ISOLA FR408 High Frequency PCB

For general frequency, use FR-4 sheet, but high-frequency materials should be used in the frequency ratio of 1-5G, such as semi-ceramic materials. ROGERS 4350, 4003, 5880, etc. are commonly used ... If the frequency is higher than 5G, it is best to use PTFE material, which is polytetrafluoroethylene. This material has good high-frequency performance, but there are limitations in the processing arts, such as the surface technology that cannot be hot air leveled. The following is about ISOLA FR408 High Frequency PCB related, I hope to help you better understand ISOLA FR408 High Frequency PCB.
