BOT.Įach layer and component of your PCB uses a different file extension to keep everything organized. ![]() ![]() The primary file extension of Gerber files is. File ExtensionsĪt this point, you might be thinking, how do I know if I have Gerber files? One method is to take a look at the file’s extension. Although not widely used at this time, UCAMCO predicts it will become the new standard thanks to its compatibility with other programs and ease of application. UCAMCO recently announced another version called Gerber X3. It also streamlines the transfer of PCB designs from CAD to fabrication. These attributes are like labels that provide information about image files and their features. It’s compatible with most CAM applications and allows the user to attach attributes to the file. The newest version of Gerber is Gerber-X2, an extension of Gerber-X. It improved on the previous format by integrating the addition of metadata to graphics and images. Introduced in 1998, Extended Gerber is a human-readable ASCII format. It is generally out of use now, and the official Gerber website does not consider Standard Gerber files valid.Īn expanded version of Gerber is RS-274-X, also known as X-Gerber. Standard Gerber is the oldest form, also known as RS-274-D. Gerber file format has experienced many changes and updates over the years, so there are several versions of Gerber files.

In this way, it works as a kind of bridge between designers, engineers, and manufacturers.Įvery PCB design program can generate Gerber files, and every PCB fabrication software is able to understand them. Specifically, it is an open 2D binary vector image file format that is able to pass through every stage of the PCB manufacturing process. You might be wondering, what is a Gerber file and its purpose? The Gerber file is the standard file format used in PCB design.
