The FABRICATION array allows anyone to perform PCB manufacturing commands such as Etch Compensation (Grow/Shrink), TearDrops, Trim Silkscreen, etc.
Fields in the FABRICATION array

| REMOVE_OUTSIDEBORDER=VALUE | Remove objects Outside PCB Border like notes, drawing objects, etc. Perfect for creating 1UP PCB jobs that are ready for panelization and manufacturing.
REMOVE_OUTSIDEBORDER=TRIM_PAD,TRIM_TEXT,TRIM_TRACE,CLEARANCE,LAYERS
TRIM_PAD=<YES|NO> Pads extending past the border will be trimmed. Drill holes will be ignored. Default: YES
TRIM_TEXT=<YES|NO> If Checked, Text extending past the border will be trimmed. Default: YES
TRIM_TRACE=<YES|NO> If Checked, Traces extending past the border are trimmed. If unchecked, Traces are trimmed as Polygons. Default: YES
CLEARANCE=NUM Trim all objects by this Clearance from the PCB border edge. Default: 0.0
LAYERS Enter Layer names (Comma separated) or Dynamic Layer Types. Wildcards are permitted. Default: [All PCB] (i.e All PCB Layers).
Example:
REMOVE_OUTSIDEBORDER=yes,yes,yes,0,[all]
REMOVE_OUTSIDEBORDER=yes,yes,yes,0.02,[All PCB]
- Note
- SHORTCUT: If REMOVE_OUTSIDEBORDER= is empty, these defaults are used: REMOVE_OUTSIDEBORDER=yes,yes,yes,0,[All PCB]
|
| DELETE_LAYERS=VALUE | Enter Layer names (Comma separated) or Dynamic Layer Types. Wildcards are permitted.
DELETE_LAYERS=PERMANENT,LAYERS
PERMANENT=<YES|NO> If no, only the objects on the layer will be deleted; the layer still remains in the database.
If Yes, delete layer objects plus layer from database. Default: YES
LAYERS Enter Layer names (Comma separated) or Dynamic Layer Types. Wildcards are permitted. Default: [Empty] (i.e All Empty Layers).
Example:
DELETE_LAYERS=yes,[empty]
<-— Deletes all empty layers from database. REMOVE_OUTSIDEBORDER=no,[top]
<-— Removes objects from layer top, layers remains in database.
|
ADD_ROUT_PROFILE=VALUE
|
The rout profile is used to cut out the PCB from within a panel. Typically PCB's using Routs are held in the panel using Tabs.
ADD_ROUT_PROFILE=TOOL_DIAMETER,PLACEMENT,DIRECTION,PLUNGE,RETRACT
TOOL_DIAMETER The rout path tool width
PLACEMENT Tab placement using Relative Coordinates referenced from the center of the JOB or PANEL; or 0-360 degrees.
DIRECTION Either CW (for Clockwise) or CCW (for Counter-Clockwise). Default: CW
PLUNGE The distance extending plunge point. Default: 0
RETRACT The distance extending past the Ending Distance. Default: 0
Example:
add_rout_profile=0.1,@right,CW,0,0
add_rout_profile=2.5,45,CCW,2.0,2.0
|
ADD_ROUT_CUTOUTS=VALUE
|
The rout cutouts are used to remove the internal openings in a PCB.
ADD_ROUT_CUTOUTS=TOOL_DIAMETER,PLACEMENT,DIRECTION,CLEANUP
TOOL_DIAMETER The rout path tool width
PLACEMENT Tab placement using Relative Coordinates referenced from the center of the cutout; or 0-360 degrees.
DIRECTION Either CW (for Clockwise) or CCW (for Counter-Clockwise). Default: CCW
CLEANUP_CUT Extend the Retract a little further to prevent rough edges. Choose either: YES or NO Default: No
PLUNGE_CENTER Add the Plunge point in the center of the cutout. Choose either: YES or NO Default: No
Example:
add_rout_cutouts=0.1,@bottom,CCW,yes,yes
add_rout_cutouts=2.5,@top-2,CW,no,no
|
| ADD_TAB=VALUE |
Rout tabs are used to hold each PCB in place on a production panel, during the Manufacturing and Assembly processes. Afterwards, finsihed PCB's can be snapped out of the Panel.
ADD_TAB=WIDTH,PLACEMENT
WIDTH The tab width size
PLACEMENT Tab placement using Relative Coordinates referenced from the center of the PCB; or 0-360 degrees; or Add Vertex #
Example:
add_tab=0.1,@top
add_tab=0.1,@bottom
add_tab=2.5,45
|
| ADD_TAB_PERFORATED=VALUE |
Rout tabs are used to hold each PCB in place on a production panel, during the Manufacturing and Assembly processes. Afterwards, finsihed PCB's can be snapped out of the Panel.
ADD_TAB_PERFORATED=TYPE,PLACEMENT,PERFORATION
TYPE Chose the perforation type either: SINGLE or DOUBLE
PLACEMENT Tab placement using Relative Coordinates referenced from the center of the PCB; or 0-360 degrees.
PERFORATION=HOLE_COUNT,DIAMETER,SPACING,OFFSET
Example:
add_tab_perforated=single,@bottom,3,0.025,0.025,0.007

| ADD_TAB_ANGLED=VALUE |
Rout tabs are used to hold each PCB in place on a production panel, during the Manufacturing and Assembly processes. Afterwards, finsihed PCB's can be snapped out of the Panel.
ADD_TAB_ANGLED=WIDTH,PLACEMENT,EXIT_ENTRY_ANGLE,TAB_LENGTH
WIDTH The tab width size
PLACEMENT Tab placement using Relative Coordinates referenced from the center of the PCB; or 0-360 degrees.
EXIT_ENTRY_ANGLE The acute angle between the angled tabs exit and entry options. Default: 125 TAB_LENGTH The length of the angled tab.
Example:
add_tab_angled=0.1,@bottom,125.0,0.05
|
| ADD_TAB_ANGLED_PERFORATED=VALUE |
Rout tabs are used to hold each PCB in place on a production panel, during the Manufacturing and Assembly processes. Afterwards, finsihed PCB's can be snapped out of the Panel.
ADD_TAB_ANGLED_PERFORATED=PLACEMENT,EXIT_ENTRY_ANGLE,TAB_LENGTH,PERFORATION
PLACEMENT Tab placement using Relative Coordinates referenced from the center of the PCB; or 0-360 degrees.
EXIT_ENTRY_ANGLE The acute angle between the angled tabs exit and entry options. Default: 125 TAB_LENGTH The length of the angled tab.
