What’s High-Frequency PCB?
The high-frequency PCBs or microwave PCBs refer to the ones produced by a conventional rigid PCB manufacturing method on a specific high-frequency (>1GHZ) copper clad laminates.
In order to achieve high-speed transmission, it is necessary to achieve low loss and low delay of the signals, so copper-clad laminates that have low dielectric constant and loss are needed. Materials that can meet the requirements are such as ceramic, fiberglass, and PTFE (Teflon), among which, PTFE possesses the lowest dielectric constant (typically 2.6~2.7) and the dielectric loss tangent (0.002). It is the largest amount of materials are used to make high-frequency PCBs, which are mainly used in the fields of communications, medical, military, automotive, instrumentation, etc.
PS obtains raw materials from manufacturers that provide high-quality microwave PCB substrates, among which the famous ones are Rogers and Taconic.
