Explanation

This question evaluates your expertise in designing printed circuit boards (PCBs) for high-speed circuits while addressing signal integrity and electromagnetic interference (EMI). Recruiters want to see your knowledge of PCB layout tools, material selection, and design rules. A strong answer includes specific techniques, considerations, and examples of successful design. Avoid vague responses or failing to address critical aspects like crosstalk or impedance matching.

Answer Example

I ensure a successful high-speed PCB design by focusing on trace impedance control, minimizing crosstalk, and adhering to design-for-manufacturing principles. For example, I used Altium Designer to create a multi-layer PCB for a 10 Gbps data transfer system, carefully routing differential pairs and including proper ground planes. This minimized signal degradation and achieved EMI compliance during testing.
