Abstract
Purpose
The purpose of this paper is to describe key failure mechanisms observed during the development of the advanced packaging technology. Extensive accelerated stress tests are conducted to collect failure data and understand failure characteristics and failure trends. The results will be useful for design improvement and failure rate predictions.
Design/methodology/approach
High density chip scale packages (CSP) are developed to meet the needs for high performance and small form‐factor products, but with reduced process procedures and product cost. Test‐to‐failure approaches are applied to evaluate the failure rate and reliability models instead of compliance qualification testing approaches.
Findings
The study shows Cu‐trace cracking failure can be treated as random failures and analyzed using a constant failure rate approach. The acceleration factor for the Cu‐trace cracking failure mechanism exhibits a large power exponent comparing to the parameters used in reference models. In addition, the solder joint failure data collected through the study do not fit well with the well‐known solder fatigue life model. Moreover, the test results affirm the test‐to‐failure approach adopted in data collection is providing more accurate failure characteristics compared to the compliance qualification testing approach.
Practical implications
The paper shows that the reliability performance of package technology can be improved by enhancing the package design, improving manufacturing processes and materials optimization.
Originality/value
This is an original research paper and the test‐to‐failure approach in the reliability study helps provide realistic reliability predictions.

Abstract
Purpose
In today's electronic package development cycle, activities are managed by multiple participants in the supply chain, which might have different quality and reliability impacts to the end product. As a result, the reliability risk is much higher for companies who do not have insight into and/or control over the products received. The purpose of this paper is to show how design‐for‐reliability (DFR) approaches will come into play to manage the risk.
Design/methodology/approach
In this paper, DFR approaches for package development will be discussed from the perspective of the original equipment manufacturers (OEMs). DFR practices through the package development cycle will be described based on key development modules. A case study for flip chip ball gris array package development using an advanced Cu/Low‐k silicon technology will be presented. Key measures to help control the quality and improve the reliability will be presented.
Findings
The proposed methodology significantly improves component and package reliability through the engagement in design, manufacturing, assessment and system evaluation.
Originality/value
The paper discusses the research results and the proposed DFR methodology will be helpful for fabless design houses, electronics manufacturing service (EMS) partners in the supply chain, and OEMs to manage the reliability of the products.

Abstract
Liquid encapsulation techniques have been used extensively in advanced semiconductor packaging, including applications of underfilling, cavity‐filling, and glob top encapsulation. Because of the advanced encapsulation materials and the automatic liquid dispensing equipment involved, it is very important to understand the encapsulation material characteristics, equipment characteristics, encapsulation process development techniques in order to achieve the encapsulation quality and reliability. In this paper, the authors will examine the various considerations in liquid encapsulation applications and address the concerns on material characterization, automatic liquid dispensing equipment/process characterization and the encapsulation quality and reliability. The discussions will be helpful for future material and process development of semiconductor packages.

Abstract
The outbreak of the SARS-CoV-2 (COVID-19) pandemic has caused significant disruptions to academic activities in educational institutions across countries of the world. In the context of transnational higher education (TNHE), the pandemic has led to major shifts in face-to-face teaching and learning, students’ support services and student engagement. While a number of scholarly studies have examined the effect of the pandemic on education provision across different educational levels, not much has been done to address existing gaps in how academic leaders could support the transformation of the TNHE sector to respond to current disruptions. In order to address these gaps, the current study adopts a case study approach to examine the complex and evolving academic leadership roles in TNHE institutions in Ghana with respect to remote teaching and learning and virtual team activities. The current study addresses the following questions: What academic leadership approaches are essential to developing innovative practices in host TNHE in order to meet the learning needs of students during and after the pandemic? How can transformational leadership approaches interface with institutional theory to provide new direction for transforming TNHE during and after the pandemic? How can academic leadership roles support the transformation of TNHE during and after the COVID-19 pandemic? As a major contribution for addressing gaps in academic leadership roles in TNHE environments especially during COVID-19, the current study proposes an eight-component transformation model. The study concludes by arguing that the challenges facing TNHE especially during the current period of disruptions will require a transformative and innovative academic leadership approach that would ensure that education delivery addresses current and future students’ learning needs.

Abstract
Purpose
This paper aims to provide an action-orientated reflection for promoting gender equality in hospitality, based on Bradley’s (2013) approach that considers the operation of gender in the “production” and “reproduction” spheres of social life. To that end, it reflects on women’s career development in hospitality based on the Western perspective.
Design/methodology/approach
A two-stage thematic analysis of a public research seminar on gender issues in tourism and hospitality were used to explore issues of women’s career development within the intertwining spheres of “production” and “reproduction”.
Findings
Three themes, namely, culture of an open dialogue, bringing men into the equation and educating the future workforce, emerged from data to propose new insights on “what can be done” about gender equality in tourism and hospitality, including practical suggestions for transformations of gender relations in organisations.
Research limitations/implications
This paper contributes new knowledge on women’s career development in the hospitality industry by proposing recommendations to address gender gaps including fostering a culture of an open dialogue based on an inclusive listening environment, recommending changes to organisational policies and culture and integrating the subject of gender into tourism and hospitality curriculum.
Originality/value
By proposing a sociological perspective of gender in hospitality employment informed by Bradley (2013), this study challenges the traditional masculinity and the long-standing gender labour division through education, organisational and daily practices thus tackling fundamental gender issues.

Abstract
This chapter is an overview of herstorical, political and theatrical developments in South Africa. It provides an overview of the background to the herstory of South Africa from 1912–1993.
Dates are included which have relevance to the herstory of South African Women; for example, 1912 was the year of the formation of the African National Congress (ANC); in 1913 Charlotte Maxeke led a march against pass laws for African women; the Native Land Act of 1913 stated that natives were no longer able to buy, sell or lease outside the stipulated reserves; the Influx Control and The Natives Urban Act of 1923 and amendments to the Act in 1937 had devastating consequences for African women as it severely restricted their movements from rural to urban areas. The year 1930 is important because this was when white South African women acquired the vote which gave political activists such as Helen Joseph and Helen Suzman a political voice. In 1948 the ANC Women’s League (ANCWL) was formed. Political events from the 1970s through to 1993, demonstrate how the Black Consciousness Movement (BCM), the African National Congress (ANC), other anti-apartheid organisations and the apartheid government realised the effectiveness of theatre as a political weapon

Abstract
The evolution of interorganizational networks is shaped by micro and macro processes. At the micro level organizational dyads negotiate relationships in light of their own cost—benefit analysis. At the macro level resources flow through networks and are mobilized by coalitions. Current research is beginning to examine integrating mechanisms which link network dynamics to dyadic relationship formation. In this paper we examine interorganizational brokerage as an integrating mechanism linking micro and macro network processes. We focus on the formation of networks in the global television industry. The Children's Television Network (CTW) has licensed and co‐produced its flagship program “Sesame Street” in many countries around the globe. Recently, it has expanded beyond a strategy based on direct first‐order linkages to one of brokerage and interorganizational entrepreneurship, entailing the formation of second‐order linkages—linkages between organizations with which CTW has direct first‐order relationships. In the aftermath of the Oslo Peace Agreement, CTW acted as a broker and sponsor of a joint venture between Israeli and Palestinian broadcasters. The main challenge facing CTW was a high degree of distrust between the parties motivated by fears of opportunistic exploitation. Such fears typically result in high transaction costs, making joint venture formation difficult, if not impossible. In its capacity as broker, CTW worked to reduce transaction costs. This was done by providing resources where needed, and by facilitating interaction and trust building between the parties. We describe CTW's tactics during the formation of this joint venture, and we analyze the outcome of the joint venture from the point of view of CTW's overall strategy. We conclude by discussing CTW's network and brokerage strategy in the aftermath of the joint venture.

Abstract
Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.
