Here's a handy online tool for determining PCB-trace separation: http://www.smps.us/pcbtracespacing.html There are 3 spacings noted (external, internal, and coated). I would recommend using 'external' wherever possible because it's the most conservative. Unseen flaws in PCB manufacturing happen, so using absolute-minimum spacing with high-voltage traces is a gamble.
The website mentions UL experiments that found PCB's can tolerate 40 volts/mil. One mm is about 40mils. I dont advise pushing PCB designs anywhere near that value, though. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
