We are excited to introduce our newly shipped SF305 Halogen-Free Flame-Resistant Flexible PCB, a high-performance solution designed for advanced flexible electronic applications. Developed using Shengyi Technology’s SF305 adhesive double-sided flexible copper-clad laminate (FCCL), this PCB is engineered to meet the demanding requirements of high-frequency signal transmission and dynamic bending scenarios. Ideal for industries such as foldable mobile phones, wearable devices, automotive electronics, and medical devices, this PCB combines cutting-edge technology with exceptional reliability and performance.
Why Choose the SF305 Flexible PCB?
1. Unmatched High-Frequency Performance:
With a dielectric constant (Dk) of 3.3 and a dissipation factor (Df) of 0.0019 at 10GHz, this PCB ensures minimal signal loss, making it perfect for high-frequency and millimeter-wave applications.
2. Exceptional Flexibility and Durability:
Designed to withstand repeated bending, the SF305 PCB boasts a peel strength of ≥1N/mm and outperforms industry standards in dynamic bending tests. It’s the ideal choice for foldable and wearable devices that demand long-term reliability.
3. Built to Survive Harsh Conditions:
Rigorously tested for high-temperature and high-humidity environments (double 85) and thermal shock resistance (-40°C to 125°C), this PCB is engineered to thrive in the most demanding settings. Its moisture absorption rate of ≤1.5% and chemical resistance of ≥80% further enhance its durability.
4. Eco-Friendly and Safe:
Compliant with UL94 V-0 flammability standards, the SF305 PCB is halogen-free, making it an environmentally friendly choice for modern electronics.
5. Cost-Effective
Offering a superior cost-performance ratio compared to imported alternatives like DuPont Pyralux AP.
