materials, etc. Final assembly inspection must not be overlooked, nor measurement of electrical and
mechanical end components, such as circuit breakers for the automotive industry. In this case,
distances, positions or dimensions can be analyzed and tracked.
3D Reconstructions Using CT
Viscom offers its X8011-II and X8068 systems for these versatile tasks. Electronics manufacturers can
perform both manual and automated inspection processes with these X-ray systems. The X-ray
machines can be used as an offline solution. Inspection results from manual mode are stored using
the live tools. Availability of automatic X-ray analysis and manual or semi-automatic inspection
means that the X8011-II PCB and X8068 offer operators a high degree of flexibility. Viscom software
is specially developed for SMT production enabling fully automatic analysis as well as intuitive,
comprehensive analysis function, which helps the operator to check inspection objects easily and
precisely. 3D reconstruction is also possible with Viscom’s proprietary XVR computer tomography
(CT). This means defects can be detected, volumes reconstructed, and structures measured in real
units of measurement. Thereby individual layered or sectional images can be created. The optional
CT method is used in particular for prototype evaluation, reverse engineering and series production.
From manual inspection of individual components and assemblies through fully automatic inspection
of large and heavy printed circuit boards with a diameter of 722 mm (28.4") and a weight of up to 15
kg (33 lbs), Viscom’s X8068 system covers the entire inspection portfolio for electronics production.
Excellent image results are particularly important here. This is made possible using open microfocus
transmission tubes. Viscom develops and manufactures these in its own modern X-ray competence
center.
High-resolution digital flat panel detectors are used for the highest magnifications and optimum
image quality for evaluation of X-ray images. The modular Viscom system concept offers practically
every individual user optimum inspection possibilities. The X8011-II PCB system by Viscom provides
flexible exchangeable modules to inspect a wide variety of inspection objects. In addition to an
object stage, Viscom offers a 360° rotation module and a motorized rotation and tilt axis. These tools
enable the inspection object to be placed in various angular positions to gain a better insight into
areas to be tested. The individual modules can be easily exchanged during operation and are pre-
calibrated, which eliminates the need for time-consuming calibration after the exchange. The
detector can be tilted up to 60 degrees.
Test Results are Comprehensively Documented
Documentation of the results is just as important
as the actual inspection, especially if the
inspection is undertaken as part of the
investigation of a field return. The aim should be
to quickly and automatically generate test
reports for the customer in a format that
presents the results to the customer quickly and
easily. The test reports should also be easy to
compare. This is particularly important in the
development or prototyping phase, where
inspections check individual development steps
and influence subsequent implementations.
Standardized reports are helpful when it comes
to understanding results and the easy
interpretation of new development steps.
Viscom offers ReportCreator for fast and easy
creation of these inspection reports. The
operator defines the report settings, i.e. the
display of inspection results, and saves them as a
reusable template for their customers. Customer
information such as logos and addresses can also
be stored in addition to the test results.
The reports can consist of a cover sheet, the table of contents, overview screens with result markers,
summaries of the test results in table form, and a detailed presentation of the results with analysis
steps, image acquisition parameters and comments. The actual test results can be filtered by manual
or automatic, good or bad results. Each inspection object can also be assigned to individual test items
using barcodes or DMC. This means detailed documentation can be created for sampling and for field
returns describing in detail the current status to the customer. ReportCreator’s intuitive menu
navigation is also helpful for creating reports, enabling the person responsible to generate reports
quickly and easily on behalf of the customer.
A very valuable part of the report is the information about the radiation exposure of each individual
region of the tested assembly. This information assures the user that even sensitive components
have been tested within the maximum permissible radiation. In addition, the MXI systems from
Viscom are intelligently designed so that inspection does not continue once a preset limit value is
reached.
Conclusion
A wide inspection spectrum combined with a simple report generation means that the X8011-II PCB
and X8068 inspection systems are ideally suited for medium-sized companies with versatile
inspection tasks. The machines are a result of years of experience on the part of Viscom’s
development department, both systems provide a stable, long-lasting machine design and intuitive
operation, to fullfill the potential customer’s multifunctiona tasks.
