PCB Assembly Quote Required File

1.     Bill of materials (BOM) in CSV or Excel format ------ PCB Assembly Quote Need

2.     Copper, silkscreen, and solder paste layer gerbers in RS274X format ------ PCB Assembly Quote Need

3.     Pick and place file or XYRS data file (Pick-n-place, component locator, or X, Y, rotation, side data – Centroid of parts) ------ PCB Assembly Need


1) Your BOM needs to provide the information in a machine-readable format. The following is a csv/xls/.xlsx example which would work for us:

Reference Designator(s) Value Description Digikey Part Number (or MFG PN) Decal/package/Footprint (Optional)
C2,C6-C8,C11-14,16 .1uF 50V High freq NPO Capxxxx-ND 0603


2) Gerber layers: For any side with SMT parts we need three layers: copper, paste, and silk.

Copper layer for scaling
Paste layer for stencil (note: not solder stop or solder mask)
Silk layer verification of the polarity of diodes, caps, and ICs.


3) Pick and place file or 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.

Reference Designator(s) X Y Rotation Side (Preferred) Decal/package
C1 2.850mil 1.650mil 90 TOP 0603

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.
