As 5G, automotive electronics, and data centers drive demand for faster signal transmission, high-frequency high-speed materials have become the backbone of advanced FPC (Flexible Printed Circuit), PCB (Printed Circuit Board), and rigid-flex PCB manufacturing. Shenzhen Huaruixin Electronics Co., Ltd. is a global ODM/OEM manufacturer specializing in FPC, PCB, and rigid-flex PCBs, certified to GB/T19001-2016/ISO 9001:2015 quality management system, with IAF international accreditation and CNAS national recognition. Leveraging years of technical accumulation, we offer professional insights into this critical material category.

1. Core Traits of High-Frequency High-Speed Materials for FPC/PCB/Rigid-Flex PCBs

High-frequency high-speed materials stand out for their performance advantages tailored to high-speed signal scenarios:

Low Dk & Df: Low dielectric constant (Dk) and dielectric loss (Df) minimize signal attenuation and crosstalk, ensuring signal integrity at frequencies above 1 GHz.

Stable Signal Transmission: Excellent impedance control (50Ω/100Ω typical) supports consistent signal propagation without distortion in high-frequency environments.

Thermal & Mechanical Reliability: Resists high temperatures (Tg ≥ 150°C) and maintains flexibility (for FPC) or rigidity (for PCB) under extreme operating conditions, compatible with reflow soldering.

Compatibility with Manufacturing Processes: Adapts to laser drilling, plasma treatment, and lamination processes, aligning with mass production requirements of FPC/PCB/rigid-flex PCBs.

2. Specific Application Fields

These materials are indispensable in high-performance electronic systems, with targeted applications across three core product lines:

2.1 FPC Applications

5G smartphones, tablets, and wearable devices (e.g., antenna flexes, high-speed data links).

Medical devices (e.g., minimally invasive surgical tools with high-frequency sensors).

Consumer electronics (e.g., foldable screen hinges, camera modules).

2.2 PCB Applications

Data center servers and switches (high-speed backplanes, optical module PCBs).

5G base stations and communication infrastructure (RF front-end PCBs).

Industrial control systems (high-precision measurement equipment PCBs).

2.3 Rigid-Flex PCB Applications

Automotive electronics (ADAS sensors, infotainment systems, EV battery management).

Aerospace and defense (avionics control units, satellite communication modules).

Industrial IoT devices (high-reliability connectivity in harsh environments).

3. Critical Considerations in Design, Production & Quality Inspection

Shenzhen Huaruixin Electronics emphasizes strict process control to address material-specific challenges, with key precautions:

3.1 Design Phase

Prioritize impedance matching by simulating trace width, spacing, and dielectric thickness to avoid signal reflection.

Optimize routing: Minimize trace length, avoid right-angle bends, and separate high-frequency traces from power/ground lines.

Select compatible substrates: Match material Dk/Df with operating frequency (e.g., PTFE-based materials for ≥24 GHz applications).

3.2 Production Phase

Control lamination parameters: Maintain consistent temperature (±2°C) and pressure to prevent delamination or uneven dielectric thickness.

Precision drilling: Use laser drilling for microvias (≤100μm) to ensure connectivity without damaging the low-loss substrate.

Cleanliness management: Avoid contamination during material cutting and processing, as impurities degrade dielectric performance.

3.3 Quality Inspection Phase

Test dielectric properties: Verify Dk/Df values via vector network analyzer (VNA) at target frequencies.

Check signal integrity: Measure insertion loss and return loss to ensure compliance with IPC standards.

Conduct reliability tests: Thermal cycling (-40°C to 125°C) and bending tests (for FPC) to validate long-term performance.
