FABRICATION array

MATRIX Array Level: 4

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

	Description
JOB=NAME	The name of the Job to process. Required. Dynamic Job References are also supported.
UNITS=VALUE	Units to use for this FABRICATION array only. Choose from: mil mm cm inch um (default: mm)
ETCH_FACTOR=VALUE	Enlarge or reduce objects sizes. Useful for applying etch factors. ETCH_FACTOR=METHOD,VALUE,SET METHOD Assign a method to calculate Etch factors, choose either: absolute or percent Default: Absolute VALUE Absolute method: Assign the offset distance for the etch factor. Default: 0.0 Percent method: Assign the etch pecentage value per side. Default: 100.0 SET Selected Objects. If Empty, both top and bottom metal layers are selected. Example: ETCH_FACTOR=absolute,0.02,[top] ETCH_FACTOR=percent,125,[bottom]
SILKSCREEN_OPTIMIZER=VALUE	Silkscreen optimizer removes the overlapping silkscreen data from soldermask pads. SILKSCREEN_OPTIMIZER=CLEARANCE,MINSIZE,METHOD,SET CLEARANCE Minimum mask spacing from Silkscreen objects. Default: 0.127mm MINSTUB Minimum length for remaining lines after trimming the silkscreen. Default: 0.05mm METHOD Select between two trim silkscreen methods: Trim or Composite Default: Trim SET Selected Objects. If Empty, both top and bottom silkscreen layers are selected. Example: SILKSCREEN_OPTIMIZER=0.005,0.002,[silk] SILKSCREEN_OPTIMIZER=snowman,0,[Bottom_Silk]
TEARDROP=VALUE	Add Teardrops to improve pad/trace connections. TEARDROP=TYPE,OFFSET_FACTOR,SET TYPE Assign a Teardrop type either: teardrop or snowman OFFSET_FACTOR Assign an offset multiple for teardrops construction (not used with Snowman type). Default: 2.0 SET Selected Objects. If Empty, both top and bottom metal layers are selected. Example: TEARDROP=teardrop,2,[top] TEARDROP=snowman,0,[bottom]
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 Panel Coordinates referenced from the center of the PCB; 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 Panel 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 Choose either: YES or NO Default: No Example: add_rout_cutouts=0.1,@bottom,CCW,yes add_rout_cutouts=2.5,@top-2,CW,no

Example FABRICATION Array:
