RF is the abbreviation of Radio frequency, which indicates the electromagnetic frequency that can be radiated into space. The frequency range from 300khz to 300GHz. Radio frequency is radio frequency current, referred to as RF, it?s short for a high frequency alternating electromagnetic wave. An alternating current that changes less than 1,000 times per second is called a low-frequency current, and more than 10,000 times is called a high-frequency current, and radio frequency is such a high-frequency current. Radio frequency (300k-300G) is a higher frequency band of high frequency (greater than 10K), and microwave frequency band (300M-300G) is also a higher frequency band of radio frequency.
In the theory of electronics, current flows through a conductor, and a magnetic field is formed around the conductor; An alternating current passes through a conductor, and an alternating electromagnetic field is formed around the conductor, called an electromagnetic wave. When the electromagnetic wave frequency is lower than 100kHz, the electromagnetic wave will be absorbed by the surface and cannot from an effective transmission, but when the electromagnetic wave frequency is higher than 100kHz, the electromagnetic wave can be propagated in the air and reflected by the ionosphere at the outer edge of the atmosphere, forming a long-distance transmission capability.
First let's take a look at the material data sheet from the Rogers website:

PCB pressing structure
ROGERS3010 and 3003 mixed pressing
ROGERS6002 and 6010 mixed pressing
Lamination parameter control:
Heating rate: 2.5-4 degrees / minute
Curing temperature: 245-250 degrees, need 120 minutes
It's different from ordinary PCB pressing,it?s recommended to heat press for 3 hours.
