B. WHAT IS GEBRER FILE

    The Gerber format is a file format used by printed circuit board (PCB) industry software to describe the images of a printed circuit board (copper layers, solder mask, legend, drill holes, etc.). The Gerber format is the de-facto industry standard for printed circuit board image transfer.The Gerber format specification can be freely downloaded.

    There are two versions. RS-274X ("extended Gerber") is the most commonly used today. The previous version was a subset of EIA RS-274-D ("standard Gerber"); it is deprecated and is largely superseded by RS-274X. RS-274X is an extension to RS-274D. Gerber files generated in RS-274D lack aperture information, while RS-274X embeds aperture information, .274D files need to have the aperture definitions entered manually.

    The Gerber format was developed by Gerber Systems Corp., a company founded by Heinz Joseph “Joe” Gerber.he format is now controlled and owned by Ucamco through its acquisition of Barco ETS, a company that previously acquired Gerber Systems Corp.
