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.

In an era where crime rates and societal concerns about safety have significantly heightened, understanding the psyche of offenders and the dynamics of victimisation has never been more crucial. The Department of Psychology at the Easwari School of Liberal Arts organised an enlightening guest talk delivered by Dr Amrutha Karyil, an expert in Crimes against Women and Children, Victimology, and Victim Assistance. Dr Karyil’s insightful discourse shed light on the complex world of victim profiling, engaging students in a thought-provoking discussion about its historical evolution, methodologies, and ethical dimensions.

Dr Karyil in her presentation offered a fascinating overview of the history of profiling, tracing its roots back to the Salem Witch Trials and the harrowing case of Jack the Ripper. She elaborated on how profiling serves as a form of behavioural evidence analysis, focusing on the crucial intersection of psychology and criminal investigations. By examining crime scenes, victim backgrounds, and the modus operandi of offenders, profiling seeks to narrow the suspect pool, providing law enforcement with valuable insights into potential perpetrators.

During the talk, Dr Karyil detailed five major types of profiling: psychological, suspect-based, geographical, crime scene, and equivocal death analysis. She stressed that while profiling can be an invaluable investigative tool, it is by no means definitive. Rather, it aids in understanding the underlying patterns of criminal behaviour and assists investigators in their pursuit of justice.

Dr Karyil further explored the broader implications of victim profiling in crime scene analysis. She shared compelling statistics and characteristics of victims targeted by notorious serial killers, urging attendees to recognise the patterns and signatures that often reveal themselves in such cases. The talk underscored the necessity of fostering awareness and specialised training in addressing severe offences, reflecting on the ethical responsibilities that come with careers in forensic psychology.

The event also served as a catalyst for vibrant discussions about the ethical challenges. Students expressed their interest in diverse career paths such as crime scene analysis, offender profiling, and counselling within the criminal justice system. Dr Karyil’s expertise and engaging delivery inspired many to consider how they might contribute to this vital area of society, whether through research, advocacy, or direct service.

The Department of Electronics and Communication Engineering is pleased to announce the publication of a significant research paper by Dr Anirbhan Ghosh, Assistant Professor, exploring MIMO channel capacity at high frequencies (300 GHz), which holds great potential for beyond 5G and 6G networks. The paper “MIMO Channel Capacity Measurement in Open Square Hot Spot Access Scenarios at 300 GHz” published in the Q1 journal IEEE Wireless Communication Letters, investigates data transmission in three different line-of-sight (LoS) scenarios and contributes to building the next generation of communication networks, which will have a significant positive impact on society by improving connectivity, supporting technological advancements, and promoting economic development.

Abstract

This letter explores the possibility and effectiveness of using multiple communication paths for futuristic outdoor networks, focusing on three scenarios: clear line-of-sight (LoS), partially obstructed line-of-sight (OLoS), and completely blocked line-of-sight (NLoS). A study was conducted at a high frequency of 300 GHz to measure how many useful communication paths are available for transmitting data simultaneously. Based on the results, the average data transmission capacity for these paths was calculated, both with and without the help of passive reflecting surfaces (PRS). The findings show that using multiple antennas significantly boosts the average data capacity, and PRS further enhances this improvement.

Practical Implementation of the Research

The results align with the design of high-frequency, ultra-high-speed, low-latency, reliable communication envisioned for several futuristic applications beyond 5G and 6G Networks.

Dr Manaswini Sen, Assistant Professor at the Department of History, has published an insightful paper tracing the ideological and intellectual output of women trade unionists in late colonial Bengal. Her research paper titled “(Re)Inventing Feminism within the Discourse of Class Struggle: Women and Intellectual History in the Trade Union Movement of Late Colonial Bengal (1920–1947)”, published in the prestigious Journal of the History of Women Philosophers and Scientists, offers a novel perspective on understanding the class struggle, anticolonial discourse in the patriarchal society of colonial Bengal.

Abstract

This paper envisages (re)constructing the intellectual praxis of women trade unionists in late colonial Bengal. By arguing how political practice habitually translates to political thought, the paper devises a methodology to address the gendered discourse of intellectual history in the Global South. It focuses on intellectual output, primarily journal articles of women trade unionists like Santoshi Kumari Gupta, Maitreyee Bose, and Kanak Mukherjee, to trace a genealogy of how class struggle was perceived by women labour activists across the ideological spectrum of nationalism, socialism, and communism between 1920 to 1947 in Bengal. The piece is an effort to transcend the manifold marginalisations that plague the establishment of feminine political praxis within the regulating structures of colonialism and capitalism. In the process, it bids to unfold an alternative narrative of the anti-colonial, anti-capitalist, and anti-patriarchal narrative of the decolonisation of South Asian intellectual thought.

Research, Collaboration and Future Research Plans

The research strives to bring to the forefront the intellectual contributions of three female trade unionists in the late colonial period to trace the evolution of discourses on anticolonial class struggle from a gendered perspective. With the global turn in intellectual history, there is an augmented effort at amplifying the ‘small voices of history’. The inherent socio-cultural predicaments in our society make it inordinately challenging to trace conventional sources for mapping the intellectual endeavours of women. This paper aims to rectify this gap by reconstructing women labour activists’ intellectual practises and literary output in the early 20th century. In the process, the research tries to bring forth narratives of anticolonialism, which drowns in the overwhelming presence of nationalism in the discourses of decolonisation of South Asia. This paper was the result of academic exchanges with professors of Benaras Hindu University, Dr B.R. Ambedkar University, Delhi, and the University of Paderborn, Germany.

Dr Sen primarily researches marginal anticolonial epistemological traditions of South and South East Asia. Her thesis on the evolution and dissemination of socialism in late colonial Bengal, which focuses on an intellectual history of trade unionism, forms the basis of her first monograph. However, she is now focusing on the transnational and transcontinental intellectual networks of a wide spectrum of leftist labour activists and proto-nationalists and the ways these fringe intellectual traditions interacted with each other and nationalism. Based on a rich archive across India and Europe and a plethora of alternative sources, she tends to devise new methodological interventions in the field of Global Intellectual History, making labour history more accessible and relevant in scholarly circles.
