A Gerber File is a standard file format used by printed circuit board (PCB) fabrication houses that contains data necessary for computer controlled machines to draw exact patterns for circuit boards. Most of today’s Gerber files are generated according to the RS-274X Gerber format, which supersedes obsolete formats such as the RS-274-D Gerber standard. It’s a 2-D ASCII file format that was originally designed for the now deprecated photoplotters which used to be mainstays of the PCB manufacturing process. The Gerber file is a standard format defined by the EIA with two different types: RS274-D and RS274-X. View Gerber files online for free. The original Gerber format was the EIA RS-274D standard, which consisted of a command file for each conductive layer and a tool description file. With a long history behind it, Gerber file viewer data continues to grow and evolve as design needs become more complex. Extract drill data from Gerber and DXF files. It consists of commands and coordinates for drawing lines and predefined shapes. There are 2 major generations of Gerber format: Extended Gerber, or RS-274X.
