When designing a PCB for high-frequency applications, which of the following factors is paramount in controlling characteristic impedance and minimizing signal reflections?
Question 2
In the context of PCB design, what is the primary purpose of implementing a 'guard trace' or 'guard ring' around sensitive analog signals or high-speed digital traces?
Question 3
When routing differential pairs for high-speed signals, what is the most critical design rule to ensure common-mode noise rejection and maintain signal integrity?
Question 4
In PCB manufacturing, what is the significance of the 'aspect ratio' of a drilled hole, and why is it a critical DFM consideration?
Question 5
When designing a PCB for power delivery networks (PDN), what is the primary reason for using multiple vias to connect a power plane to a component's power pin?
