strategies for high voltage on PCB, wire terminals

mw · 2005-05-07T10:24:07+00:00

Is there a book or link that gives some hints on properly designing a pc board so that it works well with ~100 VDC on the traces? I think that having this high voltage on the pcb will cause a break down of the board material (after several years). I want to prevent this. Is it as simple as using large spaces between the traces? Using conformal coating or varnish? Or is there a material other than FR4 fiberglass that is available?Also, I will want to attach a big transformer to the pcb and I know it is bad to run wires directly into a pcb because the solder can be brittle and this will cause the wires to be weak. It's also a hassle to unsolder for repair (the traces get ruined due to solder gun heat). So is there a terminal or "turret" like on tube amplifiers that can be used to protect the pcb? Or maybe this is a lot of worry about nothing. But I do want my power supply project to last for several years.Any ideas for a simple wire terminal to save the pcb? I don't want to use a connector because they can go bad after several years. Soldered connections seem simpler and more robust for longevity.

True, but you need a house to live in. If I sold my house, I could live in my car (or a tent on the beach, brrr) and smoke cigars and drink Jack Daniels for the rest of my life. Scary ;)
