    Using CAD is almost mandatory these days to get a PCB made.  For two
sided PCB's, the minimum is probably:

    Top Layer Gerber Plot
    Bottom Layer Gerber Plot
    Top and Bottom Solder mask (assumes thru hole only, they will be the
same) opt.
    Top Legend (opt).

    Axelon (sp?) drill file
    Tool Table
    Fab Drawing (this can be in gerber format as well)
    Aperature List (for gerber files).

    Gerber files are a common file that is used to generate the film used to
manufacture the boards.  All PCB cad programs can generate these files.
    Drill files are very important.  Without the drill file, the costs will
go up astronomically.
