The wafer level package (WLP) is a cost‐effective solution for electronic packaging and has been increasingly applied in recent years. The purpose of this paper is to propose a newly developed packaging technology, based on the concepts of the WLP, the panel base package (PBP) technology, in order to further obtain the capability of signal fan‐out for fine‐pitched integrated circuits (ICc).

In the PBP, the filler material is selected to fill the trench around the chip and provide a smooth surface for the redistribution lines. Therefore, the solder bumps could be located on both the filler and the chip surface and the pitch of the chip side is fanned‐out. The design concept and the manufacturing process of the PBP would first be described in this study. The three‐dimensional finite element model is established based on the real testing sample and the thermo‐mechanical behavior of the PBP is simulated.

It is found that the solder joint reliability of the PBP can be highly improved because of the applied stress buffer layer. However, the accumulated stress/strain from the coefficient of thermal expansion mismatch may transfer to the metal lines in package. In order to enhance the robustness of the redistribution lines, the bypassed type interconnect is suggested. Moreover, the trace/pad connecting junction and the conductive via which have smooth outline are preferred to avoid stress concentration effects.

In this paper, a low‐cost and short time‐to‐market packaging technology is proposed which is especially suitable for high density IC devices. The PBP technology has the ability to meet the requirements of major reliability testing conditions and it will have a high potential for application in the near future.

To solve the problem of oil film thinning when hydrostatic thrust bearings are overloaded or rotating at high speed, the dynamic pressure formed by tiny oil wedges is used to compensate, and the optimum height of oil wedges is determined by the compensation rate to improve the bearing capacity of hydrostatic thrust bearings.

This research method is aimed at the new type of double rectangular cavity static bearing with microbevel surface of q1-205. The wedge parameters of oil film were defined. The oil film lubrication performance of the bearing with the wedge parameters of 0, 0.02, 0.04, 0.06, 0.08 and 0.10 mm was simulated by the finite volume method, the comprehensive influence law of the wedge-shaped parameters on the vorticity and flow rate of the oil cavity pressure fluid was revealed. Finally, the oil cavity pressure changes of oil films with different wedge parameters under certain load and speed were tested by design experiments, and the theoretical analysis and simulation were verified.

This study found that the oil film wedge shape can well compensate the static pressure loss caused by the high-speed or heavy-duty operation of the bearing, but the dynamic pressure effect of the wedge shape does not always increase with the increase of the wedge height. The oil film exhibits superior lubrication performance in the range of 0.06–0.08 mm.

The original hydrostatic oil pad was designed as a microinclined plane, and the dynamic pressure caused by the microwedge of the oil pad was used to compensate the static pressure loss of the bearing. The lubrication performance of the oil film under the condition of varying viscosity was obtained by using the simulation method.

The purpose of this paper is to examine young consumers’ general tendency to become confused and its effect on the word of mouth, trust, and consumer satisfaction in Indonesia – the largest smartphone market in Southeast Asia.

A combination of convenience and purposive sampling were used to select the sample of young adults in Daerah Istimewa Yogyakarta (DIY), Indonesia.

The results confirm that consumer confusion proneness comprises three dimensions; similarity confusion, overload confusion, and ambiguity confusion among young consumers in the smartphone market. Furthermore, each dimension has different consumer behavioural implications.

In the context of Indonesia and when targeting young consumers, companies should focus on defining unique product features instead of simply imitating competitor offerings, because similarity confusion negatively affects consumer trust. Moreover, managers should consistently emphasize unique and value-adding features to overload the product. This will lead to increased positive word of mouth, especially with the growing trend of social media usage among young consumers in Indonesia.

This paper represents a replication of Walsh and Mitchell's (2010) study. It is unique in that it is set in the context of the Indonesian smartphone market – the largest smartphone market in Southeast Asia, and concentrates specifically on the young consumer market. It provides valuable insights into the impact of consumer confusion proneness on the word of mouth, trust, and consumer across this age group and in this market.

The purpose of this paper is to investigate the effects of corporate dispersion on tax avoidance from geographical and institutional dispersion perspectives by using evidence from China.

Using a panel data of Chinese listed firms during 2003-2015, this paper estimates with correlation analysis and multiple regression analysis.

Both geographical and institutional dispersion are negatively associated with the degree of corporate tax avoidance. Furthermore, corporate governance mechanisms and female chief executive officers can mitigate the negative relation between corporate dispersion and tax avoidance. The results also indicate that ineffective internal control is one of the channels through which corporate dispersion reduces tax avoidance.

This is the first paper about the impact of firm dispersion on the degree of tax avoidance, complementing the research content of diversification and corporate decision-making.

This study aims to examine the relationship between an ownership structure with multiple large shareholders and corporate social responsibility (CSR) with regard to Chinese-listed companies.

Multiple regression analysis was used on 4,940 samples of 884 listed companies in China for the period 2009–2017, to empirically test the influence of an ownership structure on enterprises’ fulfillment of social responsibility. Moreover, the propensity score matching–difference in differences and Heckman two-stage approaches were used for the robustness of the regression results.

The results show that ownership structures with multiple large shareholders can promote social responsibility. The check-and-balance ability of non-controlling large shareholders, corporate information transparency and corporate system environment moderate the relationship between multiple large shareholders and CSR engagement.

This paper complements prior studies on the ownership structure of multiple large shareholders. The findings enrich the literature on corporate governance and CSR. The results also reveal information about the situational factors, helping identify the mechanism through which the ownership structure of multiple large shareholders affects CSR.

The goal of this paper is to investigate the relationship between government control and firm value in China.

Government might extract social or political benefits from a state-controlled firm, thus decreases firm value. However, government’s monitoring on firm management reduces managers’ agency problem, which increases firm value. We first build a game-theoretic model to prove the existence of optimal government control given these two roles of government, and we then employ the OLS regression method to test the theory predictions using the length of intermediate ownership chains connecting the listed state-owned enterprises to their ultimate controllers as the measure of government control.

We find that firm values first increase then decrease as government control weakens. Moreover, we find that government usually retains a stronger control over state-owned enterprises than the optimal level. In addition, we show that government control can be further weakened in firms with good corporate governance mechanisms, which serve as a substitution of government monitoring.

Our results demonstrate that government control in China is still a necessary but costly mechanism to mitigate agency costs, especially when corporate governance system is underdeveloped.

We identify the substitution effect between government control and corporate governance using a unique measure of government control.

The purpose of this paper is to study the effects of dimple geometries and arrangements on the heat transfer enhancement in a dimple jacketed heat exchanger.

For the purpose of this paper, with the experimental validated numerical model, this paper carries out numerical simulations of both single dimples with different geometries and the whole dimple jacketed heat exchanger with different dimple arrangements. For a single dimple, its secondary vortex flow, temperature differences and the pressure drop performance for different geometries are analyzed. For the whole dimple jacketed heat exchanger, the heat transfer and pressure drop performances are investigated by comparing the no dimple, triangular and rectangular dimple arrangements.

Results show that dimples can improve the heat transfer efficiency compared with conventional jacketed heat exchanger, and specific geometries and arrangement of dimples for better heat transfer performance are figured out.

This paper considers both dimple geometries and arrangements, which can be useful for further applications in specific integrated devices or similar applications.

The purpose of this paper is to illustrate and examine the effects of ultimate ownership, institutionality and their interactions on capital structure in a unified framework, based on evidence from China.

Using six years of panel data of Chinese non-financial listed firms between 2004 and 2009, this paper estimates with correlation analysis and multiple regression analysis.

This paper finds that debt financing facilitates the ultimate owner's expropriation behavior. The separation of control rights and cash flow rights is positively related to capital structure, while cash flow rights negatively affect it. Compared with private ultimate owners, state ultimate owners have less incentive to reap the benefits of expropriation, implying that the separation of control rights and cash flow rights has a smaller effect on the capital structure of state-owned firms. The improvement of institutionality can restrain ultimate owners' expropriation behavior, and regional institutional development is negatively related to capital structure. The separation of control rights and cash flow rights has a smaller positive effect on capital structure in regions with better-developed institutionality.

This paper incorporates ultimate ownership and institutionality into a unified analytical framework of capital structure. It not only enriches related studies on capital structure, but also helps us understand the institutional roots of irrational capital structure behaviors in China. This paper also provides further evidence on ultimate owners' expropriation of minority shareholders through debt financing.
