IPC2221B PCB Trace Spacing / Clearance by Voltage

PRINTED CIRCUIT BOARD (PCB) SPACING / CLEARANCE vs. VOLTAGE. One would think that UL norms should be most stringent than IPC. However, it is interesting to note that when it comes to functional insulation in secondary circuits, UL requirements are not necessarily more stringent than IPC. See our calculator and guide to PCB creepage vs. voltage for a comparative analysis of different IPC .
