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.

OPTIONS AFTER AN INSPECTION ALARM

The machine stops at the first inspection alarm. When an inspection alarm

occurs, several menu bar options become available.

The functional description for each option is as follows:

Accept Selecting this option clears the alarm panel, changes the beacon back to green

and feeds the board through the machine.

Inspect More Selecting this option clears the alarm panel, changes the beacon back to green

and allows the inspection sequence to continue, until it either completes inspec-

tion or raises another alarm.

Recovery Action Selecting this option displays the following menu:

The user prompt text shows the following lines:

‘Clean Mode 1 : XXXX’

‘Clean Mode 2 : YYYY’

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.

Re-print Board Selecting this option clears the alarm panel and changes the beacon back to

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

the beginning. All the existing alarm information is cleared.

NOTE

The Re-print Board button is not available if the current board has already been

re-printed.

Adjust Selecting this option allows the adjustment of process parameters.

Inspect All Selecting this option clears the alarm panel and changes the beacon back to

green. The inspection sequence is restarted from the beginning. All the existing

alarm information is cleared.

Edit Global Selecting this option opens the edit global parameters window, allowing param-

eters that are used throughout the inspection to be altered.

Edit Limits Selecting this option opens the limit sets window, allowing a set of limit

parameters to be selected and altered.

New Pre-images Selecting this option initiates a pre-print inspection on the next print cycle to

capture the new pre-images. The message ‘New pre-images will be collected

next print cycle’ is displayed.

NOTE

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

Edit Site Selecting this option opens the site parameters window, allowing adjustment of

the site specific parameters.

Inspect Site Selecting this option opens the inspection results window and displays the

following menu:

Selecting Next or Previous moves the highlight up and down the list of site pads.

Selecting Toggle Paste either shows or hides the paste display overlay onto the

monitor. The toggle paste facility on the board image is only functional with the

board inspection type set to advanced. Toggling paste on the screen is only

available on Horizon and Infinity machines and only with the stencil inspect type

set to basic or advanced.

Selecting Auto Scale automatically adjusts the paste scaling value for the

current site, to cause the value of paste present, on the pad currently selected in

the inspection result list, to be reported as 100%. This is used where the site pad

causing the alarm is actually a good print.

Reject Selecting this option clears the alarm panel and the board is fed to the output end

of the rail system and held there.
