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

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

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.

Abstract

Purpose

The purpose of this study/paper is to describe the implementation of a six-month schema therapy awareness (STA) group. Research supporting individual schema therapy (ST) as an effective intervention for personality disorder is growing steadily within a number of settings including with forensic patients. Alongside individual ST, positive results have been reported for group ST. However, to the best of the authors’ knowledge, no current published research exists with regard to the use of group ST within forensic populations and more specifically within a low secure environment.

Design/methodology/approach

This paper describes the implementation of a six-month schema therapy awareness (STA) group with individuals situated within a low secure environment.

Findings

For individuals transitioning into the community from a secure setting, the focus of risk management should attempt to move away from external controls towards more of a reliance on internal factors. In ST, this is achieved by understanding the role of schema modes (and underlying schemas) that are linked to an individual’s offences/risk and developing this understanding into a coherent and accessible formulation for the individual to make changes.

Research limitations/implications

Further robust research evaluating clinical change is recommended as the next step.

Practical implications

The group protocol is described along with the challenges and potential solutions experienced during the implementation. This provides an opportunity for other professionals to replicate this approach in the future.

Originality/value

With regard to group ST within forensic populations, the research is sparse at present and this study focusses on practical application of theory and the challenges of operationalising a STA group.

Abstract

This article investigates the intellectual roots of perestroika. Mikhail Sergeyevich Gorbachev, the architect of perestroika claims that his programmes and policies are aimed at a revolutionary transformation of the Soviet economy from an overly centralised command system of management to a democratic system based mainly on economic methods and on an optimal combination of centralism and self‐management. To facilitate the restructuring process, Gorbachev simultaneously initiated two sweeping political reforms: glasnost (no “radical change is possible without it”); and demokratizatsiya (”there is no present‐day socialism, nor can there be, without democracy”). Therefore, prominent features envisaged by perestroika would presumably include: an optimal combination between centralism and self‐management, that would imply decentralisation in the economic management of the country; replacement of administrative methods by economic methods, that would emphasise economic incentives and market processes more than machineries of central planning; democratisation and openness in Soviet society, aimed at guaranteeing greater democratic rights for citizens, and pluralism in governmental and political processes.

Abstract

Purpose

The purpose of the paper is to suggest effective choices for key decisions when pursuing a programmatic research strategy in management, spirituality and religion (MSR). An example is provided of how the suggestions can be used.

Design/methodology/approach

Suggestions for research were gleaned from current sources in research methodology. The example provided was a study of 398 employees who were surveyed on spirituality, job satisfaction and intent to leave their job. Structural equation modeling (SEM) was used to test three research hypotheses.

Findings

Using item analysis, exploratory factor analysis and SEM can be a way to pursue research using variables related to spirituality and religion.

Originality/value

A programmatic research strategy employing SEM can effectively model how spirituality/religious variables directly and indirectly affect outcomes significant to the organization.
