Criteria for irregular components 6
Definition:
A component is deemed to be irregular when it does not satisfy the conditions for regular compo-
nents. 6
Additional conditions for centering with the component vision system: 6
– In any one row up to 3 different lead types are permitted.
– In any one row up to 15 groups are permitted.

Pitch deviation 6
The pitch deviation (which is the distance from the center of one lead to the center of the next) can
be edited separately for each component in the GF editor. If this value is exceeded during the vi-
sion inspection, the component will not be centered and therefore not placed. 6
Limit values for quality measurement 6
Components exceeding the limit values for quality measurement will be rejected and, therefore,
not placed: 6
– Difference in the number of leads between the original and the model.
– Pitch deviation larger than the value in the GF file.
– Larger orthogonality error than specified in the GF file.
– Larger deviations of the external dimensions.
– Deviation of the central point greater than the permitted positional tolerance for pick-up.
