Files Required

Files Required

 Gerber files*

 Gerber files in format of RS-274X for PCB fabrication

BOM file*

BOM file in excel format for components sourcing and PCB assembly. It should include the components basic information: Reference Designators, Quantity, Part number, Description, etc. 

Click to download our BOM Template for reference.

Pick & Place file (if available)

Also known as Centroid file or XY data. It describes the position and orientation of all the surface mount parts and it can help us to quickly programming the SMT assembly machines.

Assembly drawing (if available)  

It includes the positions and polarities of the components designators which can help us better understand your assembly needs, correcting some ambiguous or even mistaken placements, and ends up with an excellent job

Testing Guide & Test Fixtures 

(if necessary)

To ensure the boards quality, we can test the boards following the provided testing guide & test fixtures before shipping.

Programming files & Programming tool 

(if necessary)

We could do IC programing for our customers if required.
