If you have more requests or question please leave your note when you are uploading your file on eecart.

Gerber Files

We need the same Gerber file as you order PCB fabrication.

The Gerber file need at least three layers:Silkscreen,Copper and Solder Paste.

Our staffs at eecart will check the accuracy of information, DFM(design fro manufacture) before the assembly.

CPL File

CPL file is a necessary document we need for programming the assembly machines.

It is also called PNP(Pick And Place),XY Data or Centroid.

It describes the position and orientation of all the surface mount parts, which includes the reference designators, X and Y position, rotation and side of Board.

Usually most of PCB design software like AltiumKicad or Cadence,they will create the CPL File automatically,anyway there are still some software that do not support this function.

For more accurate assembly process,please send us more documents that are related to PCBA such as special assembly requirement,assembly drawing etc.

This will help us have a better understanding about your projects and will lower defect rate significantly.

So have some boards to assemble? Please send your files to us ASAP
