Transparent PET Fleixble FPC PCB 1-layer 4mil Immersion Silver and Carbon traces
Introduction
In the rapidly evolving world of electronics, the demand for innovative, high-performance materials is at an all-time high. Shengyi Technology’s Transparent PET Flexible PCB (SF490) is a groundbreaking solution designed to meet the needs of modern electronic applications. This advanced halogen-free PET film-based transparent FCCL (Flexible Copper Clad Laminate) combines high transparency, exceptional flexibility, and reliable electrical performance, making it an ideal choice for cutting-edge technologies such as flexible displays, touch panels, wearable devices, and smart electronics.
With its optical-grade PET film and ultra-thin copper foil, the Transparent flexible PCB offers a nearly invisible circuit design, making it perfect for applications where aesthetics and functionality are equally important. Whether you’re developing transparent displays, curved screens, or foldable devices, this 1-layer flexible PCB delivers unmatched performance and reliability.
Core Advantages
1. High Transparency and Aesthetics
The PET PCB features an optical-grade PET film with a light transmittance of over 90%, enabling a nearly invisible circuit design. This makes it ideal for high-end applications such as transparent LED displays, smart windows, and curved screens. The material’s high surface flatness ensures a flawless finish, free from bubbles or impurities, enhancing the visual appeal of end products.
2. Excellent Flexibility and Bend Resistance
Designed for dynamic applications, the SF490 offers exceptional flexibility and bend resistance. With a customizable base material thickness (typically 75 - 188 µm) and ultra-thin copper foil (1/2OZ - 1OZ), it supports a bending radius of ≈1mm and can withstand over 100,000 bending cycles. This makes it perfect for foldable smartphones, rollable screens, and other cutting-edge devices requiring long-term durability.
3. Stable Electrical Performance
The SF490 ensures reliable signal transmission with its low dielectric constant (Dk) and low dielectric loss (Df), making it suitable for high-frequency and high-speed applications such as 5G millimeter waves and flexible antennas. The controllable surface roughness of the copper foil further enhances signal integrity, ensuring consistent performance.
4. High Temperature Resistance and Chemical Resistance
This High transparency flexible PCB operates reliably across a wide temperature range (-40°C to +130°C) and is compatible with lead-free soldering processes, meeting the requirements of SMT manufacturing. Its resistance to acids, alkalis, and solvents ensures structural stability and electrical reliability even in harsh environments.
5. Environmental Friendliness and Reliability
The SF490 complies with international environmental standards such as RoHS and REACH, featuring a halogen-free design that aligns with the trend of green manufacturing. It has also passed UL certification and boasts excellent flame retardancy (94V-0 grade), ensuring the safety and reliability of end products.
