PCB visual inspection equipment (AOI)
What you can do
By introducing and automating the process of extremely small components that are difficult to distinguish through visual inspection, polarity inspection, character inspection, solder inspection, etc., by introducing a PCB visual inspection system (AOI), it is possible to reduce oversights that occur during visual inspection and achieve traceability management of inspection results. Furthermore, the labor shortage due to the aging population is becoming a serious management issue. With product quality assurance now a priority, introducing an automated visual inspection system can solve a variety of issues.
For users who have already installed PCB visual inspection equipment, when replacing equipment or PCs due to aging, the software is designed to maintain the existing operability, allowing for a smooth transition. Of course, even first-time users can easily get started right away thanks to the simple operability.
Also, when adding a visual inspection device to your SMT line, introducing an in-line AOI for component inspection before reflow will lead to early detection of defects and increase your first-pass rate. Please consider taking advantage of the latest functions that continue to evolve.

Benefits of introducing visual inspection equipment
- Quantitative testing can be carried out quickly, contributing to shorter work efficiency
- Preventing defective products from being shipped out through visual inspection
- Establishing traceability and improving quality through analysis of inspection results
- Improving productivity through labor savings
Automated visual inspection equipment can detect minute defects that are easily overlooked by human visual inspection, enabling the early removal of defective products.
This is expected to improve the reliability of the entire production process and also make it possible to maintain quality.
This equipment enhances quality control in board mounting and significantly improves production efficiency.
Lighting types and their features
DL lighting
White lighting is used for component inspection, such as for missing parts, character inspection, and color discrimination of color codes.
The side red lighting can be used for IC character inspection and solder fillet inspection, while the coaxial incident lighting can be used for marker recognition, white component inspection, and scratch and dent inspection, making this lighting suitable for a variety of appearance inspections.
Major features
Part presence/misalignment
Polarity Inspection
Character inspection
Foreign body inspection
SMT solder inspection
IC Bridge
Solder ball
Barcode scan
Screw presence
Tray missing
Laser-printed text
dents
chipped
Scratches
ML lighting
The RGB 3-level lighting makes it easy to distinguish the fillet shape.
In the case of inspection after reflow or DIP soldering, the fillet slope is always colored and captured, making it ideal for solder inspection.In addition, the camera is equipped with coaxial drop lighting, making it applicable to various inspections other than fillets.
Major features
DIP solder inspection
DIP Bridge
Presence of PIN
Solderless
Solder ball
white lighting
Combining it with a macro lens allows for inspection with a wide field of view.
Ideal for simple inspections such as parts inspection, character inspection, and color differences.
Major features
Wrong part
LED lighting
Character inspection
UV lighting
This lighting is specialized for inspecting moisture-proof coatings containing fluorescent agents.
White lighting is possible for component inspection, marker recognition, and barcode reading.
UV lighting can be used for coating inspection.
Major features
Coating presence/absence
Prohibited area scattering

Features of Marantz Electronics' visual inspection equipment
By automating all inspection items, including 3D inspection, eight angle cameras capable of capturing images from oblique angles, laser-based height detection, and Z-axis drive for inspecting tall parts, high-precision inspection is possible.
It continues to evolve every day as feedback and improvements are continuously received while it is actually used at the Marantz Group's mounting factories.
Language support is available in Japanese, English, Chinese, Korean, German, and Spanish, and the service is used in over 50 countries and regions around the world.
The transport system, including the loader, unloader, and intermediate conveyor, can contribute to shortening the time required for changeovers by automatically adjusting the width in conjunction with the inspection machine.
All inspection result images, including pass/fail/false reports, can be saved. Inspection results can be compiled in various patterns, and graphed, saved in CSV format, and all images can be saved at once.
How to choose an appearance inspection device
The size of the equipment is also determined by whether the target workpiece is medium or large.The optimal lighting can then be selected to suit the object being inspected.
We can accommodate a variety of operations and offer a wide range of options, so please feel free to request information or contact us.
