Using via's on a single layer pcb

    No, a via is a plated connection (small pad) that connects tracks on the top and bottom layer (plus other internal layers if they exist). If you are asking if you can use a via sized pad on a single layer then yes. You can use any pad size with any hole size that can be manufactured by you or a PCB manufacturer.
    But check prices if getting your boards produced, some suppliers do not produce single sided boards or their double sided boards may be the same price.

    Having said the above, what do you actually want to do with a via on a singled sided board?

    It's for a jumper or link between two tracks because of the single sided pcb constraints. The pcb is not that complex to warrant a double sided pcb and therefore links are used. I could have used pads as well I suppose.

    Yes, use a pad and set the sizes as required, turn off (uncheck) plated and that should work.

    You may want to try out using a double sided board but do all your routing (as much as possible) on the bottom side and only use the top for as few as possible short straight (again if possible) tracks.

    Produce your PCB from the bottom copper plot.
    The top copper shows where you will need to place your links.
    This technique has been posted in the forum by others.

    Boss,

    Thanks a lot for replying. I use a CNC milling machine to make my single sided pcb's but have never attempted double sided pcb's. I did a search with Google and on the forum but used via and single sided pcb for the search terms.

    What search terms would  you recommend on the forum for this topic?

    single sided DSPCB

    works pretty well in the search box.
