Upload your gerber files (one for the paste layer and one for the outline), get an STL file.

If you use eagle, you can find a CAM script that will export the right layers here.

If you use Fritzing, select File -> Export -> For Production -> Extended Gerber and select a directory for the resulting files. Upload the file named your_project_contour.gm1 for the outline and your_project_pasteMaskTop.gtp for the paste layer.

This site is untested, unfinished, unpolished and unlikely to work for anything serious. Good luck.

Files

Outline of the board used to create the stencil. To create a stencil of different size, use the options below instead.

Processing Options

Use negative values to increase the space between tightly spaced pads at the cost of making the pads smaller.

Hints

  • If you find the pads and holes don't align properly, try increasing the distance between board and ledge by a few tenths of a millimeter. If that's not it, your printer's calibration might be off.
  • You can use negative values for hole size increase to increase the separation between closely spaced tabs, to allow printing a separating line. The downside is that this makes all pads smaller.
  • Some boards can produce 2-dimensional walls if pads directly touch each other, which can throw of slicers. If this happens, increase the hole size very slightly (like 0.001mm) to make the holes overlap.
  • The thicker the stencil and the smaller the solder pads, the more paste will stick to the stencil. If you're not getting enough paste on the pads, make the holes bigger or reduce the stencil thickness.
  • If you've got a file that's not working right, send it to me at rob@kirberich.uk and I'll have a look to see what's up.


Special thanks to kazade for the brilliant idea of using OpenSCAD to make this work. This app uses pcb-tools to read Gerber files and SolidPython to generate OpenSCAD code. OpenSCAD is used to generate the resulting STL files. The website is built using Django.

You can find the code for the underlying converter at https://github.com/kirberich/gerber_to_scad. The code for the web app can be found at https://github.com/kirberich/gerber_to_scad_service.
