Rogers 5880 High Frequency PCB Board&PCBA

High frequency circuit board is a special circuit board with a high electromagnetic frequency, in general, high frequency can be defined as a circuit board with a frequency above 1GHz. PCB in the field of microwave (frequency greater than 3GHZ or wavelength less than 0.1 m) is a circuit board produced on a microwave substrate copper clad plate using part of the ordinary rigid circuit board manufacturing process or using a special treatment method. Its physical properties, accuracy and technical parameters are very high, and it is often used in automotive anti-collision systems, satellite systems, radio systems and other fields.

With the rapid development of science and technology, more and more equipment is designed in the microwave frequency band (> 1GHZ) and even in the field of millimeter wave (77GHZ) above the application (such as the vehicle 77GHz millimeter wave antenna is now very popular), which also means that the frequency is getting higher and higher, and the requirements for the substrate of the circuit board are getting higher and higher. For example, the substrate material needs to have excellent electrical properties, good chemical stability, and the loss on the substrate is very small with the increase of the power signal frequency, so the importance of the high-frequency plate is highlighted.
