Pcb Gerber Viewer For MacGerber format Wikipedia. The Gerber format is an open. ASCIIvector format for 2. D binary images. 1 It is the de facto standard used by printed circuit board PCB industry software to describe the printed circuit board images copper layers, solder mask, legend, etc. Gerber is used in PCB fabrication data. PCBs are designed on a specialized electronic design automation EDA or a computer aided design CAD system. The CAD systems output PCB fabrication data to allow fabrication of the board. This data typically contains a Gerber file for each image layer copper layers, solder mask, legend or silk Gerber is also the standard image input format for all bare board fabrication equipment needing image data, such as photoplotters, legend printers, direct imagers or automated optical inspection AOI machines and for viewing reference images in different departments. For assembly the fabrication data contains the solder paste layers and the central locations of components to create the stencil and place and bond the components. There are two major generations of Gerber format Extended Gerber, or RS 2. X. This is the current Gerber format. In 2. 01. 4, the graphics format was extended with the option to add meta information to the graphics objects. Files with attributes are called X2 files, without X1 files. Standard Gerber, or RS 2. D. This obsolete format was revoked. It no longer conforms to the Gerber format specification and can therefore no longer be called a Gerber format. The standard file extension is. GBR or. gbr1 though other extensions are also used. PCB fabrication dataeditPCBs are designed on a specialized electronic design automation EDA or a computer aided design CAD system. The CAD systems then outputs PCB fabrication data to allow fabrication of the board. Fabrication data contains a Gerber file for each image layer and drill span copper layers, solder mask, legend or silk. Excellon format is also used for drilled hole information. Typically, all these files are zipped into a single archive that is sent to the PCB bare board fabrication shop. The fabricator loads them into a computer aided manufacturing CAM system to prepare data for each step of the PCB production process. The. File. Function attribute is the standardized method to link each layer in the PCB with its corresponding Gerber file in the fabrication data. If attributes are not supported only informal methods are available. A simple informal method is to express the file function clearly in the file name. Sometimes the file extension is abused to indicate the file function e. BOT for the bottom layer rather than the standard extension. GBR. This is very impractical as the customary link between format and extension is lost. PCB Fabrication Data must comply with a number of rules all layers must be aligned, a profile layer must be included, etc. The CAD netlist can be embedded in the Gerber files. However, for historic reasons, netlists often are described in a separate file in IPC D 3. A, an electrical test format. The material stack up, components and finishes are typically provided in informal text files or drawings. Ucamco has published a draft specification to include fab documentation in Gerber for public review. Extended GerbereditRS 2. X, extended Gerber or X Gerber, was originally released in September 1. It is a human readable ASCII format. It consists of a stream of commands generating an ordered stream of graphics objects. The graphics objects can be positive or negative. Superimposed in the correct order they create the final image. A Gerber file contains the complete description of a PCB layer image without requiring any external files. It has all the imaging operators needed for a PCB image. Any aperture shape can be defined. Magix Music Maker 2013 Premium Keygen on this page. Planes and pads can be specified without the need to paint or vector fill as in Standard Gerber. However some implementations still use painting, problematical for the users of those files. Adobe Acrobat X Pro Warez. Released in February 2. Gerber X2 adds additional metadata to the image. Attributes allow to add metadata to a Gerber file. Attributes are akin to labels providing information associated with image files, or features within them. Examples of metadata conveyed by attributes are The function of the file. Is the file the top solder mask, or the bottom copper layer, etc. The part represented by the file. Does it represent a single PCB, an array, a couponThe function of a pad. Is the flash is an SMD pad, or a via pad, or a fiducial, etc. For more information about attributes see X2 FAQ or intro video in the external links. An example of a Gerber file.

Standard Gerber revokededitStandard Gerber was a numerical control NC format designed by Gerber Systems Corp to drive their vector photo plotters for the PCB industry in the 1. It was a subset of the Electronic Industries Association. RS 2. 74 D specification,2. NC machines in a wide range of industries. The term RS 2. 74 D, without the qualifying Gerber postfix, is sometimes used informally for standard Gerber. Standard Gerber became the de facto standard format for PCB images. Standard Gerber was a simple ASCII format consisting of commands and XY coordinates. An example. X1. 78. Y2. 17. 39. 80. D0. X1. 79. 66. 50. Y2. D0. 1 X1. 78. 52. Y2. 18. 14. 80. D0. X1. 79. 66. 50.

D0. 3 A Standard Gerber file on its own is not an image description because it does not contain all information the coordinate unit and the definitions of the apertures are not defined in the RS 2. D file. Apertures are the basic shapes, similar to fonts in a PDF file. The coordinate units set manually by the operator of the plotter. They were described in a free format text file, called an aperture file or a wheel file, intended for human reading. It was called a wheel file because the apertures were mounted on a rotating wheel and the operator defined the apertures by selecting a wheel and mounting it on the plotter. There are no standards for wheel files. The designer and the plotter operator had to agree on these case by case. Therefore, standard Gerber is an NC standard but not an image definition standard. Standard Gerber supports only the simple imaging operators that a vector plotter is capable of drawing tracks and flashing apertures. The only way to create large copper pours with a vector plotter is to paint aka stroke or vector fill them with a vast number of tracks. Painting was also used to create all but the simplest pads because of the cost of creating a corresponding physical aperture. Painting results in very large files that take long time to process. It creates the intended image but the original shape of the copper pour or pad and must be laboriously recovered in CAM.
