Understanding Via Impedance
If you routinely give attention to trace impedance but are not accustomed to thinking about via impedance, this post is for you. Or, if you are paying attention to via impedance yet are unsure what dimensions will yield the right impedance, this help with that too. So, when should I use an 8 mil drill? Why should I care? Serial links can fail because of impedance miss-matches discontinuities . In practice, discontinuities are likely causing more problems than loss. While loss degrades a signal s...
