230VAC voltage and 4 layers PCB

[dexter_04]

Hi everybody,

I'm routing a 4 layers PCB with 230VAC. I've found some documents about spaces between tracks on external layers / inner layers / coated / uncoated.

But I didn't find any documents about insulation between layers. Because, I'd like to put some of 230vac tracks on inner layers but I didn't know if the tickness of prepreg will be enough between main and neutral for exemple (Can I put 230VAC on inner 2 and neutral on bottom for example).

If someone has some answers, documents about it, I'll be very happy !

Maybe, I've found some informations :

High Voltage Multilayer PCB

I want to design a four layer PCB, where on the top and second layer are voltage up to 600V present. While I find many information about trace spacing, I don't find anything about isolation between...
