2.2.2.2 Line Arrangement Examples
Several dedicated tools are available to calculate line arrangements for specific applications
and PCB materials - for example from http://www.polarinstruments.com/ (commercial software)
or from http://web.awrcorp.com/Usa/Products/Optional-Products/TX-Line/ (free software).
Embedded Stripline
This figure below shows a line arrangement example for embedded stripline with 65µm FR4
prepreg (type: 1080) and 710µm FR4 core (4-layer PCB).
