Hello. 2. Spacing for higher voltages. Again, look for online calculators/table > for creepage and clearance. There are various factors that affect spacing > including pollution levels. I always pick the most conservative rules I can > find. Spacing for 500V or less is pretty small, around 2mm. >
@gregebert Have you noticed, or is it documented in some standard, an effect on the spacing with respect to the silkscreen color? I use each project to refine my board design skills by imposing new challenges to myself and I have little experience with PCBs at >150V levels. So far I have been lucky and never had to go for a second round of the same design, also considering that I usually build a couple of each circuit but get 5 PCBs from the fabhouse... Anyway, on a Nixie design I had the feeling that the black silkscreen was "leaky" and the 180V on one line was pulling the one nearby. Is that possible, or I didn't respect the minimum spacing? I think I don't have that old KiCAD project anymore. TIA Paolo -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
