BOM & CPL Data


The Assembly process requires a data set for the PCB production plus BOM & CPL data.

For Input data requirements for the PCB production process, please see this.

BOM (Bill Of Materials)

lists all the different parts for a single PCB. This file defines the parts by Description, MPN (manufacturers part number), SPN (suppliers part number) and cross references it to the Reference Designators (R1, C2, IC3 etc) on the PCB. Of each part there may be one or more components placed on the board.

It is also known as the Parts List.

The CPL (Component Placement List)

This file specifies the exact position, rotation and on which side of the board each component reference designator needs to be populated.

Alternative names for the CPL file are Pick and Place file, Centroid file, XY file or Position file.
