![]() PCB Fabrication Data must comply with a number of rules: all layers must be aligned, a profile layer must be included, etc. In industry this is considered poor practice and engineers should use the appropriate X2 attribute instead. Sometimes the file extension is abused to indicate the file function - e.g.BOT for the bottom layer rather than the standard extension. ![]() A simple informal method is to express the file function clearly in the file name. ![]() If attributes are not supported only informal methods are available. FileFunction attribute is the standardized method to link each layer in the PCB with its corresponding Gerber file in the fabrication data. The fabricator loads them into a computer-aided manufacturing (CAM) system to prepare data for each step of the PCB production process. Fabrication data contains a Gerber file for each image layer and drill span (copper layers, solder mask, legend or silk.) (For historic reasons drill data is also transferred in NC formats although Gerber files are often of better quality.) Typically, all these files are " zipped" into a single archive that is sent to the PCB bare board fabrication shop. The CAD systems then outputs PCB fabrication data to allow fabrication of the board. PCBs are designed on a specialized electronic design automation (EDA) or a computer-aided design (CAD) system. gbr though other extensions are also used. Files with attributes are called X2 files those without attributes are X1 files. In 2014, the graphics format was extended with the option to add meta-information to the graphics objects. There are two major generations of Gerber format: 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. 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. This data typically contains a Gerber file for each image layer (copper layers, solder mask, legend or silk.). The CAD systems output PCB fabrication data to allow fabrication of the board. The official website contains the specification, test files, notes and the Reference Gerber Viewer to support users and especially developers of Gerber software. It is the de facto standard used by PCB industry software to describe the printed circuit board images: copper layers, solder mask, legend, drill data, etc. Hopefully this simple step will able to guide you through without spending unnecessary time on non-value added tasks.The Gerber format is an open ASCII vector format for printed circuit board (PCB) designs. ![]() pcb file is stored in \My Documents or sub directories of it, then the error message will prompt up and so it is always advisable to store it in C:\ drive to eliminate any unrecognized special character error that cannot be handled by the utility. An illegal character is included in the file path name”. pcb file should be located without any special character especially the ‘space’ in between any directories that will cause error message of “Opening database file failed. Clicking on it will launch the utility ready for you to browse for specific. Users can look for it under the C:\Program Files\ZUKEN\BD-Viewer folder and you will notice a viewer.exe executable file in the folder. Once download and install the utility, do not be surprised if you can’t locate the utility under your Program Lists. An illegal character is included in the file path name” and so on. pcb format file residing in your local drive by avoiding some common error messages such as “Opening database file failed. The procedure will not cover comprehensive step by step on how to use it but instead, it will just show you the steps on how to load the utility, browse for the correct. If you are first time using Zuken BD Viewer and experiencing difficulty in operating the utility, here is a simple step that will able to guide you through. Zuken BD-Viewer is one of the famous utilities that allows PCB (Printed Circuit board) designer to view board file which is especially common for Japanese board makers.
