2Di INSPECTION
2Di SETUP
SETUP TIPS
Problem Solution
No inspection Setup available Ensure that 2Di inspection is enabled in Set Prefs.
System not inspecting or
inspection cycle not being
carried out
The 2D inspect rate may equal 0.
Order of Inspection If a particular sequence of site inspection is required, the sites should be
selected as every cycle sites and setup in the sequence required. Every
cycle sites are inspected in the order that they were setup. General sites
are inspected in an order that depends on their position and their
inspection sequence cannot be set. If at a later date a site is edited the
sequence is affected.
Screen and Board - Cleaning
Before Setup
Before 2Di inspection setup, ensure the screen and board being used
have been thoroughly cleaned and are free of all paste deposits. If either
are not cleaned thoroughly any remaining smearing, partially blocked
apertures or paste on the board may cause an incorrect setup.
Site Area Accuracy Ensure that when setting site parameters (height, width etc.), the site
graphic is placed around the site to give clearance from the apertures
and pads and to prevent other areas being inspected.
Lighting Conditions If the inspection result is not as expected, it is possible that the site was
learnt under different lighting conditions. This problem may be
resolved by re-learning the site under new lighting conditions, or by the
use of paste scaling for paste present adjustment.
Site Quality The sites selected for inspection should be of good quality. Sites should
not have rounded or chamfered edges or uneven or excessive tinning,
this can lead to misleading results when attempting to learn sites.
Sites Being Lost Ensure that both board and screen have been learnt. After adjusting
board or screen site parameters always learn both, further editing can be
done at a later stage. The number of pads must equal the number of
apertures for a successful site.
Inspection alarms too frequent
and unnecessary
This may be a symptom of limits being set too tight. Relax the limits so
that results of an acceptable print produce pass or warning, not alarm, or
use the global limit option or limit options to disable the particular limit
checking.
