Product Specification

4-Layer HDI PCB for RFID | High-Gain RF Interconnect Solution

Product Overview:

Our 4-layer HDI PCBs are optimized for high-gain RFID readers and active smart tracking systems. By utilizing a sophisticated 4-layer stack-up with precision micro-via technology, we provide superior electromagnetic shielding and low-loss signal paths essential for long-range RF communication. These boards are designed to support complex NFC controllers and multi-protocol RFID modules in a compact form factor. Featuring excellent dielectric stability, our HDI boards ensure consistent antenna performance and high-speed data processing for industrial IoT and secure access control applications.

Key Selling Points:

• Enhanced Range: 4-layer shielding for superior RF signal gain.

• Compact Layout: High-density micro-vias for small-footprint designs.

• Low Interference: Optimized stack-up for minimized EMI/EMC noise.

Engineering Support: DFM (Design for Manufacturing) check before production.

Testing: Flying Probe Test, Fixture Test, Impedance Control Test, Thermal Stress Test.
