hi

How do you set the layer thickness? std thickness
and Impedance matching and how to calculate
impedance in Powerpcb v3.

With Regards

You set all that in /Setup/Layer Definition......Click on Thickness and set your layers.

This is a nice program, especially the layer stackup. Too bad it only goes up to 12 layers. Does anyone know if the fullblown version has more layers or is this it? And if not, where can this be bought at, i searched the PCBstandards store and did not see it.

The tool was never designed with the intention of being sold.
How many Layes do you Require.
I'm updating the tool so i'll try to Fit this in for you.

well 40 would be cool. but that is the maximum we have done, with the average being 24-30 layers for the last several months.

Thanks in advance!

Gulp..........40!

I just haven't got the time at the moment to make such a big modification.
If it was 2 or so Layers extra I would have done it.
I will keep the 40 Layers in mind in the event of a quiet Period but i can't see it happening for some time.

Sorry
