Defines how widths of paste
pads are sized: by distance,
factor or value.
Create Solderpaste
Wide Mode
.spo_w_val Float Feature,
Comp.
(-500 to 500; default=5)
When
.spo_w_mode=Distance,
.spo_w_val is the reduction/
expansion expressed in mils
or microns of the paste pad
width relative to the SMD
pad width. For example,
.sp_w_val=5.0 mils shrinks
paste pad by 5.0 mils (2.5
mils on each side) relative to
SMD pad width. Positive
number results in smaller
paste pad, negative number
in larger paste pad. When
.spo_w_mode=Value,
.spo_w_val becomes the
absolute width of the paste
pad (for example, 5.0 mils
becomes the actual width of
the paste pad).

.src_orientation Integer Comp. (-1 to 3; default=-1)

assembly tape, or (for
manually inserted
components) the orientation
in which pin #1 is “in the
