We're happy to introduce a flexible PCB based on Shengyi Technology’s SF490 PET Transparent Flexible material which designed to meet the growing demands of modern electronics. Combining high transparency, exceptional flexibility, and reliable performance, this 1-layer flexible PCB is crafted using Halogen-Free PET Film-Based Transparent FCCL (SF490). It is an ideal choice for applications such as flexible displays, touch panels, wearable devices, and smart electronics, offering a perfect blend of aesthetics and functionality.
Unmatched Transparency for Cutting-Edge Designs
This transperant flexible PCB features optical-grade PET film with over 90% light transmittance, enabling nearly invisible circuit designs. This makes it perfect for high-end applications like transparent displays and curved screens, where both functionality and aesthetics are critical. The material’s high surface flatness ensures a flawless, bubble-free finish, giving end products a sleek and professional appearance.
Exceptional Flexibility for Dynamic Applications
Designed to withstand rigorous use, this flexible PCB offers outstanding flexibility and bend resistance. With customizable base material thickness (75 - 188μm) and ultra-thin copper foil (1/2OZ - 1OZ), it supports dynamic bending with a bending radius of ≤1mm and over 100,000 bend cycles. This makes it an excellent choice for foldable devices, rollable screens, and other innovative flexible electronics.
Reliable Electrical Performance for High-Frequency Applications
This PCB delivers stable electrical performance, thanks to its low dielectric constant (Dk) and dielectric loss (Df). These properties minimize signal transmission loss, making it suitable for high-frequency and high-speed signal transmission, including 5G millimeter waves and flexible antennas. Additionally, the controlled surface roughness of the copper foil ensures consistent line impedance and superior signal integrity.
Durability in Challenging Environments
Built to perform in harsh conditions, this flexible PCB operates reliably across a wide temperature range (-40°C to +130°C). It is resistant to acids, alkalis, and solvents, ensuring long-term durability even in complex environments. The PCB is also compatible with lead-free soldering and SMT manufacturing processes, making it a versatile choice for various industrial applications.
Eco-Friendly and Safety
This PCB complies with international environmental standards such as RoHS and REACH, reflecting its commitment to sustainability. Its halogen-free design aligns with the trend of green manufacturing, while its UL certification and excellent flame retardancy (94V-0 grade) ensure the safety and reliability of end products.
