FR4 Materials for PCB Manufacturing: Types and Properties
Explore the full range of FR4 PCB materials supported by Highleap Electronics, including standard, high-Tg, halogen-free, and high-CTI laminates from Shengyi, Kingboard, ITEQ, TUC, and Nanya.
PCB Manufacturing and Assembly Services with FR4 Materials
At Highleap Electronics, we manufacture PCBs using a full range of base materials—including FR4, high-frequency laminates, aluminum, polyimide, and other specialty substrates. This page focuses on the FR4 materials we support, which remain the most widely used choice for rigid PCB applications due to their balance of performance, reliability, and cost.
We stock and process FR4 laminates from leading brands such as Shengyi, Kingboard, ITEQ, TUC, and Nanya, including standard, high-Tg, halogen-free, and high-CTI options to meet diverse electrical and thermal performance needs.
FR4 Laminate Categories We Support
We support a comprehensive range of FR4 laminate types to meet various performance, environmental, and regulatory requirements:
Standard FR4
The most commonly used laminate, offering a balance of mechanical strength, thermal stability, and cost-efficiency. Suitable for general-purpose PCBs in consumer electronics, industrial control boards, and low-complexity applications.
High Tg FR4
With a glass transition temperature (Tg) of 150°C or higher, this material provides enhanced thermal resistance and dimensional stability—ideal for multilayer PCBs, power electronics, and lead-free soldering processes.
Halogen-Free FR4
An environmentally friendly choice that meets RoHS and REACH compliance, halogen-free laminates release less toxic gas under high temperature. Widely used in automotive electronics, medical devices, and products for export to regulated markets.
High CTI FR4
Designed with a Comparative Tracking Index (CTI) of 600V or higher, this type offers superior insulation performance. Commonly used in high-voltage power modules, LED lighting drivers, and white goods control boards.
Low Dk/Df FR4
These laminates provide stable dielectric constants and low dissipation factors, enabling better signal integrity at high frequencies. Perfect for applications requiring impedance control, such as communication systems and RF/microwave PCBs.
All types are available in various thicknesses, copper weights, and prepreg configurations. We support standard and customized stackups for 2 to 20+ layer rigid PCBs.
We also welcome customer-specified FR4 laminates and support production using customer-supplied materials. Our engineering team is available to evaluate laminate compatibility and recommend equivalent alternatives when needed.
