Close-up of single inspection defects

Several AOI/AXI systems can be linked to one verification station, or

vice versa: analysis results from one AOI/AXI system can be distrib-

uted to several verification stations. Thus, this Viscom module at-

tains the greatest deployment flexibility while maintaining

simple operability.

A further option is cascading inspection results to both an inline

verification station and a downstream repair station. In this configu-

ration, inspection results are validated and defects requiring repair

transferred to the repair station.

To ease defect assessment and prevent faulty classification due to hu-

man error, the system furnishes additional reference images taken

from an angled view. This unique feature permits all defect images to be

readily classified with the assistance of comprehensive image material.

SPC Software

Wide range of filter functions for

statistical evaluations

The SPC software is employed where processes have

to be controlled by means of short regulating

loops. The software continuously accepts the inspec-

tion data which has been processed by the Viscom

inspection systems and displays deviation ten-

dencies in paste print, chip placement, solder-

ing or bonding. It is thus possible to detect

changes in the manufacturing process in

good time.

This is presented in the form of configu-

rable diagrams which can be accessed

by the SPC server from different locations

via the network. In addition to this, it is

possible to define the process inter-

vention thresholds, so that the process

is interrupted if a specific defect rate is

exceeded. All analyses can be output as

either event-oriented or characteristic-ori-

ented and displayed with the help of a vari-

ety of diagram types. In addition, there is a

very interesting feature: the placement ma-

chine data of each defective component

can also be filed when needed.

Viscom SPC software is fully network-

capable, i.e. data may be analysed and

exported by any number of machines. It is

barcode-controlled and regulates all data re-

quired for evaluation. The SPC software permits

access to specific data, such as that assigned to

a certain dispenser or a particularly critical type

of component. Operation is simple and the soft-

ware is compatible with all Viscom AOI/AXI systems.

It brings a new concept for defect definition. The ad-

vantages of these features are particularly the avoi-

dance of series defects and the documentation of

process results.
