  • Clearances

    A clearance (or isolation) is a term we use to describe the space from power / ground layer copper to through hole. To prevent shorting, ground and power layer clearances need to be .025” larger than the finish hole size for the inner layers. This allows for registration, drilling, and plating tolerances.
