And also, today's dumb question:
I know that spacing between traces is governed by voltage and the
width is governed by current load and temperature rise above ambient.
If I use a 12 mil wide trace, can I still maintain an 8 mil wide
space to the next trace? Assume it meets the spacing for that
voltage. Or is the spacing always at least track width?
********my reply....
I believe that the width of trace and width of 'airgap' are independent of each other. The 'airgap' should solely rely on the voltage potential between two traces. I would guess that it is just a convenience for the PCB vendor to have both specs the same.
