Listed below are examples of the required fields on the files that we will need from you:
-Bill of materials (BOM) in CSV (or Excel).
-Copper, silkscreen, and solder paste layer gerbers in RS274X format.
-XYRS data file (Pick-n-place, component locator, or X, Y, rotation, side data – Centroid of parts)
We use custom software routines to read data from most CAD programs. However, normal usage has this data in a spreadsheet or a single line textual format.
1) Your BOM needs to provide the information in a machine-readable format.
The following is a XLS example which would work for us:
|Description||High freq NPO|
|Digikey Part Number(or MFG PN)||Capxxxx-ND|
2) Gerber layers: For any side with SMT parts we need three layers: copper, paste, and silk.
|Copper layer||for scaling|
|Paste||for stencil (note: not solder stop or solder mask)|
|Silk||Verification of the polarity of diodes caps and ICs|
3) The XYRS information would be based on component centroid (or Pin1) and used by our pick-n-place machine.
This information allows us to perform a quick and near perfect placement of our SMT components.
Although a CSV/XLS format is suggested for this information, we understand that various CAD programs will generate this in a ‘text’ format that is ‘standard’ (for a given CAD system). Some custom formats that we currently support include: PADs ASCII, Orcad Insert, and Eagle MNT.
The following is a usable example:
|Preferred Decal package||0805|
Note: A standard reference designator format is requested in order to work well with our input routines.
This format is comprised of letters followed by numbers. “CCCC####” (Examples: R1, Res0001, R9999, RArr0001)
