In Batch Mode item, Separate file per layer should be selected.

Parameters in Aperture Matching Tolerances, both Plus and Minus should be set to be 0.005mil. Parameters in Film Size can be set as default by Altium Designer and error may be caused if these parameters are set to be too small. Little should be done in this tab and Legend symbols don't matter much.īased on the discussion talked about previously in this article, Embedded apertures (RS274X) should be ticked with other items becoming grey and no further actions are required. Mechanical layers to add to all plots can be neglected. Cross can be marked at the end of layers that need to be plotted or mirrored. In this tab, layers to plot and to mirror should be determined. The highest resolution is 2:5 whereas the lowest resolution is 2:3. For Format, three alternatives are supplied.
For Units, either Inches or Millimeters can be selected. Under General button, two parameters should be determined: Units and Format. Then, Gerber Setup dialogue window will come out, in which five items are available for engineers to set corresponding parameters in their Gerber files: General, Layers, Drilling Drawing, Apertures and Advanced. pcb file opened with Altium Designer software, click File>Fabrication Outputs>Gerber Files sequently. In the following part of this article, Gerber files generation methods will be displayed concerning PCB design software.

Furthermore, when it comes to two layers with the same design data, Gerber files should be still generated respectively to avoid possible misunderstanding.ĭifferent PCB design software feature different operation steps of Gerber files generation. Gerber files generally contain design data of conductor layer, soldermask layer and silkscreen layer. Therefore, in order to ensure delivery time and reliability of end products, PCB design engineers should learn to generate Gerber files on their own. If your PCB manufacturer uses different PCB design software, you have to generate Gerber files by yourself, further conversation and confirmation will definitely cause more time and delay the production process accordingly.Įven if PCB manufacturer uses the same PCB design software as you do, you are still advised to generate Gerber files on your own since difference in terms of applied software may also lead to possible errors. You are hardly able to make sure the PCB design software you're using is the same as that is being used by your PCB manufacturer. PCB design engineers should never be too lazy to generate their own Gerber files for the following two reasons. When it comes to PCB assembly, a stencil layer is included in Gerber format and component locations are regulated as well, which will be regarded as significant reference data for SMT (Surface Mount Technology) assembly, thru-hole assembly and mix of them. put it simply, Gerber format files have to be depended from beginning to the end of PCB fabrication process. When it comes to bare board fabrication, Gerber format is called for by both standard photoplotters and other manufacturing equipment desiring image data like legend printers, direct imagers or AOI (Automated/Automatic Optical Inspection) equipment etc. Gerber format file is applied to describe design requirement of each image of a circuit board and it can be applied for both bare board fabrication and PCB assembly. PCB manufacturers won't fully understand all details of a PCB design file unless Gerber format file is contained in it as reference and guidelines. Printed circuit boards are designed in a specialized EDA (Electronic Design Automation) or a CAD (Computer-Aided Design) system that further generate board manufacturing data based on which circuit board fabrications are commenced. Initially developed by a company with the name of Gerber, Gerber format currently refers to a widely accepted standard PCB industry software sticks to, capable of describing circumstances of board images such as conductor layers, soldermask layers, legend layers.
