QUESTION FROM TIM in Ann Arbor, MI: You've mentioned through-hole vias and stubs, and their effects on high-speed serial links, but I don't recall your mentioning blind vias.
Designers can look at a copper-filled blind or through-hole via as another tool in their design tool kits to achieve their performance goals.
The loss for the worst-case through-hole via can be 10 times more than the best-case blind via with no stub.

All areas of blind and buried via testing, including defects per million vias, registration yields, coefficient of variation, and thermal cycling show significantly higher performance than the through-hole via test results from all suppliers.
