its high-quality performance and strong plasticity, FR-4 is widely used in electronic and electrical insulation parts, as well as aircraft, high-speed trains, transformer insulation boards, precision planetary wheels, etc.
A: Usually the deposit ratio is 50% of the total amount of the order.
