AOI Optical and X-Ray Inspection for Reliable Soldering Quality
Consistent and documented inspection is a fundamental element of high-quality electronics manufacturing. At ElektroMont, every assembled PCB undergoes automated optical inspection and, when required, X-ray inspection to ensure that solder joints fully comply with technical specifications.
This multi-stage inspection system ensures that surface-mounted components are assembled correctly, significantly reducing the risk of later failures and ensuring stable product quality.
3D AOI
Automated Optical Inspection
All assembled printed circuit boards are inspected using 3D camera-based automated optical inspection systems. The Mirtec MV-3 OMNI 3D camera AOI systems used in our production environment are capable of detecting manufacturing deviations with a very high level of accuracy.
During the inspection process, the system verifies the presence and precise placement of components, the correctness of polarity, the amount of solder material, and the integrity of solder joints. It also identifies solder bridges, insufficient connections, damaged components, or even the presence of foreign materials on the PCB surface. By enabling immediate detection of deviations, the AOI system allows potential issues to be corrected at an early stage of the manufacturing process.
X-Ray Inspection
Detection of Hidden Defects
When necessary, optical inspection is complemented by X-ray inspection. The Phoenix X|aminer X-ray system enables the examination of hidden solder joints from multiple angles, which is particularly important for BGA packages, integrated circuits, and other components with concealed connections.
X-ray inspection makes it possible to determine the quality of solder joints, identify excess or insufficient solder material, and reveal defects that cannot be observed through visual inspection alone. When required, the inspection images can be recorded and provided to customers as part of the production documentation. This technology can also be applied to the inspection of supplied components, supporting quality control throughout the supply chain.
Key Advantage in Prototype and Serial Production
AOI Optical and X-ray inspection technologies are particularly valuable during prototype manufacturing, where the early detection of design or soldering issues can lead to significant cost savings. Identifying potential problems during the development phase allows design corrections to be implemented before serial production begins.
In serial production environments, continuous inspection ensures stable and repeatable manufacturing quality. Early detection of hidden defects reduces scrap rates, minimizes the need for rework, and contributes to the long-term cost efficiency of the manufacturing process.
Documented and Fully Traceable Quality
The results of AOI optical and X-ray inspection are documented, ensuring full traceability of the manufacturing process. This is especially important for quality-critical applications and products designed for long service lifetimes.
At ElektroMont, inspection technologies are not used solely for defect detection. They form an integral part of a controlled manufacturing environment designed to ensure stable, reliable electronics production.
