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.

Where XXXX and YYYY are the descriptions of the clean mode settings, ie

‘WVWD’ for wet, vac, wet, dry.

Paste Load Selecting this option initiates a paste load cycle, if a paste dispenser is fitted or

enables paste to be loaded manually.

Clean Mode 1 and 2 Selecting either clean mode 1 or clean mode 2 initiates the screen clean cycle set

up for that mode.

green. The board is re-printed and the inspection sequence is started again from

the begining. All the existing alarm information is cleared.
