Hi
I have been designing 2-sided PCBs in Sprint Layout for years now and I am fairly conversant with designing straightforward circuits.
I want to design a 4-layer PCB, basically for the sake of it, but hoping to accreet knollege of how to do so, so I can use the knolledge should the circumstances arise.
I can generate the gerbers but I am at a bit of a loss when it comes to vias. Particularly vias that connect to power and ground planes.
If I want the via to connect to the ground plane do I need to put a 'hole' in the power plane so this doesn't inadvertantly short the two power planes out?
This and the opposite problem will take a lot of thought and I'm not even sure that I'm doing it right?
If anyone knows of a synopsis on designing 4-layer boards particularily in Sprint Layout that would be useful.
Or any observations, hints or helps, thanks in advance.
