Hi, I plan to work with 600VDC, both on a PCB and off it. Now my PCB will have 600V and logic 5V circuitry, and i'm scared of creapage. Right now i have it designed for 3mm distance between signals on same layer of FR4, and no traces above or below, I'm hoping thats good enough. But on the top of the board, to bring the 600V onto it, i'm using these connectors (http://www.erni.com/powertapfront.htd), The connectors for the 600 and 600 gnd are about 3inches away from each other, but about 3mm from the 5V circuitry. I got that from this chart , http://www.smpspowersupply.com/ipc2221pcbclearance.html , which is good for 1000V on external component leads, uncoated. So, that connector being 3mm away from a resistor lead carrying 5V, should be okay, if i'm not mistaken? And would that distance apply for off PCB stuff too. Cus I have two bus bars, one carrying the 600V and the other 600 Gnd, spaced 2 inches away from each other, and i'm worried about arcing. Any help is greatly appreciated,
Thanks,
Jim
