-====== How to make PCB solder paste stencils ======
-You'll need:
-  - A laser cutter
-  - Kapton film, I like the 1 mil thick 1 ft square sheets from [[McMaster-Carr|http://www.mcmaster.com/#2271K2]]
-  - Solder paste such as [[Kester No-Clean|http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=KE1507-ND]]
-Software:
-  - PCB layout software (well, thats how I do it) - this example will use EagleCAD
-  - [[Pentalogix ViewMate Gerber viewer software|http://www.pentalogix.com/Download/download.html#item8]]
-  - [[PDFCreator|http://sourceforge.net/project/showfiles.php?group_id=57796]] or some other free PDF printer
-===== Create Gerber files of cream layer =====
-This is the PCB we'll be making a stencil for. It only has one chip but of course you can use a more complex layout
-{{:laserinfo:eagle.gif|}}
-Your PCB software should be able to create/export the Cream Layer (solder paste layer) in Gerber RS274x format. In Eagle you can make your own Job for this quite easily
-{{:laserinfo:creamjob.gif|}}
-Also export the Dimension layer (PCB outline) since that will help a lot in registration
-===== Import cream Gerber in ViewMate =====
-Start up ViewMate and File->Import->Gerber one of the Gerber files generated
