    Hi there,

    I am just about to complete my PCB and am looking at adding some mounting holes to keep it off the ground.

    I am wondering do you just put screws in the holes to keep it of the ground or is there some kind of technical name off the device to do this?

    I have been coming across feet and spacers but not quite what i'm looking for.


    Its a trivial question but I don't know.

    Cheers

    hi Link,
    It depends on the appearance you want and the application.
    Is it a one off for home use or many off for resale.??

    You can use M3 screws, washers and nuts.
    Plain hollow spacers or M3 threaded spacers.
    Self adhesive plastic retainers

    EDIT:
    Check this link for options.
    I prefer the hexagonal, tapped internal thread and threaded stud.

    I just use a pieces of dowel (about 3/8" or 9 mm diameter x 3/4" long) attached with small screws or double-backed tape. Gives good clearance and doesn't scratch most surfaces.

    Believe it or not, I save the caps from toothpaste tubes for applications such as this. You can use them for cabinet feet or for small control knobs.

    There are two types on ebay etc really cheap.
    One is the PCB mounting feet, or the one I prefer is the Hex stand-offs, either in plastic or metal.

    If you were using an E3 screw with hex feet for example, would you need any special washers to avoid potential short circuit?
