High-Frequency PCB - No Radio Signal Delay or Loss Anymore

high frequency pcb 1

Overview of High-Frequency PCB

  • High-frequency (HF) PCBs are special printed circuit boards to transmit and receive high radio frequency signals. HF PCBs include the radio frequency printed circuit boards (RF PCBs) and the Microwave PCBs, and they are usually in a multilayer stack. Though high-frequency PCBs are extremely complex, PCBONLINE will assist you in every step in the PCB project, and manufacture the best HF PCBs/PCBA (including RF PCBs and Microwave PCBs) at your request.
  • With the advent of new technologies such as the 5G and the millimeter wave technology, high-frequency PCBs are used in almost every filed concerned communication signals, including consumer electronics, military/space, high power applications, medical, automobile, and industrial.

Requirments for Materials

High-frequency boards have very many requirements for the materials:

  • 1. High frequency PCB must use low water absorption of the substrate if use high water absorption will be affected by moisture dielectric constant (Dk) and dielectric loss (Df).
  • 2. The thermal expansion coefficient of the high speed high frequency PCB substrate and copper foil must be consistent, otherwise, it will cause copper foil separation.
  • 3. High frequency signal PCB substrate dielectric constant (Dk) must be small and stable. Generally speaking, the smaller the better, because of the signal transmission rate and the square root of the material dielectric constant is inversely proportional. The high dielectric constant is easy to cause signal transmission delay.
  • 4. PCB for high frequency substrate material dielectric loss (Df) must be small. Dielectric loss (Df) mainly affects the quality of signal transmission, the smaller the dielectric loss, the smaller the signal loss.
  • 5. High frequency PCB materials also require high heat resistance, chemical resistance, impact strength, and peel strength
  • 6. The impedance control requirements of finished PCB wires are strict.
