This can be useful, but can also lead to confusion, as there can be a significant number of additional files. If you do not specify a target directory in the << Normal - part of the dialogue, TARGET creates the XGerber data directly to your project directory. Attention, the system does not double check for identical names. In the TARGET button you can give individual instructions for the file name for each type of file. This setting is therefore linked to your computer, not to the loaded project.Įxisting users who may be relying on the old familiar settings will also have no problems, as the old settings for new installations will restore as well. This means that if you output XGerber and use the standard file extensions, these will also be used in future projects. The settings of the "Standard" button are preset since V 19.7.0.46. An internationally frequently used nomenclature is given by the button "Standard", results see left (example). For some manufacturers, all files should end in *.GBR. The naming of Gerber and Drill files is unfortunately not standardised.
Gerber X2 information, Gerber X3 informationĪdditional comments regarding the function of the Gerber file will be inserted into the Gerber file itself. at 0,15 mm then use in your projects minimally 0,16 mm so you are on the secure side. If your PCB house manufactures tracks and spacings e.g. Error the number of chords can be increased and so the maximum error be limited when creating arcs in Gerber. Those chords inevitably are too close to the center of the circle in their middle and too far from the center at their ends. TARGET 3001! creates a warning message after conversion because the widening of tracks may lead to spacing violations.Ĭircles and spline curves are created by many short straight pieces. Thinner tracks in the layout now get exchanged by thicker ones. Without additional cost normally 0,15 mm or 6 mil. The smallest Aperture defines, how thin tracks can be processed by the manufacturer. Being exposed means "copper remains" at this point. So "aperture" means the admission width of a lightpen being manouvered over a light sensitive plate. Remember that the Gerber format had been developed for the control of a light sensitive process.
