This page contains Information on how to make a STENCIL for SMD paste

This Information is valid for all the electronic CAD programs but I will document how to do it in eagle.

  • Open Eagle
  • Open you .brd file
  • Go to Layers Menu
    • Doubleclick on Layer 31 (tCream)
    • Change Fillstyle to empty
    • Scale factor: 1


  • Menu ->
    • Tools ->
      • DRC ->
        • Masks ->
          • For the CREAM insert MIN: 0 Percent: 90% Max: 4mil
  • Click Apply


Now your tCream (31) Layer contains squares/masks that are smaller than the actual pads. GOOD.

We will export this one layer as PDF now.

  • Print
  • Print to file (PDF)


Import the .pdf into Corel draw and you are good to go.

Ze actual cutting
