The Gerber format is a computer file format which is used by makers of printed circuit board (PCB) software. Information contained in a Gerber format file describes the printed circuit board to which it is associated, providing the computer with its parameters, including its solder, legend, and description. This information is like the blueprint of the printed circuit board, allowing the computer and software designers to know how and where to access the various sections of the board. Of the two general types — RS-274-D and RS-274-X — only the RS-274-X format is currently used.
Files with this format contain commands and coordinate data which allow the computer, and individuals programming for the computer, to fully understand the functionality and layout of the circuit board in question. Gerber format files are provided in American Standard Code for Information Interchange (ASCII) format, and are readable without the need for a translation program. In other words, the file is written in plain letters and numbers, not in binary or any other form which would be impossible for a human user to understand. There is software available that can display an image of the information contained in a Gerber format file.
