What is the difference between high speed PCB and high frequency PCB?
High speed and high frequency pcb is different. High-speed circuit refers to that the voltage rises or falls in a short period of time, and high-frequency circuit refers to that the circuit has a short period. But there is no exact difference between a high-speed PCB and a high-frequency PCB. Even the basic materials are the same. So if you ask the difference between high-speed PCB and high-frequency PCB, ignore the name of the circuit board, and focus on how to maintain the signal integrity of the circuit.
Controlled Impedance applied into high frequency PCB
The design of controlled impedance line is to avoid the signal loss, there are two kind of method to set controlled impedance, that is microstrip and stripline: to support better result, the existence of the trace on the outer layers that come with a ground plane below must be closer to the outer layers. Stripline is better as compared to microstrip because it has an ability to contain radiation and signal.
The operating frequencies of high-frequency PCB
The high frequency PCB is often used to equip higher frequency where the use of traditional FR4 is impossible. The most important parameters of high frequency printed circuit board is:
- Constant dielectric: 2.0-10GHz
- Thickness criterial: 0.2-8mm
- Type of foil-clad material
