Inspection Principle of Online PCBA Double-sided AOI Equipment

2022-11-07

Principle of the device: Through the upper and lower two high-precision cameras, moving pictures of the same board. Take convolutional neural network algorithm to process the image, and intelligently determine the bad components and bad solder.

AOI is an automatic optical inspection, as the name suggests, is a means of automatic detection through optical system imaging, is one of the many automatic image sensing inspection technology, the core technology point how to obtain accurate and high-quality optical images and processing. The biggest advantage of AOI inspection is to save manpower, reduce costs, improve production efficiency, unify testing standards and eliminate human factors interference, to ensure the stability, repeatability and accuracy of the test results, timely detection of product defects, to ensure the quality of shipments.

Application scenario: SMT section after reflow soldering, DIP section after wave soldering, pre-packaging inspection.

Product advantages :

1. Save manpower, can replace the visual inspection station before final inspection.

2. Effective card control before packaging, intercepting bad, avoiding outflow and improving quality.

3. Can retain the front and back of the card photos before packaging, to achieve data traceability.

4. streamlined programming process, minimalist interface, and support for one-key batch modification of parameters.

5. Double cameras take photos when asynchronous, avoiding light source interference and improving detection beats.

6. strong anti-interference ability, high detection rate, low false alarm rate.

7. Centralized control, can realize the interconnection of multiple devices.

Online PCBA double-sided AOI inspection equipment inspection technology was born out of the background of the high degree of integration and refinement of electronic components, detection speed and efficiency, detection of zero defects in the development of demand. In the artificial intelligence technology and big data development progress today, AOI inspection is not only a detection device, a large number of bad results for classification and statistics, you can find the cause of the occurrence of bad, in the process improvement and production yields are gradually playing a more important role, therefore, it can be expected that the future of AOI inspection technology will play an increasingly important role in the semiconductor and electronic circuit inspection Therefore, it is expected that AOI inspection technology will play an increasingly important role in semiconductor and electronic circuit inspection.
