Inspection & cleaning equipment
Low pressure washer
AB Networks’ low-pressure washer is an eco-friendly cleaning system that delivers dry ice or sodium bicarbonate (baking soda) at pressures of 2 bar or less, while achieving cleaning performance equal to or better than conventional high-pressure washers that typically operate at 100–120 bar.
Issues with conventional high-pressure cleaning methods
-
Risk of damaging the surface of the item being cleaned.
-
Risk of short circuits when used on precision electronic circuits.
-
High-pressure spray can cause debris and cleaning media to scatter, posing safety risks to operators and contaminating the surrounding environment.
The low-pressure washer cleans items thoroughly without the drawbacks of high-pressure methods. It can be applied across a wide range of industries, including semiconductors, electrical and electronic components, mechanical parts, molds and dies, automotive engine components, and food processing.

Ultra-fine particle removal system
The ultra-fine particle removal system is a fine-particle (down to 50 nm) detection and removal solution based on AI vision and high-precision optical and sensor fusion. By combining real-time high-resolution detection, micro-motion control, and customized removal solutions, it is optimized for cleanrooms and semiconductor manufacturing environments.
For sensitive processes where dry ice, pure water, or cleaning solutions cannot be used, it physically removes sub-micron particles using a gel stick.
Applications
-
Used for real-time inspection and removal of contaminants generated in semiconductor and substrate manufacturing lines
-
Applicable to any manufacturing process where micro-defect and particle control is critical, including secondary batteries, precision electronic components, and advanced medical parts production
Differences from conventional cleaning methods
-
Achieves both precision and productivity in particle detection and removal through real-time AI analysis and multi-sensor fusion
-
Unlike conventional chemical- or physical-based equipment (cleaning, X-ray), it immediately tracks the location after detection and separates and removes particles using the optimal method
The ultra-fine particle removal system provides flexible solutions tailored to the customer’s process conditions.

Shadows on challenging curved lenses
-
Complex shape: Lenses have curved surfaces and strongly reflect light, making accurate contamination inspection difficult.
-
Limited access: The edges (outer perimeter) are deeply recessed, creating areas that conventional cleaning equipment cannot physically reach.
-
Risk of damage: Extremely sensitive optical coatings can be damaged even by slight physical contact, making the cleaning process itself an additional risk factor.
-
Critical impact: Even a single micro-particle on the lens surface can critically affect the optical performance of the final product.
Overcoming the limitations of curved lenses
An optimized vision technology that adapts to varying lens geometries and depths quantifies particle positions and links with the cleaning equipment.
3D contour mapping technology
The lens’s complex curved surface geometry is fully digitized in 3D space, and an optimal safe path is designed so that the needle does not contact the lens surface.
Precision access
It safely accesses even deep outer edges without collision risk and removes all hidden contaminants.
Beyond simple inspection: intelligent quality analysis with z-axis indexing
Optimized vision technology that adapts to varying lens geometries and depths quantifies particle positions and links with the cleaning equipment.
Decision support
It supports accurate go/no-go decisions based on data, reducing time and cost.
