Exporting Stencil to DXF for Manufacture

    I can't see any free options, but there are free PDF to DXF converters, maybe you can do it this way?

    Also I'm curious about the need to do this, I thought stencil manufacturers accept Gerber files? Unless you want to do it yourself, laser cut on the polyimide?

    Hey Jayx,

    Ah good idea I wlll try this. 

    Yes, we have a laser cutter in the workshop and I have bought some mylar sheets. The technician wants a DXF to use it!

    DesignSpark Mechanical will import PCB files and output dxf files.

    This may be a good solution

    I did install DS Mechanical but the process seemed a bit involved. I couldn't just import the one layer I wanted (only .idb) files which then created a 3D model. How I then get the DXF I want - I have no idea. Do you have any links that might help?

    Apparently Mylar is not the best, polyimide (Kapton) works better according to this study: https://www.smtnet.com/library/files/upload/plastic-vs-metal-stencils.pdf 

    "Mylar is also being marketed as a stencil material. This material is not well-suited for stencil printing because during stencil cuts this material creates “ridges” around the apertures thereby reducing the co-planarity between the stencil and the PCB leading to smearing."
