OMRON Launches PCB Inspection System "VT-S10 Series"
KYOTO, Japan, Aug. 2, 2021 /Kyodo JBN-AsiaNet/ --

- Industry-first Imaging Technique and AI Achieve Reductions in Skill 
Requirements for High-precision Inspection - 

OMRON Corporation based in Kyoto, Japan, announced on August 2 that it will 
globally launch on August 5 the PCB inspection system "VT-S10 Series," which 
features an industry-first (*1) imaging technique and AI to automate the 
high-precision inspection process for electronic substrates, thus eliminating 
the need for specialist skills. As the inspection of in-vehicle electronic 
substrates becomes increasingly difficult with the growing need for the 
fifth-generation mobile communication system (5G), electric vehicles (EVs), and 
autonomous driving, this new offering from OMRON performs high-precision 
inspection of such key components to maintain and enhance their quality, thus 
contributing to the security and safety of society.

In recent years, demand for electronic substrates for 5G, EVs, and autonomous 
driving has grown rapidly, which in turn is raising the quality requirements of 
substrates since these applications involve risks to human lives. As substrates 
become more dense and miniaturized, inspection becomes more challenging, with 
the result that conventional PCB inspection systems struggle to take an 
accurate image of solder shapes, which limits the scope and parameters of 
inspection. Meanwhile, on production floors, amid the growing shortage of 
skilled workforce and humanpower in general, workers are required to avoid 
congestion and close contact and to limit their movement as they work to 
prevent the spread of COVID-19. It has thus become urgent to reduce the 
frequency of visual inspections and lower the experience and skill requirements 
for setting and starting up automated inspection equipment, in addition to 
advancing inspection accuracy.

Equipped with OMRON's proprietary MDMC (Multi-Direction Multi-Color) imaging 
technique, the VT-S10 Series automatically optimizes irradiation angles, 
colors, and light intensity of illumination during inspection of substrates 
according to characteristics such as the shapes of electronic components and 
soldering on the substrates, thus reducing the human-hours required for setup 
by approximately 70%. (*2) Furthermore, with the assistance of AI that has been 
taught the imaging knowhow OMRON has accumulated over more than 30 years in the 
field of automated inspection, as well as knowledge in solder inspection, this 
PCB inspection system is capable of automating inspections that have hitherto 
had to rely on human senses, significantly improving inspection accuracy.

Under the banner of the strategic concept "innovative-Automation," which 
consists of the "three i's," namely, "integrated (evolution in control)," 
"intelligent (intelligence developed through ICT)," and "interactive (new 
harmonization between humans and machines)," OMRON is driving innovations on 
the production floor. Through the integration of the widest range of control 
devices and the use of AI fully versed in solder inspection, the VT-S10 Series 
is the latest offering from OMRON that embodies the "innovative-Automation" 
concept. Going forward, OMRON will continue evolving production floors hand in 
hand with customers. By expanding the scope and parameters for automated 
inspection, OMRON hopes to free operators from simple, monotonous work so that 
they can engage in more creative work, which it believes ultimately contributes 
to the security and safety of society.

     compared

Key Features
1. MDMC imaging technique significantly lowers chances of erroneous decisions:
By utilizing OMRON's proprietary MDMC illumination, the company has developed 
an imaging technique for high-precision inspection of ever-advancing substrates 
and components. Through the flexible manipulation of irradiation angles, 
colors, and light intensity, it has become possible to capture solder shapes 
more accurately than conventional imaging methods, eliminate the interference 
of shadows of neighboring tall components, and distinctly read patterns on 
substrates and prints on the surface of components.

(1) 3D imaging from all angles for accurate inspection of complicated solder 
shapes

(2) Accentuated white lighting eliminates the influence of illegible printing 
to achieve accurate character inspection

2. Minimizing programming human-hours by quantitative inspection and 
AI-assisted qualitative inspection:
Based on the knowledge that the company has accumulated in solder shape 
inspection, as well as images gained through MDMC illumination, OMRON has 
developed AI dedicated to solder inspection. The company combined this 
AI-assisted inspection with quantitative inspection by MDMC to achieve 
reductions in both the required level of teaching skills and the chances of 
erroneous decisions. In a validation test with a customer, OMRON verified a 
reduction in visual inspection human-hours by 85%.

3. M2M system for production of defect-free products:
Linking data with production equipment from other manufacturers allows for 
monitoring quality trends, which prevents defects from occurring.

(1) Visualizing quality by developing a database of inspection results, 
including measurement values and images, from each process

(2) Improving the first pass yield rate by automatically optimizing 
post-print/post-placement inspection criteria based on the inspection results 
in the final process

(3) Linking data with other production equipment manufacturers to reduce and 
prevent defects
A validation test with a customer showed that, with the introduction of this 
M2M system, the defect ratio was reduced by more than 50% by detecting and 
dealing with quality variations before defects occurred.
