The four files you need to provide us for proceeding with PCB Assembly are,

1. Gerber File of the PCB.

2. BOM File (Bill of Materials) with designations & quantity.

3. Pick&Place File. it is used by our automated SMT Assembly machines to determine the location of each component.

4. Orientation files/images-This is required to place the components like connector, diodes, Integrated circuits,etc. in the correct orientation.

Gerber File:

The Gerber format is an open ASCII (American Standard Code for Information Interchange) vector format for PCB designs. It is the very first input which a printed board manufacturer needs. We will have this file if your PCB was made with us.

Components of a Gerber file,
