Sreekanth,
The best way to do this is to refer to the voltage impulse tables in IEC
60664-1 and determine the impulse rating required for your 1kV working
voltage. Then divide the V/mil rating into that number.
Simply dividing the 1000 volts by the V/mil rating of the prepreg is
risky at best because all electrical products experience voltage
impulses unless on a battery supply.

Subject: [SI-LIST] Voltage & Prepeg thickness
Hi All,
What could be the rule of thumb while designing a multilayer
board with HighVoltage.
For eg:- If I have 1KV in one layer, what could be the
required
minimum prepeg thickness to the next layer?
And what could be the voltage & current carrying capacity
of
FR4 .
BestRegards,
Sreekanth N Nampoothiri
