Chapter 5 Solutions for Errors 5-
23
Lead pitch is too
small. (Up)
An error may be caused when two leads
are closer than the specified tolerance.
Where normal leads are treated as an
error, increase the lead tolerance in the
component DB and check again.
Lead pitch is too
large. (Up)
An error may be caused when two leads
are further apart than the specified
tolerance. Where normal leads are
treated as an error, increase the lead
tolerance in the component DB and
check again.
Lead width is too
narrow. (Up)
Check the component DB and width of
component leads.
Lead with is too
wide. (Up)
Check the component DB and width of
component leads.
Lead tip goes inward.
(Up)
Check the tip of component leads.
Lead tip goes
outward. (Up)
Check the tip of component leads.
Leads are out of the
inspection area. (Up)
Check the offset from the center of
component and adjust the picking
position.
X pitch is smaller
than the value
defined in the DB.
An error may be caused when two leads
are closer than the specified tolerance.
Where normal leads are treated as an
error, increase the lead tolerance in the
component DB and check again.
X pitch is larger than
the value defined in
the DB.
An error may be caused when two leads
are separated by more than the specified
tolerance. Where normal leads are treated
as an error, increase the lead tolerance in
the component DB and check again.
Y pitch is smaller
than the value
defined in the DB.
An error may be caused when two leads
are closer than the specified tolerance.
Where normal leads are treated as an error,
increase the lead tolerance in the
component DB and check again.
Y pitch is larger than
the value defined in
the DB.
An error may be caused when two leads
are separated by more than the specified
tolerance. Where normal leads are treated
as an error, increase the lead tolerance in
the component DB and check again.
This error occurs when balls were not
detected in BGA inspection. Check that the
BGA component is properly entered in the
DB and that the ball status of the
component is normal. If normal, adjust the
illumination and retry inspection.
