Polyimide 25um FPC Flexible PCB 2-layer 0.24mm Thick Immersion Gold
In the era of flexible and wearable electronics, the demand for high-performance, reliable, and lightweight printed circuit boards (PCBs) has never been greater. The Polyimide 25µm FPC PCB, built using Shengyi Technology’s SF305 Halogen-Free Flame-Resistant PI Film-Based FCCL, is a cutting-edge solution designed for high-frequency signal transmission and dynamic bending applications. This flexible PCB is engineered to meet the stringent requirements of modern electronics, including foldable mobile phones, wearable devices, automotive electronics, and medical devices. With its exceptional electrical, thermal, and mechanical properties, the Polyimide 25µm FPC PCB is the ideal choice for industries pushing the boundaries of innovation.
Key Features of Polyimide 25µm FPC PCB
1.Low Dielectric Loss and Stable Dielectric Constant:
The SF305 laminate FPC flexible printed circuit boasts a dielectric constant (Dk) of 3.3 at 10GHz (measured by IEC-61189-2-721), ensuring consistent signal integrity in high-frequency applications. Its dissipation factor (Df) is an ultra-low 0.0019 at 10GHz, minimizing signal loss and enabling high-speed data transmission with minimal distortion.
2.Excellent Flexibility and Durability:
With a peel strength of≥1N/mm and moisture absorption of≤1.5%, the Polyimide 25µm FPC PCB offers superior flexibility and durability, making it ideal for dynamic bending scenarios.
3.High Thermal and Chemical Resistance:
The polyimide flexible circuit PCB features a dielectric strength of 134 V/µm and chemical resistance of≥80%, ensuring reliable performance in harsh environments. It also meets the UL94 V-0 flammability standard, making it safe for high-risk applications.
4.Halogen-Free and Environmentally Friendly:
The SF305 laminate flexible circuit board is halogen-free and complies with global environmental standards, making it a sustainable choice for green manufacturing.
5.Cost Optimization:
Compared to similar imported products (e.g., DuPont Pyralux AP), the SF305 laminate offers a higher cost-performance ratio and faster supply chain response.
Why Choose Polyimide 25µm FPC PCB?
1.High Frequency and Flexibility
The Polyimide 25µm polyimide flex PCB breaks through the high-frequency performance bottleneck of traditional FPCs, supporting millimeter-wave and high-speed data transmission.
2.Extraordinary Long Lifespan
With superior dynamic bending performance, this PCB ensures the reliability of folding devices, making it ideal for foldable smartphones and wearable electronics.
3.LResistant to Harsh Environments
The PCB has passed rigorous reliability tests, including high-temperature and high-humidity (double 85) and thermal shock (-40°C to 125°C), ensuring performance in extreme conditions.
4.Cost-Effective Manufacturing
The SF305 laminate High-Frequency FPC is compatible with traditional FPC processing technology, reducing production costs without compromising performance.
