<Length Max> column
Input the maximum allowable lead length.
Input value = Lead Length + Allowable Error
<Length Min> column
Input the minimum allowable lead length.
Input value = Lead Length - Allowable Error
<Pitch Type> column
Set the lead pitch, which is the length from the center of the lead to the center of
the adjacent lead. Since this parameter is sensitive to part recognition, draw the
outline of the part in the SMVision window when registering a part and input the
pitch so that the shape of an actual part matches the outline of the part.
<Pitch Max> column
Input the maximum allowable lead pitch
Input value = Lead Pitch - Allowable Error
<Pitch Min> column
Input the minimum allowable lead pitch.
Input value = Lead Pitch + Allowable Error
<Foot Type> column
Set the length of the lead that touches the surface.
<Foot Max> column
Input the maximum allowable foot length.
Input value = Foot Length + Allowable Error
<Foot Min> column
Input the minimum allowable foot length.
Input value = Foot Length - Allowable Error
<Tolerance Tan> column
Set the allowable tolerance when the lead is bent to the side. Set it as a percentage
of <Lead Pitch>
<Tolerance Rad> column
Set the allowable tolerance for lead length. Set it as a percentage of <Lead
Length>.
<Lead Shape> column
Select the lead shape.
<NORMAL>
Selected when recognizing the general lead shape.

Memo Set the lead group so that the pitch between the lead groups is greater
than the pitch between leads.

7.1.4.2. Lead Group
Set the lead group for User IC. Up to 16 lead groups can be set.
Figure7.26 Screen showing “Lead Group” setting in the dialog box for “User IC Lead Parameter
& Group”
<Lead Group> group
Set the lead group.
<Group No.> column
Displays the lead group number. Applicable range is 0 –15.
<Group L. Num> column
Set the number of leads the lead group has.
<Group P. No.> column
Set the lead parameter number referenced by the lead group. Applicable range is 0
–7.
<Group Angle> column
Set on which side of the component the lead group exists. 0, 90, 180, and 270 in
the above figure denotes the angles.
<Center Tan> column
Set the distance from the component origin point (component center in general) to
the center of the lead group along the tangential line.
<Center Rad> column
Set the distance from the component origin point (component center in general) to
the center of the lead group along the tangential line.
