Solder paste stencils

Macaos has developed a powerful and flexible tool for designing solder paste stencils from your PCB data.

Stencil Product Creator

Using the copper layer and paste mask layer data from the PCB, you can do the following:

  • Select a frame from among pre-defined or uploaded frame data
  • Adjust all opening sizes by a percentage of area
  • Adjust the corner rounding of all openings
  • Fine tune individual opening sizes to correct for process issues
  • Mark fiducials for etching (rather than cutting)
  • Add text
  • Place top and bottom openings side by side on the same stencil
  • Split a large opening into an array of smaller openings
  • Define "step" regions of the stencil to be etched down to a different thickness

All opening size adjustments are defined as a percentage of the copper pad area (when copper data is available). The WYSIWYG viewer lets you see how your adjusted openings compare to the copper pads.

A frame manager and editor allows you to upload frames or build new frames based on pre-defined templates. Frames may be defined with variable texts (company name, product number, etc) which automatically get substituted in the Stencil Product Creator.
