Leading the way for over 40 years
At the heart of complex devices where the PCB needs to be robust and reliable, lie high speed PCB design. Essentially, high speed printed circuit board design involves the process of balancing circuit board requirements, fabrication material, methodology and more, to create a PCB where signal integrity isn’t compromised. High Speed PCB design lends itself to miniaturization of devices as well as the increased rates of data transfer.
Characteristics of High-Speed PCB
The main characteristics with which you can identify a high speed PCB design include:
- Use of HDMI, Ethernet, SATA, PCI Express, USB, Thunderbolt, or other high speed interfaces for quick data transfer.
- Presence of multiple sub circuits that are connected through high speed interfaces.
- Digital frequency of 50MHz or more.
- Trace length which is 1/15 the wavelength of the signal.
- Small size of PCB.
High speed design involves paying due attention to a number of aspects so as to prevent noise generation, signal reflection, cross-talk and more. This includes:
- Evenly distribute power to reduce noise.
- Use the recommended routing techniques.
- Match impedance.
- Terminate signal and transmission lines so that signal reflection is diminished.
- Reduce cross-talk between arallel traces.
- Ensure the effects of ground bounce are reduced.
Similarly, the process of routing a board with high-speed signals involves looking out for:
- Properties and dimensions of board materials.
- The mechanical dimensions of the routes that can ensure controlled impedance.
- Quantity and arrangement of layers.
- Return path of high-speed signals.
- Configuration of vias.
- Controlling the route lengths.
High Speed PCB Guideline for Routing
- Focus on smaller trace length
- Focus on space between traces
- Proper use of length equalization
- Avoid use of large number of vias
Challenges While Designing High-speed PCB
There are a number of challenges when it comes to high speed PCB design. These include:
- Having tight tolerances with respect to board stackup, capacitance, length and width of marks, and more.
- Availability of high speed material to support signal speed, such as FR-4, Polyamide, PTFE
- Selecting the correct layer stack up, when it comes to multilayer boards.
- Board to board interconnections, and more.
