"WebSo if you have 115V difference between two conductors, clearance should be at least 23 mils. Unless your board needs to be ridiculously small for some reason, you shouldn't have a problem quadrupling that. If it still worries you, the PCB itself is an excellent insulator. Put the high voltage trace on the opposite side from the low voltage. " - High voltage trace clearance

Since a high proportion of parts are surface-mounted, it is possible to place circuits requiring clearance on opposite sides of the board.

WebThe traces (110V) have to be secured by a fuse in some way. The current of that fuse determines the thickness of the trace. That is the standard, and going with standards will save your ass if the device fails and there is a damage. Also, in case of a short between 110V and ground, a lower thickness will just burn away. WebConnector 1: VCC+ (5KV) Connector 2: VSS- (0V) With BV = 2.5KV for me it's clear that bringing the two connectors so close to each other the material will break. Maybe I'm wrong. I know the creepage and clearance techniques, but if I understood well it's referred to the sheet material and the copper over it, that has its own breakdown voltage/mil.
