This paper presents an application of the physics‐of‐failure design philosophy to flip‐chip bonds in a microelectronic package. The physics‐of‐failure philosophy utilises knowledge of the life‐cycle load profile, package architecture and material properties to identify potential failure mechanisms and to prevent operational failures through robust design and manufacturing practices. The potential failure mechanisms and failure sites are identified in this paper for flip‐chip bonds, and an approach is presented to prevent the identified potential failure mechanisms by design. Finally, quality conformance issues are discussed to ensure a robust manufacturing process and qualification issues are addressed to evaluate the reliability of the designed flip‐chip bond.

As speed and complexity of electronic systems increase, the interconnect density has become the critical limitation to the performance of electrical systems. The performance of computing and switching systems can be increased by optimizing the interconnect density and throughput. At the board to board level, electrical interconnects at high speeds require a bulky and expensive backplane. At the chip to chip area, the allocation of interconnects limits the performance of the chips. Electrical lossy lines limit the maximum interconnect distance due to reflections, risetime degradation, increased delay, attenuation and cross talk . Optical interconnects present the possibility of solving the interconnect problems by potentially achieving a high bandwidth and high volume density of channels. At high data rates (greater than 1 Gb/s) several channels may operate with negligible mutual interference.

Dr Nihal Sinnadurai has taken up his new post as Professor of Electronics Technology at Middlesex University and head of its Microelectronics Centre.

During the first half of this year the Association has continued to expand its exhibition programme by increasing its presence at overseas shows. Two DTI sponsored joint venture groups have been formed, one to Nepcon West, the other to Nepcon Beijing. Anaheim saw the biggest UK group for over 10 years, with CEMA taking three separate blocks in different sectors of the show. There is no doubt from the reception we received that CEMA is now firmly established at Nepcon West. We enjoyed tremendous support from both the British Consulate and the British‐American Chamber of Commerce with their President making several visits to the CEMA booth.

The learning outcomes of this study are to examine the financial performance of Bangalore Metro Rail Corporation Ltd. (BMRCL) during past five years, to compare the financial performance with the initial projections, to identify the causes of deviations in the performance, to recommend the measures to improve financial performance and to apply the learning from the BMRCL project to other similar upcoming projects in India.

BMRCL has been struggling to perform as per projections made in the initial detailed project report. The situation has further worsened because of the COVID-19 pandemic and its post-impact on the overall economic level of activity. Ramana Rao, the consultant for infrastructure projects, was worried after reading a news article which deemed the project a white elephant. Various articles published in the newspaper also reported that BMRCL was incurring a loss of Rs 45 lakhs every day. The consultant worried about the sustainability of the project. He wanted new ideas and plans which could turn around these losses and convert them into profitable ones. He, however, does not have any immediate plans to execute and is therefore in a dilemma about how a project that was launched with so much fanfare could be made profitable. Because of COVID-19 pandemic, BMRCL’s financial situation, which although improving, had taken a significant hit. It looked like the corporation might need government assistance to cover its losses. The transport utility suffered a loss of Rs 170 crore, as a result of a decline in ridership as well as other revenue sources including parking fees and leasing revenues. This amounted to a daily loss of Rs 1 crore. The pressure on revenues was putting the officials in a tight spot about meeting the company’s debt obligations and market borrowings.

The case study aims to enable participants to understand financial performance and viability of large-scale projects such as metro rail in India.

This study examines various aspects of green energy management operations in India and reports the current state, potential avenues and barriers for green energy management.

This study performs an extensive literature review and covers the several aspects of green energy management operations.

The findings report the current state of various aspects of green energy management operations such as: procurement, manufacturing and distribution and provides the viable business models. It further explains the various facilitators and barriers of green energy management and reports the opportunities and challenges that exist in developing and managing green energy supply chain.

The study is pioneer in providing a comprehensive view of developing and managing green energy operations in India. The study is useful to various organisations on drafting strategies to effectively adopt and manage green energy. The study is also useful in policy formulation for promoting green energy use. This article also set as a base for future researchers working in the area of green energy.

The purpose of this study is to identify Offshore Wind Energy (OWE) as a key technology that could drive countries toward achieving climate goals. However, there are multiple challenges that this sector faces.

This study aims to identify the challenges faced by the sector globally by systematically reviewing the existing literature in global context and portraying it in the Indian context. Factors are identified using content analysis.

Results suggest high levelized cost of energy as the most discussed challenge for the growth of OWE. Insufficient financial support and policy, initial capital and inadequate technology formed the second, third and fourth most discussed challenges respectively.

To reduce the cost of OWE, the distribution companies in India could adopt feed-in tariffs (FiTs) in the early stages of development and make OWE procurement mandatory. The renewable purchase obligation (RPO) in India is specific to solar and non-solar; policy should accommodate offshore wind-specific RPO targets for each state to reach the 2030 target of 30 GW from OWE.

To the best of the authors’ knowledge, this is the first attempt to study the challenges of OWE development from a global perspective and portray these major challenges in the Indian context and uses content analysis from the existing literature to ascertain the major roadblocks for the development of OWE.

The study identifies the unexplored gap in literature that includes futuristic challenges for OWE from climate change. Future studies can explore the possibilities of forecasting based on climate change scenarios and rank the challenges based on their relevance caused by possible damages.
