High-Speed & Low-Loss PCB Laminate for RF, HPC, and Telecom
At Highleap Electronics, we specialize in manufacturing and assembling PCBs using advanced low-loss materials like TU-883, the core of the ThunderClad® 2 laminate system. Designed by Taiwan Union Technology Corporation (TUC), TU-883 is a high-performance resin system reinforced with E-glass fabric—perfect for applications that demand low Df, stable dielectric constant, and exceptional thermal and mechanical reliability.
Key applications include:
- High-speed backplanes and line cards
- RF and microwave front-end circuits
- 5G base stations and network infrastructure
- Servers, storage, routers, and telecom systems
TU-883 is halogen-free, RoHS compliant, and compatible with modified FR-4 processes. It provides reliable performance across soldering cycles, thermal stress, and environmental extremes.

Why TU-883 Is Ideal for High-Speed, Multilayer PCB Fabrication
TU-883 is a high-performance laminate designed to meet the stringent demands of today’s high-speed, high-frequency digital and RF circuits.
Whether you’re designing a 28G+ SerDes backplane or a multilayer RF board, TU-883 delivers exceptional signal integrity, dimensional stability, and thermal reliability, making it a popular Rogers alternative for engineers looking to optimize both performance and cost.
Key Advantages of TU-883 in High-Speed Designs:
- Low loss material for GHz-speed signals — with a dissipation factor (Df) of just 0.0045 at 10 GHz, TU-883 reduces signal attenuation in long traces or multilayer interconnects.
- Stable dielectric constant (Dk = 3.39) for predictable impedance control and simulation accuracy.
- Excellent Z-axis CTE (2.5%) ensures consistent plated-through-hole (PTH) reliability across complex multilayer stackups.
- Ideal for high-frequency multilayer PCB stackup with hybrid integration (FR4, polyimide, or other TUC materials).
- Halogen-free & RoHS compliant, ideal for green electronics and export markets.
- CAF-resistant and highly processable, making it suitable for HDI, BGA, and fine-line applications.
If you’re looking for low-loss PCB laminates for backplane routers, 5G base stations, or high-frequency test equipment, TU-883 is a trusted choice among RF and digital hardware designers worldwide.
