CAD or Data Requirements
Multiple CAD tools and custom file converters enable PCB laser programming from customer-provided data. Most laser drilling, routing, and skiving applications can be generated by DXF, DWG, Gerbers, and Excellon drill file formats. In most cases, non-scaled data is required as MLT will make the appropriate scaling or offsets to meet part dimensions.
If concerned about compatibility of your data format or CAD/CAM tool, please contact MLT Sales for more information. For more CAM/CAD guidelines and detailed requirements, click CAD Requirements.
