You could contact the guys at Introbotics. www.Introbotics.com They had a huge part in the writing of the 2.5.5.7
document and are extremely knowledgeable on the subject.

For field solvers, Polar is probably the most common and popular. There's also Apsim Technology (my preference), but the
UI is coarse.

In a former life, I was a Process Engineer for a Controlled Impedance Test department. If you'd like, give me a call and
I'll see if I can answer any questions for you.

Subject: [TN] controlled impedance


TechNetters, can anyone assist me with understanding controlled impedance measurements on unpopulated PCBs? I have
looked at TM-650, method 2.5.5.7. If anyone with experience in making controlled impedance measurements could contact
me, I would appreciate it greatly.
