Abstract

Purpose

The purpose of this study is to develop a monolayer surface coating of stearic acid on Sn-Ag-Cu solder powder to limit oxidation.

Design/methodology/approach

Stearic acid was adsorbed onto Sn-Ag-Cu solder powder through liquid-phase adsorption. The isotherm of adsorption was measured and then the microstructure of coated powder was characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy.

Findings

The adsorption isotherm of stearic acid on the powder was “H” type, which revealed the layer-by-layer adsorption on non-porous surface. When the concentration of solution was in the range of 0.001-0.006 mol/L, with an adsorption amount of 0.12 ± 0.1 mg/g, monolayer stearic acid covered the solder powder completely. Uniform and integrated self-assembled monolayer coating was formed through hydrogen bonds between the oxygen ions in surface lattice of Sn3.0Ag0.5Cu solder powder and the —O—H hydroxyl group of stearic acid. The maximum angle of stability of coated powder also reduced by 2.87° compared with that of non-coated powder. The increase rate of oxygen content of coated powder was much slower than that of non-coated powder when they were exposed to humid air.

Originality/value

As a result, oxidation of fine solder powder was effectively limited. Essentially, this method can also be applied to the coating of other types of solder powder and has reference significance to other coating by liquid-phase method.

Abstract

Purpose

To explore substitutes for traditional Sn-Pb solder, Sn-20In-2.8Ag was considered because of its appropriate melting temperature, good reliability and high ductility at less than 100°C. However, the mechanical properties of Sn-20In-2.8Ag were not satisfactory. The reason for the poor mechanical properties of the Sn-20In-2.8Ag/Cu joint was revealed, and a way to solve the problem was found.

Design/methodology/approach

The microstructure evolution, characteristics of melting and solidification and joining performance with Cu were investigated using scanning electron microscopy (SEM), electron probe microanalysis, differential scanning calorimetry (DSC) and mechanical testing.

Findings

SEM results showed that the microstructure of Sn-20In-2.8Ag was composed of coarse dendritic Ag2In and γ phases, with Ag2In distributed at the grain boundaries. DSC measurements revealed that small amount of low temperature eutectic reaction, L → Ag2In + β + γ, occurred at 112.9°C. This reaction was caused by the segregation of indium, which is a process that has a strong driving force. In the lap-shear testing, a crack propagated along the grain boundary of the solder, and failure showed an intergranular fracture. This failure was connected with the three-phase eutectic and coarse Ag2In. Thus, to improve the mechanical properties, segregation of indium should be reduced and coarsening of Ag2In should be prevented.

Originality/value

The reason for the unsatisfactory mechanical properties of Sn-20In-2.8Ag was revealed via microstructural observations and solidification analysis, and the way to solve this problem was found.

Abstract

Purpose

For the basic problems on platform innovation, such as platform innovation connotation and characteristics, the driving mechanism and the influence mechanism are less been studied. This study aims to explore how to achieve platform innovation in traditional service enterprises.

Design/methodology/approach

Based on the theory of enterprise network and binary learning, respectively, this paper discusses the behavior of binary learning based on network structure and network impact on efficiency and innovative platform innovation, and analyzed the realization of the platform innovation path.

Findings

The research draws the following conclusions: the network structure-based exploitative learning can promote the efficiency platform innovation, while the network behavior-based exploratory learning can promote the novelty platform innovation. The interaction between network structure and network behavior embedded in traditional services is more conducive to exploratory learning so as to promote novelty platform innovation, and the platform innovation of traditional service enterprises is a process from efficiency-oriented to novelty-oriented. The innovation effect generated by exploratory learning based on network behavior is much higher than that generated by exploitative learning based on network structure. The theoretical contributions of this study are as follows: first, this study compares the similarities and differences between service innovation of platform-oriented enterprises and platform innovation of service enterprises. On this basis, it clearly defines the concept of platform innovation and divides it into two categories: efficiency platform innovation and novelty platform innovation. Second, it reveals the two paths for traditional service enterprises to realize platform innovation, and the interaction between these two paths are also explored, which promotes the scenario-based and dynamic study of platform innovation in traditional service enterprise. The conclusion of this study provides theoretical reference for traditional service enterprises to carry out platform innovation.

Originality/value

Theoretical contribution of this paper lies in: first, the concept of platform innovation is clearly defined. Current research about platform innovation is mainly around the innovation of platform enterprise and the platform innovation of traditional enterprise, but there is no document that makes clear distinction; some literature even equates innovation of platform enterprise with platform innovation of traditional enterprise. In this paper, through a detailed literature review and analysis, clearly define the concept of platform innovation and divided into efficiency platform innovation and novel platform innovation, which has made theoretical contribution to the depth of the research. Second, expand the platform innovation research of traditional service industry. In recent years, the platform innovation research of traditional enterprise has become a hot spot, but they focus on the attention of the platform transformation of traditional manufacturing industry, such as Haier; the traditional service industries seem to be “empty,” but, in fact, the traditional service industry platform innovation is of great significance and more worth looking forward to. In this paper, the longitudinal case studies can promote academic concerns focus on the traditional service industry, and also provides the theory instruction practice. Third, it promotes the platform innovation research of traditional enterprise and dynamic analysis. Based on the theory of enterprise network and binary learning, respectively, it discusses the behavior of binary learning based on network structure and network impact on efficiency and innovative platform innovation, and analyzed the realization of the platform innovation path. On the one hand, it enriches the research type of platform innovation; on the other hand, the dynamic evolution mechanism of platform innovation research can make up for the deficiency of the existing literature.

Abstract

Purpose

Degradation of repairable components may not be similar after each maintenance activity; thus, the classic (traditional-time based) maintenance policies, which consider preventive maintenance (PM), age-based maintenance and overhauls to be done at fixed time interval, may fail to monitor the exact condition of the component. Thus, a progressive maintenance policy (PMP) may be more appropriate for the industries that deal with large, complex and critical repairable systems (RS) such as aerospace industries, nuclear power plants, etc.

Design/methodology/approach

A progressive maintenance policy is developed, in which hard life, PM scheduled time and overhaul period of the system are revised after each service activity by adjusting PM interval and mean residual life (MRL) such that the risk of failure is not increased.

Findings

A comparative study is then carried out between the classic PM policy and developed PMP, and the improvement in availability, mean time between failures and reduction in maintenance cost is registered.

Originality/value

The proposed PMP takes care of the equipment degradation more efficiently than any other existing maintenance policies and is also flexible in its application as the policy can be continuously amended as per the failure profile of the equipment. Similar maintenance policies assuming lifetime distributions are available in the literature, but to ascertain that the proposed PMP is more suitable and applicable to the industries, this paper uses Kijima-based imperfect maintenance models. The proposed PMP is demonstrated through a real-time data set example.

Abstract

Purpose

This study aims to examine what types of interfirm linkages a firm enters in relation to its manufacturing strategy. The authors further aim to determine whether heterogeneous resources have different moderating effects on the relationship between a firm’s manufacturing strategy and interfirm linkages.

Design/methodology/approach

The sample consists of survey and archival data on 80 publicly listed electronics firms from the semiconductor and optoelectronics industries in Taiwan. Because the dependent variable, interfirm linkage, is a binary term, the authors apply logistic regression in our study.

Findings

This paper provides empirical insight into how a firm’s manufacturing strategy affects its probability to engage in specific types of interfirm linkages. The authors find that when a firm pursues an efficiency (flexibility) strategy, it will tend to engage in marketing (technical) interfirm linkages. In addition, absorbed slack strengthens the fit between manufacturing strategy and interfirm linkage type more than unabsorbed slack does.

Research limitations/implications

Because the sample is drawn from the Taiwanese semiconductor and optoelectronic industries, the authors encourage scholars to examine the generalizability of the findings. Future studies can furthermore adopt in-depth interviews to facilitate a better understanding of decision-makers’ considerations when entering interfirm linkages.

Originality/value

This study extends resource dependence theory across a firm’s boundary and applies the resource-based view to resource heterogeneity. The findings advance the understanding of the relationships between strategic orientation, slack resources and interfirm linkage choices. The authors show that it is important that firms consider strategic fit when they create linkages outside their existing boundaries.

Abstract

Purpose

This study aims to examine the phenomenon of the risk–return paradox from the resources side of the firm. The authors emphasize the moderating role of risk-taking capabilities in investigating the relationship between risk-taking and performance.

Design/methodology/approach

Building on the disciplines of the resource-based view, the moderating effects of risk-taking capabilities on performance were tested by using Taiwan listed companies' data from information technology and electronics industries. Based on the data from 216 firms for periods from 2003 to 2007, this study runs a hierarchical moderated regression analysis to test the hypotheses in the context of diversification.

Findings

The results of this study emphasize that risk-taking and its relationship with performance are context-specific. Significantly, it is contingent on the firm's risk-taking capabilities endowment. The findings also indicate that some aspects of risk-taking capabilities moderate the relationship between risk-taking and performance.

Originality/value

This paper emphasizes that risk-taking capability is an essential factor in investigating the risk–return paradox. It constructs the dimensions of risk-taking capability in terms of absorptive capacity, network resources and organizational slack. Firms equipped with a high level of risk-taking capabilities benefit from risk-taking activities and should, therefore, embrace risk.

Abstract

The kindergarten curriculum in mainland China has evolved through four periods and the current reform began in the end of 1980s. The reform aimed to transform kindergarten practice by shaping ideologies including respect for individual child, active learning, and play-based integrated curriculum. This review of research literatures shows that compared with the practice before the reform, many kindergarten teachers organize classrooms in learning centers, provide more play materials, pay time, and freedom for free play, and pay more attention to individuals. But indoor space organized in rice-seedling-bed model, teacher-led group instruction and teacher-controlled interactions are still often observed after three decades of reform efforts; there still exist great variations among kindergartens of different sponsoring bodies and in different regions. The problems resulted from the innate deficiencies of the top-down and value-priority reform, the conflicts between the advocated value and the traditional Chinese culture with emphasis on Ming-Fen, testing, and the value of children for the whole family and nation, and the unequal distribution of public resources decided by the educational institutions. Therefore, the curriculum reform is not a separate endeavor from other social changes, but a comprehensive and systematic change. To guarantee the success of the curriculum reform, the Chinese society needs cultural transformation and institutional reconstruction.

Abstract

Purpose

The purpose of this paper is to develop an evaluation model to determine the relative weights of key factors influencing international market development (IMD) success through analysis network process (ANP) during group decision-making. An empirical case of the Taiwan bulk shipping industry is used to illustrate the feasibility of the proposed approach.

Design/methodology/approach

The literature review is performed to generate 20 key success factors (KSFs) along with four factor categories in IMD (such as organizational capability, environmental scanning, international strategy and internationalization behavior). Then, ANP is applied to develop an evaluation model that prioritizes the relative importance linking the above four factor categories with 20 evaluated KSFs.

Findings

With respect to the final weights for factor categories, “international strategy” and “environmental scanning” are the two most important criteria, followed by “organizational capability” and “internationalization behavior”. The results also showed that by reviewing the global weights of the 20 KSFs of IMD, “service as competitive advantage”, “market potential” and “risk taking” have the highest rankings.

Practical implications

The findings indicate that firm expansion into international markets typically depends on a successful international strategy. Hence, to enhance their global market competitiveness, Taiwan bulk shipping firms should focus their efforts on planning international market entry strategy and prioritizing shipping services with high-potential target markets.

Originality/value

Theoretically, the study results can provide both theoretical basis and empirical evidence, indicating the relative weights and priorities of KSFs of IMD for the Taiwan bulk shipping industry. From the managerial perspective, the analytical results can help managers focus on main factors and identify the best policy to improve their IMD practice and performance.

The purpose of this study is to provide evidence on the impact of network flexibility and its ambidextrous influence on a firm's exploratory and exploitative partnership selection.

Abstract

Purpose

The purpose of this study is to provide evidence on the impact of network flexibility and its ambidextrous influence on a firm's exploratory and exploitative partnership selection.

Design/methodology/approach

The authors develop our hypotheses based on the literature of network flexibility and draw on a sample of publicly listed firms in Taiwan semiconductor and optoelectronics industries. The authors collect our data from survey questionnaires and archival sources and examine our hypotheses by using the generalized linear model (GLM) approach.

Findings

The authors’ empirical findings show that configuration flexibility has a greater influence on exploratory partnerships, while manufacturing flexibility has a greater impact on exploitative partnerships. In addition, when firms are ambidextrous (i.e. have both types of flexibility), they are able to simultaneously obtain both exploratory and exploitative partnerships. The authors’ findings indicate that balancing network flexibility is critical when firms execute ambidextrous alliance strategies.

Research limitations/implications

The authors’ use of survey data to measure network flexibility may limit our observations related to network evolution. In addition, the authors’ use of public annual reports to capture firm partnerships may cause us to ignore informal relationships between partners.

Practical implications

The authors’ empirical findings suggest that the types of partnerships firms develop depend on which types of flexibility they possess. The results further suggest that decision makers have to find a way to develop a balanced strategy between network configuration and manufacturing flexibility when they would like to develop an ambidextrous alliance strategy.

Originality/value

The authors’ study advances the understanding in the literature on supply chain flexibility and its ambidexterity by connecting network flexibility and ambidextrous alliance strategy. The authors offer a guide to supply chain managers in the area of network design.
