• Limit Sets

• Site Parameters

NOTE

The site coordinate parameters are not available whilst a print cycle is in

progress.

To access the parameter adjustment menu during a print cycle select Adjust

Inspect.

The following window is displayed:

The New Pre-images button is only available if Pre-image is set to 1.

SETUP TIPS

Setup Problem Guide

No inspection setup available Ensure that 2D inspection is enabled in Set Prefs.

System not inspecting or inspection

cycle not being carried out

The 2D option may be disabled or 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.

Stencil and Board - Cleaning Before

Setup

Before 2D inspection setup, ensure the stencil 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 thus

preventing 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 stencil have been learnt.

After adjusting board or stencil 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.
