ISOLA 370HR High Frequency PCB Manufacturing and Assembly
♦ What's High-Frequency PCB?
A High-Frequency PCB is a specialized circuit board designed to carry signals in the radio frequency (RF), microwave, or millimeter-wave ranges (typically 500 MHz to 100+ GHz). These PCBs are engineered to minimize signal loss, interference, and distortion, making them critical for advanced wireless, radar, and high-speed digital applications.
♦ Key Features of High-Frequency PCBs
✅ Low Dielectric Loss – Uses materials with a stable dielectric constant (Dk) to reduce signal attenuation.
✅ Controlled Impedance – Precise trace geometry ensures consistent impedance (e.g., 50Ω or 75Ω).
✅ Low Signal Skew – Minimizes timing mismatches in high-speed signals.
✅ Thermal Stability – Resists performance drift under temperature fluctuations.
✅ Low Surface Roughness – Smoother copper reduces signal loss at high frequencies.
♦ Materials Used in High-Frequency PCBs
High-frequency PCBs require low-loss dielectric materials instead of standard FR-4. Common options include:
