RF PCB Design Rules & Huihe PCB Manufacturing Guide

[Lisa You]

RF PCB Fundamentals
RF PCB (Radio Frequency PCBs) enable precision wireless systems (>100MHz), demanding strict RF PCB design to combat signal loss/EMI.

Critical Engineering Strategies
✓ Material Innovation
→ Hybrid FR-4/Rogers for cost-sensitive PCB RF
→ Ultra-low-loss laminates (Dk<3.0, Df≤0.002) for 5G/mmWave
✓ Layout & Shielding
→ 50/75Ω impedance traces via microstrip
→ Cavity shielding & via fencing for PCB RF power amps
✓ Signal Integrity
→ Grounded coplanar waveguides
→ MATLAB S-parameter simulation

Manufacturing Excellence
Top RF PCB manufacturers like Huihe PCB deliver:
・ Laser-drilled microvias (HDI boards)
・ ±0.15mm tolerance RF connectors
