I ask for help PCB designers,who has succesful experience with High Voltage (until 5 kV) PCBs.
1. Minimal distance between conductors with and without coating, depending on
Voltage.
2. What coating is most common and recommended for HV boards.
3. The 2 sided board (FR4) thikness depending on voltage between layers.
4. References to appropriate materials in the net.
5. Anything else.
For example, our matufacturer used a material "Epoxidharz Araldit F" from CIBA GEIGY. But I affraid it will be useless for you. During transition from development to manufacturing I just asked manufacturer for some suitable material.vdaniel said:There are a lots and lots. That is why I am asking for standard and proven one.
