PCB Assembly Files Explanation

If you need to place an assembly order in NextPCB, you should ready the PCB file, BOM list, and Pick & Place file. Without one of them, it is hard to go through the assembly process.

What is PCBs file?

PCBs file is a design file for PCB fabrication, testing, and stencil production. It will also be used to test the boards after soldering is completed. PCB files should be provided when you need PCB assembly services. We accept the Gerber file (RS-274-X),.PCBDOC, PCB, Eagle file and etc.

What is the Bill of Materials (BOM)

The Bill of Materials is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product. A BOM may be used for communication between manufacturing partners or confined to a single manufacturing plant.

We could help you to source the components according to the BOM which was offered by your side.

BOM Sample: If you need to order PCB assembly order in NextPCB, please give us the BOM list as BOM Sample.


What is Pick & place machine placement data?

Pick & place machine component placement data is very important in the PCB Assembly process. It will be used for setting Pick & place machine. there will be columns for:

1. Surface Legend (top or bottom)
2. X/Y coordinate of the center of the part (centroid data)
3. Part number
4. Rotation (theta)
5. In order to assemble your PCB smoothly, you could offer us some documents like 3D design files, schematics, etc. to guide our PCB Assembly process.

Pick & Place File Sample: please send us to pick and place file when the order assembly project to us.
