Paul - What is the applicable product standard?
What type of product is it? What is the application? Is the 220V mains connected? From somewhere else in a primary circuit? Is the 220V in a secondary circuit? What levels of insulation are there between this circuit and other types of circuits elsewhere in the product? If in a secondary circuit, is it earthed? Is it a Limited Current Circuit? What other types of circuits are near it that require isolation/insulation on the board? Limited Current Circuits? TNV? SELV? ELV? Other hazardous voltage circuits? Regards, Peter L.
