Gerber File Extention from Different Software

Gerber files are files that all circuit design software can produce. They are also called stencil data in the electronic assembly industry, and light painting files in the PCB manufacturing industry. It can be said that Gerber files are the most common and most widely used file formats in the electronics assembly industry. Therefore, for an electronics manufacturing company, it is very important to have a computer-aided manufacturing CAM software that can handle Gerber files. It has the effect of assisting in improving quality by arranging production preparation, manufacturing, and testing processes.

Gerber file is the standard format of EIA and is divided into RS274-D and RS274-X. RS274-X is an extension file of RS274-D. The production and manufacturing department shall, as far as conditions permit, require the user or the design department to provide the Gerber file of RS274-X, which is conducive to the production preparation of each process.

Below shows the Gerber extensions generated by different commonly used PCB design softwares.
