Product Description

Introduction: The Rise of Transparent Flexible Circuits

In the fast-evolving world of electronics, the demand for slimmer, more flexible, and visually appealing circuit materials is growing rapidly. Shengyi Technology’s SF490 PET Transparent Flexible Copper Clad Laminate (FCCL) is at the forefront of this innovation, offering a unique combination of high transparency, flexibility, and reliability—making it ideal for next-gen applications like flexible displays, touch panels, wearable tech, and smart electronics.

Whether it’s for transparent LED screens, foldable smartphones, or rollable displays, the SF490 FCCL provides the perfect balance of optical clarity, mechanical durability, and electrical performance, setting a new standard for modern electronics.

Why Choose SF490 PET Transparent FCCL?

1. High Transparency & Aesthetic Appeal

Optical-grade PET film with >90% light transmittance, enabling near-invisible circuit integration.
Flawless surface finish—no bubbles or impurities, ensuring a sleek, premium look for transparent displays and curved screens.

2. Unmatched Flexibility & Bend Resistance

Customizable thickness (75–188µm) paired with ultra-thin copper foil (½OZ–1OZ) for superior flexibility.
Dynamic bending capability (radius ≤1mm, 100,000+ bend cycles) without performance loss—perfect for foldable phones, rollable screens, and wearable devices.

3. Superior Electrical Performance

Low dielectric constant (Dk) & loss (Df), optimizing high-frequency signal transmission (ideal for 5G mmWave & flexible antennas).
Controlled copper roughness for consistent impedance and enhanced signal integrity.

4. Extreme Durability: Heat & Chemical Resistance

Wide operating range (-40°C to +130°C), compatible with lead-free soldering & SMT processes.
Resists acids, alkalis, and solvents, ensuring stability in harsh environments.

5. Eco-Friendly & Safe

Halogen-free & RoHS/REACH compliant, aligning with green manufacturing trends.
UL-certified & 94V-0 flame retardant, guaranteeing safety in consumer electronics.
