In today’s fast-paced technological world, ensuring the quality and reliability of electronic devices is essential. Associate Professor Dr Ramesh Vaddi and his research Scholar Mr Vinod Kumar Ancha from the Department of Electrical and Electronics Engineering introduce an innovative system for real-time detection and classification of defects in PCBAs, leveraging advanced machine learning techniques. Their research titled, “System And Method For Real-Time Detection And Classification of Defects in Assembled Printed Circuit Boards (PCBA)” was published in the Patent Journal with Application number 202441045761.

Abstract:

This study presents a new system for real-time detection and classification of defects in Assembled Printed Circuit Boards (PCBAs), which are critical in electronic products and systems. It employs an efficient model with pretrained weights to detect defects for enhanced quality control. The model is initially trained and fine-tuned on a computer, then deployed on a compact computing board. For real-time imaging, a high-definition USB camera is connected to the system, allowing direct defect identification without the need for external devices. The output is shown on a monitor, with the PCBA image featuring clearly labeled boxes to indicate the type and location of defects. This method offers a streamlined approach to defect classification, helping to improve the quality control process in electronics manufacturing.

Explanation of the Research in layperson’s terms:

This research focuses on finding defects or flaws in Assembled Printed Circuit Boards (PCBAs). Which are the “backbone” of most electronic devices, like computers and phones. This system uses a powerful computer model to “look” at these boards and quickly identify any defects, like missing holes, mouse byte, open circuit, short circuit, spur and spurious copper in real-time. The research starts by training this model using a deep learning object detection model on a regular computer, teaching it to recognize what a normal PCBA looks like and what various defects might look like. Once it’s ready, we transfer the model to a small, efficient computer edge board, which does all the processing. A camera is used to capture images of the PCBAs, and the system analyzes these images to find respective defects. The results are displayed on a screen, where it clearly marks where the defects are and what kind of defects they are. Overall, this system helps companies detect defects in their electronics manufacturing process quickly and accurately, which can save time, reduce waste, and improve the quality of their products.

Practical Implementation:

The practical implementation of our research involves deploying a system for real-time detection and classification of defects in Assembled Printed Circuit Boards (PCBAs) a crucial component in nearly all electronic devices. By using advanced Deep learning techniques, our system can quickly identify manufacturing defects, allowing electronics manufacturers to detect the defect early in the production process. This can lead to significant improvements in quality control, reduced waste, and lower production costs. By improving quality control in electronics manufacturing, the system can help reduce electronic waste, which is a significant environmental concern. Early detection of defects also reduces the chances of faulty electronic products reaching consumers, thereby improving safety and reducing the need for product recalls. Additionally, the efficiency and accuracy of our system could lead to more reliable electronics, contributing to greater consumer trust in electronic products. This, in turn, could encourage companies to invest in higher-quality manufacturing processes, ultimately leading to a more sustainable and responsible electronics industry.

Collaborations:

To develop our system, we first trained a computer model to recognize defects in Assembled Printed Circuit Boards (PCBAs). This training process involved feeding the model a large dataset of PCBA images, some with defects and some without. By analyzing these examples, the model learned to identify common defects, like Missing hole, mouse byte, open circuit, short circuit, Spur and Spurious copper. Once the model was trained, we implemented it in a real-time setting. This meant integrating it with equipment that could inspect PCBAs as they were being produced. The system used a camera to capture images of each PCBA and then applied the trained model to analyze those images, checking for any defects. With the model running in real-time, the system could immediately detect issues and alert the manufacturing team, allowing them to correct problems on the spot. This approach helped improve the quality of the final product and reduced the chances of defective electronics reaching consumers. It also sped up the quality control process and reduced waste, making the entire manufacturing process more efficient.

Future Research Plans:

Our future research plans focus on enhancing and expanding our system for defect detection in Assembled Printed Circuit Boards (PCBAs):

Model Optimization: We aim to further refine our machine learning model to improve accuracy and speed. This includes experimenting with different architectures and training techniques to boost performance.

Expanded Defect Library: We plan to gather a more extensive dataset of PCBA defects, allowing our model to identify a wider range of issues. This will make the system more versatile and capable of handling various manufacturing environments.

Real-World Testing: We intend to test our system in a broader range of manufacturing settings to ensure its robustness and adaptability. This will help us understand how it performs in diverse real-world scenarios and how we can fine-tune it for optimal results.

Integration with Manufacturing Systems: Our goal is to integrate our system with other manufacturing processes and technologies. This will allow for seamless communication between defect detection and other quality control systems, enhancing the overall manufacturing workflow.

Automation and Robotics: We’re interested in exploring the use of automation and robotics to streamline the defect detection process. This could lead to a more automated manufacturing line, reducing human intervention and potential errors.

Collaboration and Partnerships: We plan to collaborate with more industry partners and academic institutions to accelerate our research and development. These partnerships will provide valuable insights and resources for advancing our system.
