Isolation gap on a power PCB : Spacing on a power PCB
Spacing of common power PCB:
Double-sided PCB: 0.3mm; Single-sided PCB: 0.5mm; Module power supply & transformer input sideline: 1mm;
For those AC input but DC output power supply, safety spacing should be more than 6mm;
The radiator of switching power supply, spacing should be over 2mm.
