Screw the board on a plastic surface and bend the plastic's surface edges upwards to cover the sides of the board.I soldered a lot of LEDs onto a circuit board, so the back of it has a lot of current-carrying wire and solder points that I need to insulate. What's the best way to insulate a circuit board?
Exactly! If it's in a plastic box, you're done. If it's in a metal box, you use standoffs. If it's in the open air and not getting warm, hot glue or epoxy over it. If it gets too warm for that (ie. melts the glue), use standoffs and put it in a box with holes and perhaps a fan.Perhaps we might ask: Insulate against what? If the PCB is not in contact with a conductor, then there is no need for insulation.
Use mineral spirits to smooth silicone. It doesn't react with the silicone and evaporates, but not quickly. Similar to water, do not apply power to a flammable liquid.if you're using a wet rag to smooth the silicone (before it forms a "skin"), allow the moisture to completely evaporate before applying power to the circuit!!!
