or high-frequency circuit board, refers to those specially designed for electromagnetic induction frequencies at higher levels.

 They are primarily used in high-frequency (frequencies exceeding 300MHz,

 corresponding to wavelengths less than 1 meter) and microwave (frequencies exceeding 3GHz, corresponding to wavelengths less than 0.1 meter) applications. 

These PCB boards are manufactured using standard rigid circuit board production processes

or special processing techniques on microwave radio frequency-grade copper-clad laminates.

Generally, high-frequency boards can be defined as circuit boards with frequencies reaching or exceeding 1GHz.
