What is Rogers PCB? What is the Difference Between It and FR4 PCB?
Ⅰ. What is Rogers PCB?
Rogers PCB is a special type of PCB made of high-frequency materials. PCB also has stable temperature and high-quality dielectric constant, which makes it stand out.
Rogers printed circuit boards have a thermal expansion coefficient similar to that of copper foil and are used to reinforce PTFE substrates. Rogers PCB is an ideal choice for high-frequency and high-speed circuits, as well as RF products and microwaves.
Rogers printed circuit boards are used in:
1. Telecommunications: cellular base station antennas, communication systems, direct broadcast satellites, microwave equipment, carrier-grade Wi-Fi/licensed assisted access, 5G stations, etc.;
2. Automobile: automatic test equipment (ATE), automobile sensors and radars, etc.;
3. RF engineering: power amplifiers, radio frequency identification tags, IP infrastructure, etc.;
4. Aviation technology: aircraft collision avoidance system, microstrip antenna, return radio, etc.;
5. Computer: DAS, Advanced Driver Assistance System (ADAS), etc.;
6. Military: interference system, radio communication system, etc.
Ⅱ. What is the difference between Rogers PCB and FR4 PCB?
1. FR-4 material of FR4 PCB is cheaper than Rogers material.
2. Compared with FR-4 material, Rogers material has a very high frequency.
3. The Df or dissipation factor of FR-4 material is higher than that of Rogers material, and the signal loss is greater.
4. In terms of impedance stability, Rogers material has a larger Dk value range than FR-4 material.
5. For the dielectric constant, the Dk of FR-4 is about 4.5, which is lower than the Dk of Rogers material (about 6.15 to 11).
6. In terms of temperature management, Rogers material has less changes compared with FR-4 material.
