What is the Shengyi LNB33 pcb material?
LNB33 laminate is founded upon a sophisticated glass-reinforced hydrocarbon and ceramic dielectric system. The laminate is characterized by a high glass transition temperature (Tg) exceeding 280°C. This property ensures exceptional dimensional stability and minimal warpage under elevated temperatures, which is an indispensable characteristic for maintaining circuit integrity during lead-free soldering processes and long-term operational conditions.
The dielectric constant (Dk) of LNB33 laminate is approximately 3.30±0.05 at 10 GHz (as per IPC-TM-650 2.5.5.5). This low and highly stable Dk is of paramount importance for precise impedance control and predictable signal velocity across a wide spectrum of frequencies.
The loss tangent of laminate is approximately 0.0025 at 10 GHz (in accordance with IPC-TM-650 2.5.5.5). This minimal loss tangent plays a crucial role in maximizing signal strength, minimizing heat generation in power amplifiers, and preserving the signal-to-noise ratio in sensitive receivers, especially in high-frequency applications.
Moreover, the laminate features a tightly regulated, low Z-axis coefficient of thermal expansion (CTE) and remarkable dimensional stability across temperature and humidity fluctuations. This effectively minimizes stress on plated through-holes, prevents warping in large antenna panels, and ensures consistent registration in multilayer structures, all of which are crucial for manufacturing processes.

The features of the Shengyi LNB33 PCB material
Glass Transition Temperature (Tg)
The laminate features a high Tg＞280°C, ensuring excellent dimensional stability and minimal warpage under elevated temperatures—an essential characteristic for maintaining circuit integrity during lead-free soldering and long-term operation.
Low Dielectric Constant (Dk)
With a low Dk of 3.30 +/- 0.05 @ 10 GHz (IPC-TM-650 2.5.5.5). This low and exceptionally stable Dk is crucial for precise impedance control and predictable signal velocity across wide frequency ranges.
Low Dissipation Factor (Df)
With a low Df of 0.0025 @ 10 GHz (IPC-TM-650 2.5.5.5). This minimal loss tangent is vital for maximizing signal strength, minimizing heat generation in power amplifiers, and preserving signal-to-noise ratio in sensitive receivers, especially critical for high-frequency operation.
Glass-Reinforced Hydrocarbon and Ceramic Dielectric System
This advanced composite material system provides excellent thermal conductivity, mechanical strength, and long-term reliability in harsh environments. This hybrid dielectric composition delivers a unique balance of electrical performance and mechanical strength, ideal for complex, high-frequency environments.
Stable Electrical Properties Across Frequency Ranges
The material maintains consistent Dk and Df values across a wide frequency range, reducing phase distortion and ensuring reliable RF performance. The laminate offers minimal variation in Dk and Df over a wide frequency range, ensuring consistent performance in broadband applications.
Low Z-Axis Coefficient of Thermal Expansion (CTE)
The laminate features a low Z-axis CTE, which significantly improves plated-through-hole (PTH) reliability, especially in multi-layer boards subjected to thermal cycling. These properties improve reliability in multilayer PCB assemblies and minimize warping or distortion during thermal cycling.
What are the applications of the Shengyi LNB33 PCB material?
The advanced electrical and thermal properties of LNB33 laminate make it highly suitable for a variety of high frequency and wireless communication systems:
LNA/LNB
Critical for satellite TV and communication systems, where minimal signal loss (low Df) and stable performance are essential for receiving weak signals. Ideal for reducing signal loss and ensuring clarity in satellite communications.
High-Frequency Wireless Communication Devices
Ideal for RF front-end modules, power amplifiers, and other key components in wireless infrastructure. From Wi-Fi 6/6E modules to millimeter-wave sensors, LNB33 laminate supports the growing demand for compact, high-performance wireless connectivity solutions.
Satellite Signal Transmission Equipment
Used in both ground-based receivers and satellite dishes, LNB33 laminate ensures stable RF performance in challenging outdoor environments. Used in ground station equipment, satellite transceivers, and onboard systems where reliability, thermal stability, and consistent electrical properties are non-negotiable.
Microstrip and Cellular Base Station Antennas
The stable Dk and low loss make LNB33 laminate excellent for designing precision microstrip filters, couplers, and transmission lines. This LNB33 laminate is a preferred substrate for fabricating microstrip patch antennas and cellular base station antenna arrays.
Base Station Antennas and Power Amplifiers
LNB33 laminate supports the fabrication of high-efficiency RF power amplifiers and broadband antennas used in modern cellular infrastructure, offering reliable performance at microwave frequencies.
Processing Advantages of the Shengyi LNB33 PCB material
Excellent Dimensional Stability
LNB33 laminate resists warping and movement during lamination, drilling, and assembly processes, ensuring layer-to-layer alignment in complex multilayer RF boards and maintaining the geometric accuracy vital for antenna radiation patterns.
Suitable for Use in Epoxy Glass Multilayer Board Hybrid Designs
LNB33 laminate can be easily integrated into hybrid multilayer PCBs, combining high-frequency performance with standard FR-4 or high-Tg epoxy glass layers—offering flexibility in design and fabrication. This drastically optimizes cost without sacrificing RF performance where it matters most.
Cost-Effective and Readily Available
LNB33 laminate offers a very competitive price-to-performance ratio. Shengyi’s global scale ensures reliable supply chains, making it a practical choice for volume production. Compared to more exotic high-frequency materials like PTFE or Rogers laminates, LNB33 laminate offers a cost-efficient alternative with comparable RF performance—making it ideal for medium to large-scale production runs.
Shengyi LNB33 laminates offer an ideal solution for engineers seeking high-frequency performance, thermal stability, and manufacturing efficiency. By choosing LNB33 laminate, manufacturers can achieve superior performance, enhanced safety, and extended product lifetimes.
