12.6.19.1 Error Message: LEAD MISSING
1. Cause:
Poor component quality: Laser beam cannot
reach component lead
Analysis:
Chopping Operation Activate vision system:
Do lead ends form a straight line?
Raw data: Count leads
2. Cause:
Handling error: Lead bent laterally
Analysis:
Chopping Operation activate vision system:
Are leads bumping together?

Continuation of Error message: LEAD MISSING
3. Cause:
Erroneous lead description
Analysis:
Lead description J-Iead package form (only gull-wing
permitted).
Lead length described correctly?
(Lead length = contact length incorrect!)
4. Cause:

Continuation of error message: LEAD MISSING
5. Cause:
Calibration error on x/y-plane
Analysis:
Test command 8+3: Does one row of leads in ADP.OUT
exhibit only (-1)-values?
Chopping operation: Activate vision system - Do scan lines
exhibit systematic offset?
6. Cause:
Calibration error with IC-sensor after
calibration of coplanarity option
Analysis:
Test command 8+3: Does a row of leads in ADP.OUT
exhibit only (-1)-values?
