Summary
The solder mask expansion distance for arcs, fills, regions and tracks can be determined either by relevant Solder Mask Expansion design rules, or manually, by defining an expansion value as part of the object's properties. Alternatively, no masking can be employed for these objects. These three modes are determined by the object's Solder Mask Expansion Mode property. This function returns arc, fill, region and track objects whose Solder Mask Expansion Mode property complies with the Query.
Syntax
SolderMaskExpansionMode : ExpansionMode_String
ExpansionMode_String must be one of the following strings:
'None''From Rule''Manual'
Example Usage
SolderMaskExpansionMode = 'Manual'
Returns all arc, fill, region and track objects whose Solder Mask Expansion Mode property is set to Manual, as well as pad and via objects whose Solder Mask Override property is enabled.
SolderMaskExpansionMode = 'From Rule'
Returns all arc, fill, region and track objects whose Solder Mask Expansion Mode property is set to From Rule, as well as pad and via objects whose Solder Mask Override property is disabled.
SolderMaskExpansionMode = 'None'
Returns all objects except pad and via objects, and arc, fill, region and track objects whose Solder Mask Expansion Mode property is set to either From Rule, or Manual.
SolderMaskExpansionMode <> 'Manual'
Not (SolderMaskExpansionMode
Returns all objects except arc, fill, region and track objects whose Solder Mask Expansion Mode property is set to Manual, and pad and via objects whose Solder Mask Override property is enabled.
SolderMaskExpansionMode <> 'From Rule'
Not (SolderMaskExpansionModeFrom Rule')
Returns all objects except arc, fill, region and track objects whose Solder Mask Expansion Mode property is set to From Rule, and pad and via objects whose Solder Mask Override property is disabled.
SolderMaskExpansionMode <> 'None'
Not (SolderMaskExpansionModeNone')
Returns all pad and via objects, as well as arc, fill, region and track objects whose Solder Mask Expansion Mode property is set to either From Rule, or Manual.
Tips
- The Solder Mask Expansion Mode property is only defined for arc, fill, region, and track objects.
- The single quote characters (') at the start and end of
ExpansionMode_Stringare mandatory.
