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.
