Abstract
Purpose
The purpose of this paper is to discuss the reliability of board level Sn‐Ag‐Cu (SAC) solder joints in terms of both thermal cycling and drop impact loading conditions, and further modification of the characteristics of low Ag‐content SAC solder joints using minor alloying elements to withstand both thermal cycle and drop impact loads.
Design/methodology/approach
The thermal cycling and drop impact reliability of different Ag‐content SAC bulk solder will be discussed from the viewpoints of mechanical and micro‐structural properties.
Findings
The best SAC composition for drop performance is not necessarily the best composition for optimum thermal cycling reliability. The content level of silver in SAC solder alloys can be an advantage or a disadvantage depending on the application, package and reliability requirements. The low Ag‐content SAC alloys with different minor alloying elements such as Mn, Ce, Bi, Ni and Ti display good performance in terms of both thermal cycling and drop impact loading conditions.
Originality/value
The paper details the mechanical and micro‐structural properties requirements to design a robust bulk SAC solder joint. These properties provide design and manufacturing engineers with the necessary information when deciding on a solder alloy for their specific application.

Abstract
Purpose
The purpose of this paper is to investigate the effects of small additions (0.1 and 0.3 wt%) of Fe on the bulk alloy microstructure and tensile properties of low Ag‐content Sn‐1Ag‐0.5Cu lead‐free solder alloy.
Design/methodology/approach
Sn‐1Ag‐0.5Cu, Sn‐3Ag‐0.5Cu and Sn‐1Ag‐0.5Cu containing 1 and 3 wt.% Fe solder specimens were prepared by melting pure ingots of Sn, Ag, Cu and Fe in an induction furnace and subsequently remelting and casting to form flat dog‐bone shaped specimens for tensile testing. The solder specimens were subjected to tensile testing using an INSTRON tester with a loading rate 10‐3 s‐1. To obtain the microstructure, the solder samples were prepared by dicing, molding, grinding and polishing processes. The microstructural analysis was carried out using scanning electron microscopy/Energy Dispersive X‐ray spectroscopy. Electron backscatter diffraction (EBSD) analysis was used to identify the IMC phases.
Findings
In addition to large primary β‐Sn grains, the addition of Fe to the SAC105 alloy formed large circular shaped FeSn2 IMC particles located in the eutectic regions. This had a significant effect in reducing the elastic modulus and yield strength and maintaining the elongation at the SAC105 level. Moreover, the additions of Fe resulted in the inclusion of Fe in the Ag3Sn and Cu6Sn5 IMC particles. The additions of Fe did not have any significant effect on the melting behaviour.
Research limitations/implications
The paper provides a starting‐point for studying the effect of minor additions of Fe on the drop impact and thermal cycling reliability of SAC105 alloy considering the bulk alloy microstructure and tensile properties. Further investigations should be undertaken in the future.
Originality/value
The effect of Fe addition on the bulk alloy microstructure and tensile properties of the SAC105 alloy has been studied for the first time. Fe‐containing SAC105 alloy may have the potential to increase the drop impact and thermal cycling reliability compared with the standard SAC105 alloy.

Abstract
Purpose
This paper aims to identify the critical success factors of the continued usage of digital library (DL) successful implementation from the perspective of users with organisation support factors as key antecedents.
Design/methodology/approach
Based on the extensive literature review, this study has constructed a conceptual framework based on organisational support perspectives and updated Delone and McLean’s information system success model. A pilot study was carried out on a sample of 105 respondents from military-context. A survey instrument including 22 measurement items was designed to identify the level of DL information system (IS) successful implementation practices in military context. Descriptive statistical analysis and reliability analysis were used to analyse the data with SPSS software.
Findings
The findings indicate that training and education, DL environment and communication support, continuation of usage intention, net benefits and user satisfaction are the critical success factors that play key role in ensuring the continued usage DL successful implementation in military context. The military-context DL needs to obtain critical success factors of DL practices implementation to sustain its continued usage, particularly for the active users of its members.
Research limitations/implications
This study only considered the military personnel who have visited the five main military libraries. For practical implications, the development of instruments in this study may be valuable tools to evaluate DL in other DL settings in Malaysian context other than academic settings.
Originality/value
This study makes a new contribution to DL IS successful implementation practices in military context. This study also provides important information for decision-makers involved in DL IS successful implementation practices and provides useful reference for future researchers in this research area.

Abstract
Purpose
This paper aims to examine the impacts of corporate entrepreneurship, national policies and supply chain collaboration on the innovativeness of manufacturers of light emitting diode (LED) in Malaysia.
Design/methodology/approach
The data were collected by using questionnaire survey from the manufacturers involved in the various echelon of the supply chain. The data collected were analyzed by using partial least square (PLS).
Findings
Corporate entrepreneurship plays a moderating role in the relationship between national policies, supply chain collaboration and innovativeness.
Research limitations/implications
This study is only focusing on the supply chain of LED in Malaysia; hence, the results may not be suitable to be generalized to wider populations.
Practical implications
The findings of this study could help the local companies to understand on how, as entrepreneurs, they could expand from small scale to contract manufacturers through enhancing innovativeness. This is important as failure to do so may cause them to be excluded from the global supply chain.
Originality/value
This study expands the existing literature by providing empirical evidence from the perspective of an emerging country, namely, Malaysia. It also attempts to close the gaps by examining the role of corporate entrepreneurship as the moderating variable.

The case is suitable for use in the topics related to the functions and roles of hedging and the Islamic derivatives/hedging instruments.
Abstract
Subject area
The case is suitable for use in the topics related to the functions and roles of hedging and the Islamic derivatives/hedging instruments.
Study level/applicability
The case is designed for undergraduate students, taking courses in Islamic Banking, Islamic Finance and Risk Management for Islamic Banking Institutions.
Case overview
This case describes the theory and application of Islamic Cross Currency Swap (ICCS) in the market. Having this understanding enables case analysts to understand the functions and roles of hedging and the Islamic derivatives or hedging instruments of ICCS comprehensively. The case begins with Yusof, the new finance officer of Al-Yemeni Sdn. Bhd to analyse the permissibility of hedging and derivatives to hedge against currency fluctuations from Islamic perspective. Yusof had to complete the report before the Board of Director's quarterly meeting, which was within a week. Having in mind that the company's mission was to be a Shariah-compliant stock by 2012, Yusof was responsible for ensuring that the company was administrated in an Islamic way. Besides, he also had to ensure that the company generated income and profit as planned. In doing so, he had to strategise all possible risk exposures that could be mitigated or hedged. This case ends by giving the case analyst information on ICCS offered by Al-Rizky Bank Berhad (ARBB). In this case, Yusof had to find out whether hedging is allowed in Islam. What are the Islamic derivatives? What are the different views of Shariah scholars on various types of derivatives? What is the modus operandi of ICCS? Is the ICCS offered by ARBB Shariah compliant? What are the possible risk exposures being hedged in ICCS?
Expected learning outcomes
To provide exposure on the concepts of hedging from Islamic perspectives; to provide exposure on the concepts of Islamic derivatives/Islamic hedging instruments; to stimulate understanding on the modus operandi of ICCS in ARBB; and to help case analysts understand what makes the Islamic hedging instruments become Shariah compliant.

Abstract
Purpose
The purpose of this paper is to examine potential determinants of halal perception and to validate the mediating model of halal perception on purchasing decision of Malaysian consumers.
Design/methodology/approach
This study uses a survey to obtain the relevant data. The survey involved self-administration of questionnaires to 420 consumers and 96 per cent responded. The questionnaire consists of four sections designed to obtain information on demography, halal perception, determinants of halal perception and purchase decision.
Findings
The main finding reiterates the role of credible signals in credence items purchased as suggested by the signaling theory. Halal perception has association with respondents’ purchase decision. Thus, it highlights that halal perception is the mediating variable that intervenes in the relationship of a few independent variables and the purchase decision trends. The independent variables such as manufacturer identity, product label, physical product and packaging as well country of origin are considered to be important extrinsic cues that deliver messages regarding the halal of certain food products. The association of the four variables with halal perception is also found to be significant.
Originality/value
The originality of this study lies in its attempt to explore the role of halal perception in the marketing of food products especially within the scope of a Muslim’s market. Besides, this study attempts to investigate the halal issue based on a specific model that includes potential variables and the intervening role of halal perception.

Abstract
Purpose
Creativity is the core of digital knowledge-based economic growth and competitiveness. Given the fact that public service is a major contributor to the country's governance system, creativity among civil servants should be enhanced. Effective leadership in public services is necessary to nurture the creativity of high-quality public services. This study aims to examine the effects of transformational leadership on civil servant's creativity.
Design/methodology/approach
This study was conducted in six selected public service agencies. A total of 214 questionnaires were distributed to civil servant offices, only 82.2 percent (176 questionnaires) were returned. Data were tested using SMART PLS to determine whether the four transformational leadership dimensions, namely, intellectual stimulation, idealized influence, individual consideration, and inspirational motivation, exhibit a significant effect on creativity of civil servant officers.
Findings
Findings showed positive effects of the four transformational leadership dimensions on the civil servant's creativity.
Research limitations/implications
With small sample size, this study can still be expanded to all available public services sector in urban and rural area to gain a wider perspective.
Practical implications
This study presents strong managerial implications that can be used by public service to evaluate the consequence of transformational leadership on the creativity of employees, particularly the young civil servants. Through transformational leadership style, public service leaders can foster and improve young civil servants' creativity and share knowledge to achieve high performance.
Originality/value
With genuine verified measurement of transformative leadership and public sector creativity, the path correlation analysis shows that intellectual stimulation, idealized influence, individual consideration, and inspirational motivation have significant direct effects on creativity of the civil servant.

Abstract
Purpose
Different leadership styles are used to make innovations in organizations. So, a sound system of social exchanges has always been a need in this dynamic and technological world to challenge organizational problems. Drawing on the social exchange theory, this study aims to empirically investigate the mediating relationship of a set of social exchanges, e.g. leader-member exchange (L.M.X.), knowledge sharing behavior (K.S.B.) and voice behavior (V.B.), between transformational leadership (T.L) and innovative work behavior (I.W.B). Particularly, it explores the best social exchange behavior between T.L and I.W.B that plays a highly constructive role in the innovativeness of the hospitality industry in Pakistan.
Design/methodology/approach
The study targeted 403 frontline employees from hotels situated near Swat Valley, Pakistan. The study used a quantitative approach by using a convenient sampling technique. Structural equation modeling was run by using Smart partial least square 3.3.3 to test the proposed model.
Findings
The research supported that T.L significantly influenced I.W.B via a L.M.X., K.S.B. and V.B. T.L did not directly and significantly influence I.W.B so, there were full mediations between T.L and I.W.B. Specifically, knowledge-sharing behavior played a highly constructive role in innovativeness.
Research limitations/implications
The study targeted frontline employees from one place, Swat valley; however, data collection from different tourist places may generalize the results based on social exchanges and innovative behavior. A dyadic interaction between top-level and middle-level management may closely trace the innovative ideas among the employees.
Practical implications
The study found knowledge sharing to be a highly effective mechanism that supports employee innovation more than a L.M.X. and V.B. As a result, the managers should establish a sound system of knowledge sharing, which means a knowledge economy so that employees innovativeness can be boosted and promoted.
Originality/value
The present study was the first study in the hotel industry of Pakistan that reveals a highly effective mediating mechanism: K.S.B., which exists with T.L to increase workers’ innovativeness highly.

Abstract
Purpose
The purpose of this paper is to determine the factors that may influence customers’ acceptance of Islamic home financing and identify the possible moderator, which may be relevant using the decomposed theory of planned behaviour (DTPB) in the context of Malaysia and Pakistan.
Design/methodology/approach
Literature on Islamic mortgage and DTPB is reviewed in a bid to identify the determinants that may contribute to customers’ desire to participate in Islamic home financing.
Findings
The review indicates that customers’ acceptance of Islamic home financing is not only determined by the subjective norm, attitude, perceived behavioural control but also by the added construct of awareness and decomposed variables, namely, perceived compatibility, perceived relative advantage, peers influence and self-efficacy. In the context of the current study, the country is proposed as a moderator variable that may influence the relationship for customers’ acceptance of Islamic mortgages.
Research limitations/implications
In terms of conceptualising the model, only two countries are considered, which is Malaysia and Pakistan as categorical variables or moderators incorporated in DTPB.
Originality/value
Existing literature on Islamic mortgages makes it evident that DTPB is yet to be applied in the context of studying Islamic home financing. This study extends the application of DTPB in the context of customers’ acceptance of Islamic mortgages in two countries, Malaysia and Pakistan. This paper will be a helpful resource for future researchers, academicians and managers of Islamic banks at large.
