ERF Variable |
Description |
v_pitch_tol |
Enables you to define the pitch tolerance for a row of
SMDs. This tolerance is used to look for more pads that can be connected to
the row according to a measured pitch and within the defined pitch tolerance.
This variable enables you to define the pitch tolerance for
a particular row of SMDs. SMDs whose pitch [inter-pad spacing] does not
exceed the pitch (plus tolerance) defined for a particular row can be
included in that defined row. This tolerance also controls the spacing permitted between
two SMD pads along their narrow sides (which is dependent on the row
direction). The maximum allowed spacing is 3*v_pitch_tol
. v_pitch_tol
can have a maximum value of 50 mils. |
