For PCB Manufacturing or quotation , You need send us Gerber RS-274X files to check.
Below please find the instructions you’ll need for submitting your Gerber files to us for production of your printed circuit boards. If you need assistance, our customer service representatives can help you determine all of the file types you will need to submit for your PCB order.
Gerber File Format and ODB++ File Format
Gerber File Format
Gerber is an open ASCII vector format for printed circuit board design that shows parts of a board like copper layers, solder mask design, etc. Many applications can read this format because it simple, has detailed specifications, and has few bugs because of its wide use and subsequent debugging. The simple format of a Gerber means it is easy to identify and fix bugs as well. There are three Gerber generations: Gerber X2 (current format), Extended Gerber, or RS-274X, and Standard Gerber, or RS-274-D, which is now obsolete. The Gerber X2 format contains layer stackup information, which was not in previous versions. Software that supports the X2 format will read and identify each item's function in the file.
A RS-274X file contains the complete description of a PCB layer image without requiring any external files. It has all the imaging operators needed for a PCB image. Any aperture shape can be defined as well as positive and negative objects. Planes can be specified without the need to 'paint' or 'vector-fill' as in RS-274-D.
RS-274X is a complete, powerful and unambiguous standard to describe a PCB layer. It can be input and processed fully automatically. This makes it well suited for fast and secure data transfer and for reliable and automated workflows.
Remember to include the following when submitting Gerbers:
All copper layers (inner & outer)
Soldermask layers
Silkscreen/legend layers
Via plugging layers (if applicable)
Solder paste layers (for assembly)
Aperture list if apertures are not embedded in Gerber data
Trijicon serial number lookup. During the PCB layer assignment in our Auto File Verification, you will have to tell us which gerber file is which layer. This table will help you for some common packages.

ODB++ File Format
There has been a lot of debate between whether Gerber format or ODB++ formats are better for PCB design. Some designers and shops prefer one format over the other. At Sierra, we prefer ODB++ formats. Here's a summary of both formats and their pros and cons.
ODB++ stands for Open Database and serves as a way to exchange data between computer-aided design (CAD) and computer-aided manufacturing (CAM) formats for circuit boards. This format was first introduced as ODB, and the '++' was added after a new version included components. ODB++ is an ASCII file that has all the information pertaining to the circuit board design. Printed circuit boards are designed in CAD and transferred into CAM. CAD and CAM programs are usually made by different companies, so they need to agree on the type of data exchange. ODB++ is a manufacturing-oriented program. Many shops prefer this format for this reason because one file can consolidate all the information needed for the job, whereas some Gerbers need additional information from several files to make sense of the image layers. This eliminates the need to analyze each file to eliminate bugs.
| ODB++ | Gerber | ||
|---|---|---|---|
| Pros | Cons | Pros | Cons |
| One file includes stackup, layers, drilling, masking, net data | Different image format | Simple | Multiple files needed |
| Widely used | More complex format than Gerber | Widely used | Requires examination of all files at fabricator |
| Undergoes DFM / quality checks | Specification is precise | ||
| Easy to transfer to fabricator | Format supported by free viewers | ||

Software Overview
Main Features
- Cross-platform PCB design program
- Design tools for layout of PCB electronic components
- User Language Program (ULP) functionality enables custom features
- Export PCB design to Gerber format
Autodesk EAGLE is a CAD application used to design the layout of a Printed Circuit Board (PCB). EAGLE stands for “Easily Applicable Graphical Layout Editor.” It is available for Windows, OS X, and Linux. Autodesk EAGLE was formerly known as CadSoft EAGLE.
EAGLE allows you to create the layout of electrical wires, central processors, and other electronic components on your PCB. The application offers Schematic Editor, Layout Editor, Library Editor, and Autorouter modules to help you design your PCB. You can use these modules to modify different elements of your PCB, such as layers, reference points, and object properties. The program includes other features such as self defined commands, simulation, and data import and export functionality.
EAGLE also provides User Language Program (ULP) functionality. ULPs are programs that EAGLE can execute to modify internal data, instruction sequences, and produce data. They are similar to plugins, as they add user-modified functions to EAGLE. ULPs use the .ULP file extension and are available for download on the Autodesk EAGLE website.
Autodesk EAGLE is a useful PCB CAD application. It provides tools to design your PCB and supports ULP functionality. If you are a professional or just a hobbyist, you will most likely find Autodesk EAGLE up to the task.
