差分对布线 What your Differential Pairs Wish You Knew with Rick Hartley

Rick Hartley's AltiumLive keynote on differential pairs in PC boards. He argues the rules from cables and twisted pairs do not carry over, and covers which pair geometry gives the best impedance control, the right spacing, routing practice and how much skew is acceptable.

Why HN likes it: HN engineers cite Hartley as the intuitive, field-based alternative to cargo-cult PCB advice, especially on differential pair routing, reference planes and EMI.

“this is absolutely worth your time if you design PCBs.”
