    FR4 is often used in all the kind of electronics - including 230V circuits. PS: Saturn PCB can help you to answer more questions (the software is free):

    Nope! No nead to worries about breakdown there.. Used it plenty of time for 220v. But keep large space between AC pairs and DC..

    Hi Guys,

    I am interested in getting some number about break-down voltage in FR4, should we need to worry about 100V? can it cause break-down?

    Regards,
Working...
