High Frequency PCB

If you’re looking to optimize your wireless networks or applications that rely on seamless signal transmission, investing in high frequency PCBs is a smart choice.

High Frequency PCB Manufacturing Services

Highleap Electronics specializes in manufacturing a wide range of high-frequency PCBs tailored to RF and microwave applications. Our capabilities include multi-layer high-frequency stack-ups, mixed dielectric lamination (hybrid build-ups), and complex impedance-controlled routing. We maintain a stable inventory of high-end HF materials such as Rogers RO4003C, RO4350B, RO3003, RT/duroid 5880, Taconic RF-35, TLX, Isola IS620, and more—ensuring shorter lead times and reliable sourcing. Whether you require antenna-integrated designs, 77GHz radar PCBs, or hybrid constructions, Highleap delivers precision and performance with every board.

Design Support & Cost Optimization for High-Frequency PCBs

Designing PCBs for RF, microwave, and mmWave applications requires more than standard layout practices. At Highleap Electronics, our engineering team works closely with customers to optimize signal integrity, impedance control, and manufacturability right from the design stage. We help you avoid common pitfalls like excessive vias, long signal loops, and improper trace routing—ensuring your layout supports clean signal transmission even at GHz frequencies.

To support reliable high-frequency performance, we follow proven layout guidelines: minimizing crosstalk between signal lines, using 45° trace bends instead of sharp corners, and reducing the use of lossy soldermask on critical signal paths. We also advise on material choices that reduce dielectric loss and surface roughness issues caused by skin effect at high frequencies. Whether it’s antenna design or radar circuitry, our insights help customers avoid EMI issues and achieve better signal-to-noise performance.

Highleap also provides cost-effective hybrid stack-up solutions, combining premium RF cores like Rogers or Taconic with FR-4 for non-critical layers. This balances performance with budget control. From stack-up planning to DFM checks and impedance matching support, we’re here to guide you through every step—accelerating your design cycle while reducing iteration costs.

Materials for High-Frequency PCB Fabrication

Material selection is at the core of high-frequency PCB performance. At Highleap Electronics, we maintain a well-managed inventory of high-frequency laminates to support fast prototyping and stable mass production. Our factory works closely with globally recognized suppliers to ensure material authenticity, consistent dielectric performance, and reliable sourcing.

Extensive In-House Inventory of HF Materials

We stock a wide range of high-performance RF and microwave materials, including:

    • Rogers: RO4003C, RO4350B, RO3003, RO3010, RT/duroid 5870, 5880, 6002, 6010LM
    • Taconic: RF-35, TLY-5, TLX-8, TSM-DS3, CER-10
    • Isola: IS620, I-Tera MT40, Astra MT77
    • Panasonic: Megtron 6, Megtron 7 (for hybrid RF + digital systems)
    • Nelco: N4000-13EPSI, N9000 series
    • Arlon: 85N, AD255C
    • Other specialty substrates: PTFE, LCP, PPO, and ceramic-filled materials for millimeter-wave and radar-grade applications

These materials cover a broad range of dielectric constants (Dk), dissipation factors (Df), and thermal coefficients, allowing us to tailor the performance of your design across 1GHz to 77GHz+ frequencies.

Support for Hybrid Stack-Ups and Mixed Lamination

We offer full support for hybrid PCB construction, combining high-frequency materials with standard FR4 or low-loss core/prepreg systems to balance performance, cost, and manufacturability. Our experienced CAM and process engineers can optimize your layer stack-up to ensure:

    • Stable impedance control across transmission lines
    • Low insertion loss at high frequencies
    • Minimal dielectric skew in differential pairs
    • Compatibility with specific copper weights and surface finishes

Flexible Material Procurement and Customer-Supplied Materials

In addition to our long-term stocked materials, we also support:

    • Rapid procurement of customer-specified laminates (including rare or custom-coded materials) via trusted distributors
    • Customer-supplied material processing (consignment) with full handling compliance
    • Material substitution suggestions based on electrical, mechanical, and thermal equivalence for cost or lead time optimization

Our sourcing team works closely with Rogers, Taconic, and regional agents to ensure fast material lead times and secure original manufacturer supply channels, especially for PTFE-based and high-Dk materials with long procurement cycles.
