Why do we need to perform PCBA AOI quality checking

Efficiency and speed: AOI systems can inspect a large number of electronic components and solder joints in a short period of time. Compared to manual inspection, AOI provides higher efficiency and speed, which helps accelerate the production process.

High precision and consistency: AOI systems have high-precision image processing and analysis capabilities, capable of detecting small defects and problems. Its consistency ensures consistency checks on the same standards in mass production.

Reduce human errors: Due to the subjective factors and fatigue that may affect manual inspections, errors may occur. The AOI system eliminates these human errors and improves the accuracy of inspections through algorithmic analysis.

Comprehensive inspection: AOI can comprehensively inspect the entire PCBA, including solder joints, components, identification, and other key features. This ensures a comprehensive evaluation of all aspects of the circuit board and reduces the possibility of omissions.

Real time feedback: The AOI system provides real-time feedback, allowing problems to be quickly discovered and resolved. Timely detection and feedback can help reduce the production of non-conforming products, reduce costs, and waste resources.

Save labor costs: AOI systems can replace some manual inspection work, reduce labor costs, and allocate human resources to higher-level tasks such as engineering design and quality management.

Adapting to complex designs: Modern PCB designs are becoming increasingly complex, with components becoming smaller and smaller. The AOI system can adapt to this trend, provide highly accurate inspections, and meet the requirements of modern electronic manufacturing.

Tracking and recording: The AOI system is able to track and record the inspection results of each PCBA. This provides data on the production process, which helps with quality management, traceability, and continuous improvement.

PCBA AOI testing covers a wide range of testing content, including but not limited to the following aspects:

Solder joint inspection:
This inspection item is used to verify the quality of solder joints and detect whether the welding, solder paste coverage, position, defects, etc. on the pads meet the requirements of the specification.

Component position detection:
By detecting the accuracy of component position, ensure that components are correctly and accurately installed at the designated location to avoid incorrect connections and short circuit problems during circuit board assembly.

Pad and welding quality inspection:
Detect issues such as pad and welding quality, solder coverage, offset, etc. to ensure the stability and reliability of welding.

Defect detection:
Detect defects on the surface of the circuit board, such as scratches, cracks, stains, etc., to ensure that the circuit board is not affected by these defects and at the same time improve the appearance quality of the product.

Process control:
Through real-time monitoring and recording of test data, the production process can be adjusted and optimized in a timely manner to improve quality stability and consistency. PCBA AOI inspection plays a vital role in the electronics manufacturing industry. It can improve product quality, reduce defect rates and costs, and improve manufacturing efficiency.

By using advanced optical technology and algorithms, PCBA AOI inspection ensures product performance and reliability, meets market and customer needs, and provides high-quality electronic products.
