LTspice models - pcb traces and wires - resistance and tempco

[iMo]

I've been putting this into Metrology as I think people here could be interested..

Enclosed the models of "pcb Trace" and "Rwire" for playing with your designs, especially while chasing microvolts.

Inspired by an older Bordodynov library I made changes and put it here as .lib and .asy files. You may put it inside your LTspice and use easily 

Note the stuff could be improved - for example the fonts and the position of the attributes (and perhaps the models too), but I do not know how, you may tell me then.

Below a sim with the new symbols/models..

Mind the lengths, diameters, widths are in "meters" (like "100m" means 100mm==10cm), tempcos are related to 27C in the LTspice.

The copper pcb trace thickness is set to 35um.
