Hi All,

In an effort to save my company some $$$ on PWB's I began investigating the cost of purchasing boards with and without specifying controlled impedance (on the PWB drawing). Almost all of our boards specify impedance control even if there are only a handful of transmission lines.

I was surprised to learn from the two fabricators I spoke with that there is no additional cost for impedance control other than a small cost adder of about 2-5% if all panels require testing. I found this very surprising.

Has anyone else had the same experience? Thanks much!

Regards,
Rick
