As next-generation applications such as 5G modules, satellite communications, radar systems, and 112G SerDes links demand increasing signal speeds, dielectric loss becomes one of the biggest challenges in PCB design. A well-engineered low-loss PCB makes the difference between consistent transmission and signal degradation.
Highleap PCB Factory specializes in the production and assembly of low-loss PCBs designed for precision RF behavior, controlled impedance, and GHz-grade signal integrity. We handle advanced material systems and process complexity that many other vendors can’t accommodate.
What Makes a Low-Loss PCB?
Low-loss PCBs are manufactured using substrates with a lower dissipation factor (Df) and stable dielectric constant (Dk). These factors determine how much signal energy is absorbed into the material and how much propagates down the trace with minimal distortion.
Our facility fabricates PCBs using materials such as:
- Rogers RO4350B and RO3003 for RF front-end systems
- Megtron 6 and Megtron 7 for high-speed telecom backplanes
- Isola I-Tera MT40, TUC TU-872 SLK, and Panasonic Megtron 4
- Hybrid structures combining low-loss cores and conventional FR4
These materials are selected based on bandwidth, loss budget, insertion loss target, and z-axis stability. For ultra-high frequency applications such as mmWave and phased-array antennas, High-Frequency PCB materials like Teflon and Rogers enable minimal Df values, which is why they are often specified. Depending on the stackup, our HDI PCB options can also be combined with low-loss cores to meet space constraints in dense layouts.
Applications of Low-Loss PCBs
Devices that benefit from low-loss PCB designs include high-performance telecom routers, radar platforms, and optical data channels. Our factory has experience building High-Speed PCB configurations with tight return loss margins and skew control. Devices that benefit from low-loss PCB designs include:
- 5G mmWave modules and antenna arrays
- 24GHz and 77GHz automotive radar
- High-speed backplanes with PAM4 signaling
- Low-jitter clock distribution circuits
- Satellite RF communications boards
In these cases, reducing dielectric absorption is critical. Highleap PCB Factory provides simulation-based stackups, controlled lamination cycles, and panel-level validation to ensure that low-loss performance is not compromised.
Our Advanced Material PCB Capabilities
While standard FR4 PCB boards suffice for many applications, they fall short in GHz-class signal transmission. We work beyond standard FR4—our strength lies in handling difficult materials and demanding process requirements:
- Multi-material hybrid boards with Rogers + FR4
- High-layer count PCBs (up to 60+ layers) with blind and buried vias
- PTFE-based designs with plasma treatment for adhesion
- Precise press control for skew and z-axis impedance consistency
- Integration of thermal and RF design in one board
