     246==== Files Needed ====
    246247The following files are needed to make the board and attached to this page. Additionally the schematic is also provided as a reference.
    247248 * USB_mPCIx_Board.zip - These files describe the physical board. All fabrication houses should accept the gerber file format.
     
    255256  * USB_MPCIX_BOM.xls - Bill of materials, provides links and vendors for parts being used.
    256257  * USB_MPCIX_INSERT.TXT - mounting locations for the components on the board.

     259==== Fabrication and Population ====
     260The following set of instructions is specific to the production house WINLAB uses, [http://www.4pcb.com/ Advanced Circuits]. Other manufacturer may require additional information, however the process should be similar. [[BR]]
     261To have a board made the fabricated you must provide 'USB_mPCIx_Board.zip' as it contains all the physical board information. Typically this can be sent directly to a sales representative for quoting. If you intend for the boards to be populated, some manufacturers (definitely Advanced Circuits) require minimum quantities and dimensions, so you may request for the board to be panelized to meet those conditions. WINLAB had them produced 4 boards to a panel to meet Advanced Circuit requirements. Some additional information that might be required is as follows:
