Engineered Strategic Advantages

High-Frequency Signal Integrity

Engineered with premium low-loss FR4 substrates, these multilayer PCBs significantly minimize signal attenuation and impedance mismatches (reflection). They strictly adhere to the rigorous performance standards required for advanced RF, antenna, and microwave applications, ensuring flawless high-speed transmission.

Premium Multilayer High-Frequency FR4 PCB for Automotive Electronics
Customizable Stackup Configurations

Offering flexible layer counts (2 to 32+ layers), our high-frequency FR4 stackups are precision-engineered to accommodate complex routing requirements. This versatility allows the boards to be perfectly tailored to diverse form factors and the unique functional demands of space-constrained high-frequency equipment.

Automotive Grade Multilayer FR4 PCB for EVs with GPS and infotainment systems
Durability and Long-Term Reliability

Manufactured under stringent quality assurance protocols, our high-frequency FR4 boards exhibit outstanding thermal and mechanical stability. They are built to guarantee uninterrupted, long-term operation for critical RF, antenna, and microwave systems, even in the most demanding and harsh industrial environments.

Frequently Asked Questions

How do I know if I need Standard Tg or High-Tg FR4?
Standard Tg (130°C) is ideal for simple consumer electronics. If your PCB has 6 or more layers, operates in high-heat environments, or undergoes multiple lead-free soldering processes, High-Tg (170°C+) is strictly required to prevent via cracking and delamination.
Can FR4 be used for High-Frequency (RF) applications?
FR4 is highly capable for digital signals up to 2-3 GHz. Beyond that, significant signal loss occurs. We recommend our Hybrid PCB stackups—combining high-frequency Rogers cores with FR4 layers—to achieve microwave-level performance while maintaining cost efficiency.
What surface finish do you recommend for dense multilayer boards?
ENIG (Electroless Nickel Immersion Gold) is our standard recommendation for complex HDI/multilayer boards. It ensures a perfectly flat coplanar surface for BGA components and provides an excellent shelf life with high oxidation resistance.
