Not Clearance & Creepage! The question is about the voltage from one layer to another.
I have a HV project where the voltage is 1750V at 400A.
Many of my power supplies run 24/7 for 10 years at high temperatures. For those I keep 1mm spacing between layers.
This project has a life span of 1 year and will probably only run for 100 hours at most.
PCB dielectric constant is 4.6.
Between layers 1&2 and layers 3&4 there are two layers of core totaling 0.18mm.
Between layers 2&3 there is a core of 1mm.
Copper is 2oz in all layers. High current traces use all 4 layers in parallel.
I really need to have 1750V d.c. from L1 to L2 for an area about the size of your thumb.
The HV a.c. traces do not get near other traces. The switching speed as fast.
Can someone do a sanity check on 1750V, 0.18mm spacing with a dielectric constant of 4.6.
Thanks. RonS.
