previously I made discrete board design using Orcad V16.0 tool.
But now plan to SMD based board design using design.
Generally what i was doing for discrete PCB board in Orcad as follows:
pad to pad 8mil
pad via 8mil
pad to track 8mil
track width .8mm
I heard that there is a rule for track width According to that track width will be set?
what is the Rule ?
How it is applicable for through hole component as well as for SMD on?
How should be the consideration taken for both the cases as for the rule?
