When the transition of FR-4 PCB materials to higher performance materials is usually not as simple as people can imagine. When the transition is obvious, many unexpected problems may need to be solved. Some of these problems may be related to circuit design, others may be related to PCB manufacturing process.

Radio frequency is referred to as RF, radio frequency is the radio frequency current, it is a kind of high frequency alternating current electromagnetic wave abbreviation. Alternating current that changes less than 1000 times per second is called low-frequency current, and that greater than 1000 times is called high-frequency current, and radio frequency is such a high-frequency current.
