• Reference Designator
• Description
• Package Type (footprint)
The Microsoft Excel format (.xls, .xlsx, .csv, or tab-delimited) is required for the Bill of Materials (BOM).

We need the files in the Gerber RS-274X format.

For assembly, we need at a minimum:
• Silkscreen
• Copper (trace layers)
• Solder paste layers
Preferably, as if you were sending them in for fabrication, you should send us all Gerber files generated by your CAD program.
