How do i create soldermask?

FAB3000 can extract the Pads from your Top and Bottom metal layers to generate a Mask Layer.


  • Go to menu: Fabrication | Generate Mask Layer(s)...  verify the options (see below), and press OK to create the Mask Layers.


Top Pad Master:  This is the Top metal layer.  Some older PCB designs may have a separate layer with just the Pads (i.e padmaster) - if so select that layer.


Bottom Pad Master:  This is the Bottom metal layer.  Some older PCB designs may have a separate layer with just the Pads (i.e padmaster) - if so select that layer.


Clearance from Pads:  This is the annular ring between Mask and Pad.  Default: 5 mils (0.127mm).


Maximum Pad Size:  Assign the maximum Pad master object dimensions that will be referenced in your generated mask layer(s).  Any Pads with dimensions larger than this value are omitted.   Default: 300 mils (7.62mm).


Pad Selection:  Choose what Pad Master object types will be referenced in your generated mask layer(s).  Default: Flashes Only
