♦ What's High-Frequency PCB?

High-frequency PCB is a special circuit board designed for high-frequency electromagnetic scenes, suitable for high-frequency (frequency>300MHz, corresponding to wavelength <1 meter) and microwave (frequency>3GHz, corresponding to wavelength <0.1 meter) fields. It is based on microwave substrate copper clad laminate, combined with some processes of ordinary rigid circuit board manufacturing, or made through special processing.

♦ Features of High-Frequency PCB

• • Special materials: use low Dk/Df substrates such as PTFE, ceramic filling materials, LCP, etc. to reduce signal attenuation (PTFE is the first choice for 5G).

  • Precise transmission: impedance control of ±5%, micron-level line accuracy, 30%+ loss reduction in millimeter wave band, and excellent phase stability.

  • Complex process: laser drilling accuracy of ±3μm, plasma etching instead of pickling, multi-layer board integrated passive devices, and high-yield production in dust-free workshops.

  • Strong heat dissipation: metal substrate + thermal simulation + phase change material, adapting to extreme environments from -55℃ to 125℃.

♦ High-frequency PCB design principles

• • Material selection: low Dk (such as PTFE), low Df materials, matching frequency requirements, taking into account thermal stability and copper foil bonding.

  • Wiring rules: 45° routing, equal-length differential pairs, short and straight paths, control line width/spacing, reduce crosstalk and reflection.

  • Power ground design: multi-layer board power/ground layers are adjacent, decoupling capacitors are added nearby, and analog/digital ground is isolated by partition.

  • Stacking structure: 4 layers or more are preferred, and the middle layer is used as the power/ground plane to reduce parasitic parameters and shorten the signal path.
