1. Product Positioning: The "Performance Cornerstone" for High-Frequency Signal Transmission
This product is a PTFE-based copper-clad laminate (CCL) specifically designed for high-frequency and high-speed scenarios such as 5G communications, millimeter-wave radar, satellite communications, and high-end servers. With "super loss material" as its core technical support, it addresses three key pain points in high-frequency signal transmission—"high attenuation, strong interference, and thermal runaway"—through exceptional dielectric properties and stable physical characteristics. It provides a low-loss, high-stability, and long-life signal transmission carrier for high-end electronic devices, serving as a critical foundational material for breakthroughs in next-generation information and communication technologies.
2. Core Technical Advantages: Super Loss Material Drives High-Frequency Performance Leap
(1) Millisecond-Level Response + Low Attenuation: "Zero Barrier" for High-Frequency Signal Transmission
Leveraging the unique molecular structure of super loss material, the product delivers outstanding signal transmission performance:
On one hand, its power throughput response speed for high-frequency signals reaches the millisecond level, enabling quick adaptation to dynamic power change scenarios (e.g., radar signal transmission/reception, 5G base station signal switching);
On the other hand, it effectively reduces energy loss during signal transmission, with signal attenuation rate 30% lower than that of traditional CCLs. Even in the millimeter-wave band above 60GHz, it maintains signal integrity, avoiding communication delays and data errors caused by attenuation, and meeting the core "high data rate, low latency" requirements of high-end communication devices.
(2) Exceptional Dielectric Properties: Stability Guarantee Under All Operating Conditions
Through precise material formulation and advanced molding processes, the product achieves "low loss and high stability" in dielectric performance:
Dielectric Loss (DF) as low as 0.0007: Far lower than conventional high-speed CCLs in the industry (DF ≈ 0.002-0.004), it significantly reduces dielectric loss in high-frequency signal transmission. Especially in long-term high-frequency operating scenarios, it effectively lowers device heat generation and extends the service life of components;
Dielectric Constant (DK) stable at 3±0.04: The DK value not only falls within the ideal range (3-4) for high-frequency communications but also has an extremely small fluctuation range (±0.04). Even under complex operating conditions with temperature and humidity changes, it maintains stable dielectric constant, preventing signal phase shift and ensuring communication accuracy;
Low Coefficient of Thermal Expansion (CTE): 18.26-20.23 PPM/℃: Highly matched with the CTE of copper foil, it effectively avoids delamination and cracking of the CCL caused by thermal expansion and contraction during high-low temperature cycles (-55℃~125℃), ensuring structural stability of devices in extreme environments (e.g., aerospace, outdoor base station scenarios).
(3) Efficient Thermal Management: A "Safety Barrier" Under Extreme Conditions
To address the "heat accumulation" issue of high-frequency devices during long-term operation, the product achieves efficient thermal management through dual thermal performance design:
TCDK value of only +6.4: The Temperature Coefficient of Dielectric Constant (TCDK) is extremely low, meaning temperature changes have minimal impact on dielectric performance. Even when the local temperature of the device rises above 85℃, it still maintains stable signal transmission performance;
Outstanding Resistance to Extreme Temperature and Humidity: With a Thermal Decomposition Temperature (TD) of up to 534℃—far exceeding that of traditional CCLs (TD ≈ 300-400℃)—it can withstand extreme high-temperature environments. Meanwhile, it exhibits excellent high-humidity resistance: after being placed in an environment with 95% relative humidity at 40℃ for 1000 hours, its dielectric performance and mechanical strength show no significant attenuation, making it suitable for industrial control and marine communication scenarios with high temperature and humidity.
3. Environmental Protection Characteristics: Green Processes Align with Sustainable Development
(1) Halogen-Free and Environmentally Friendly, Leading in Compliance
The product adopts green and environmentally friendly production processes, free of harmful substances such as halogens (chlorine, bromine, etc.) and heavy metals. It fully complies with EU RoHS 2.0 (Restriction of Hazardous Substances Directive) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) standards, eliminating environmental and human health hazards during production, use, and disposal, and meeting the environmental access requirements of high-end electronic manufacturing enterprises worldwide.
(2) Sustainable Design, Reducing Total Lifecycle Cost
The PTFE material offers excellent chemical stability and aging resistance, extending the product's service life by more than 50% compared to traditional CCLs and reducing equipment replacement frequency. Additionally, waste products can be recycled through professional recycling processes to minimize resource waste, aligning with the sustainable development trend of the electronics industry under the "dual carbon" goal.
