A high-speed circuit handles signals that switch quickly or operate at high frequencies, typically above 50 MHz, though some advanced systems may go into the GHz range. Best Technology is a one-stop PCB manufacturer that covers pcb design, pcb layout, pcb diagram, DFM, SI, PI analysis, PCB manufacturing and so on. In the following, you can see a high speed pcb design solution for industrial switch that we cooperated with our customer.
32 x 400GE industrial switch
[1]: Marvell-400G chip
[2]: 200A maximum current
[3]: Single pair differential line 56G optical network
[4]: 24 layers high power PCB
What’s the Best Material for High-Speed PCB Design?
Choosing the right material is vital for maintaining signal integrity and achieving optimal performance. The material impacts the board’s dielectric constant (Dk), loss tangent, and overall signal quality. Common materials include:
- FR4: Widely used but not ideal for very high frequencies due to higher loss tangent.
- Rogers (RO4000 series): Preferred for high-speed designs thanks to its low dielectric constant and loss tangent.
- Teflon: Excellent for high-frequency applications but more expensive and harder to process.
Selecting the appropriate material ensures the PCB can handle high-speed signals without compromising performance.
For the PCB design service, we can make sure the one-time success to save much time and money for customers. Our goal is to work with customers together and win more market with our clients. Just feel free to contact our technical team if you have similiar designs.
