The ratio of board thickness to drilled hole diameter, impacting via reliability.

Sectional Standard for Design of PWBs for PC Cards Ipc-2221 Pcb Design Pdf

To prevent electrical arcing and short circuits, IPC-2221 provides definitive lookup tables for minimum spacing between conductors. These clearances are determined by: The voltage difference between the conductors. The ratio of board thickness to drilled hole

While IPC-2221 handles general spacing, high-voltage designs (like power supplies) must also reference standards like or UL 60950-1 to calculate exact creepage (distance along the surface of an insulating material) and clearance (distance through air). 4.
