    Pcb versioning

    Hi, there is a convention for the pcb versioning?

    for example
    i have a first hardware realease
    in the second release i add a capacitor and a switch and minor changes on the silkscreen

    is correct something like

    first version
    v1.0 Rev A

    second version
    v.1.1 Rev A

    Schematics and pcb must they have the same nomenclature?

    As far as I know there isn't a convention. I use the following generally for my projects:

    vX.Y.Z

    I increment Z for changes that do not change a board's footprint (i.e. swapping a component for a different one of the same size, editing a trace, etc). These are changes that I want to track, but they typically do not change my manufacturing process - no need to change stencils or update placements. I increment Y for changes to my board's footprint and necessitate a manufacturing update. I increment X for a major change to a board that's intended to fulfill the same role (i.e. updated processors in a UAS flight computer - same role before and after the update and I intend the new board to replace the old board, so I keep the board name, but it's a major change).

    RE: schematics - when I move from prototype into production, my schematics are typically updated to track specific parts (i.e. a specific capacitor rather than just any 0.1 uF cap). I do this because I want my placement file to match my BOM. So yes, once I move into production, which is also when I start tracking v1.0.0, my schematic and PCB remain in lockstep.
