+}}== This page contains Information on how to make a STENCIL for SMD paste ==
-</pre>
+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
+* Disable ALL layers but Layer 31 (tCream)
+** Doubleclick on Layer 31 (tCream)
+** Change Fillstyle to empty
+* 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)
+* Scale factor: 1
+Import the .pdf into Corel draw and you are good to go.
+===Alternative Steps===
+# Enable the dimension
+# Import the PDF to Inkscape
+# Disable strokes for all pads!
+# Save as SVG
+# Import to CorelDraw
+# Make sure the dimension fits
+# Cut!
+== Ze actual cutting ==
+Use Overheadfoil that can be used with a  copier (than its not PVC) i got splendid results using [http://www.amazon.co.uk/NOBO-Transparency-Plain-Copier-sheets/dp/B000WL1WQI  OHP Transparency film from NOBO]
+You find this in my box in the WEL shelfes on the very right, next to the whiteboard. USe freely for stencils (but nothing else)
+'''Place the overheadfoil on a piece of plain white copier paper and cut the stencil with an outline around the PCB'''
+Once you cut it you can remove the overheadfoil from the paper and all the little squers will stick to the paper.
-ho
+'''Cutter settings'''
+* Speed: 100 %
+* Power: 10 %
+* Hertz:  Vollgas.
