Does anyone have idea about how to attach an AC line to a PCB board?
I have a transformer that is actually on the board itself. Is this a
good/bad idea? Do I basically drill a whole and stick the wire
through the hole and solder it one? I can't seem to find any
connector type stuff on digikey. Also, I plan to have a floating
ground on the other side of the transformer...i.e. electrical
isolation. Should any grounded part of the board be connected to the
netural line on the AC? Should there is some kind of connection such
as through a transient supressor? Any help is appreciated. Also,
should there be any type of noise supression on the AC side of the
board? What about grounding planes on the AC side? Thanks!
