对于可选的高频阻抗控制应该考虑什么？
What should be considered for optional high frequency impedance control?

在本段视频中，John Coonrod讨论了PCB电路阻抗控制涉及的诸多变量。对于每个变量，比较了其对阻抗的影响程度，可让设计者关注设计中对电路阻抗产生不同影响的特定变量。
In this video segment John Coonrod discusses the many variables involved with impedance control for Printed Circuit Boards (PCB’s). Comparisons are given for the magnitude of influence for each of these variables, which allows the designer to focus on specific aspects of a design that can have more or less effect on the circuit impedance attributes."
