The purpose of this paper was to attempt to confirm the root cause of unstable stitch pull strength in PQFN package and propose some permanent solutions for it.

A screen experiment was designed to find the key process out of the manufacturing flow; a non‐destructive detaching method and cross section polishing were used to inspect the bond integrity; Auger analysis assisted with argon ion sputter was tried to confirm the contamination; finally the manufacturing processes were redesigned to prevent the contamination.

Some first aids of process optimization got little improvement; the screen experiment of processes found solder die bonding was the one resulted into a poor bond integrity which was demonstrated by non‐destructive detaching method and cross section inspection; Auger analysis assisted with argon ion sputter detected that there was a tin layer thicker than 20 nm coated on the bonding surface and the wire bondability of gold wire on this tin coating was poor; the lead frame was redesigned to prevent the wetting and flowing of tin and got a perfect performance.

Because of the limitation of time and resources, the proposed solutions for this issue could be studied more deeply.

This paper set up an example how to find out the root cause from the complex manufacturing process flow and put forward a quick solution accordingly for the issue.

Today, online malicious comments are serious issues. They can cause psychological distress and suicide of victims. Although prior studies have focused on the role of anonymity as a major factor in making these comments, results of these studies have been inconsistent. On the other hand, the need for attention from others can provide an alternative explanation for such malicious comments. However, this perspective has been rarely studied. Therefore, the objective of this study was to investigate effects of anonymity and need for attention on posting malicious comments online and compare these two factors, resolving dark sides of online interaction.

This study obtained 327 questionnaires of Facebook users through a survey and analyzed the research model using partial least squares (PLS) regression.

Results of this study revealed that the need for attention affected malicious comments through partial mediation of neutralization. On the other hand, anonymity did not significantly affect malicious comments.

This study has the following academic implications. First, we empirically examined the critical influence of need for attention on making malicious comments online based on the impression management theory. Second, this study revealed that the influence of need for attention on making malicious comments was partially mediated by neutralization. Third, this study may offer an explanation for contradicting findings on the role of anonymity in the phenomenon of posting malicious comments online.

Practical implications of this study are as follows. First, SNS platforms can limit activities of persons who post malicious comments frequently. Second, this study suggests that a notice is needed to inform the seriousness and harmful consequences of malicious comments. Third, Facebook practitioners should be aware that low anonymity may not reduce malicious comments.

This study quantitatively examined the effect of need for attention on malicious comments based on the impression management theory. It provides a fact that individuals who want to attract attention from others would write malicious comments through neutralization.

The purpose of this paper is to investigate the effect of reward redemption programs on donation amount, donation percentage and donation intention in the context of a bank credit card.

A 2 × 2 × 3 experiment is implemented with 1,070 consumers accessing a national US-based sample with a small compensation. The authors use general linear model to test the proposed hypotheses.

The findings show the main effects of reward types, limited-time message and value of reward redemptions on the percentage of donations and overall donation intention to charity. The type of reward (cash/points) is found to interact with the limited-time message and with the value of reward redemptions.

No prior studies have addressed the relationship between credit card redemption rewards and scarcity messages in the donation context. The study contributes to the understanding of the effectiveness of credit card redemption rewards with scarcity message in improving a consumer’s donation intention.

On a home game weekend of collegiate football, thousands of fan visitors spend their weekend participating in college football games, showing significant potential of sports tourism businesses in the USA. Understanding the original personality of sport tourists and their travel motivation factors is imperative to develop appealing tourist attractions at the destinations of sports team fandoms. The purpose of the study is to examine the relationships among tourists' personality characteristics, their push and pulls motivations, satisfaction with travel experience, and loyalty toward destination and team using structural equation modeling.

The author collected information from a total of 301 sports tourists who had traveled to a college football game within the past year, staying at least one night in a hotel or other lodging place. This study employed PASW Statistics 25.0 and structural equation modeling using LISREL 9.30 for data analyses.

Personality has a significant relationship with push factors, especially for socialization motivation, and pull factors (i.e. access and affordability, other attractions) had more significant effects on sports tourists' satisfaction than push factors. The findings indicate the key roles for the entertainment motivation in generating tourists' satisfaction and destination loyalty and important roles of destination loyalty in building team loyalty.

The present study provides an approach of sports tourists' travel behaviors and experiences in the sporting event tourism. The outcome of this research can help both sports event organizers and destination marketers to understand the motivations for sports game attendance and to develop marketing strategies and products/services for attracting various types of sports tourists to games.

Based on the resource-based view (RBV) and the signaling theory, this paper examines the effect of media reputation on financial performance as well as the moderating role of bank characteristics (risk management and financial capacities) in this relationship, using Vietnamese commercial bank data for the period 2007–2018.

We rely on the agenda-setting theory to measure the media reputation of banks. Return on average equity (ROE) is used as a proxy of financial performance. We regress financial performance on media reputation with fixed effects to control unobserved variables. In addition, the instrumental variable (IV) method is applied to deal with the endogeneity problem. We use the change in bank logo as an IV for media reputation.

We find that media reputation has a positive effect on financial performance. This effect becomes prominent for large banks, listed banks or banks that demonstrate good risk management capacities, and is particularly strong when we control for endogeneity bias. The effect of media reputation on financial performance is transmitted through the non-performing loan (NPL) channel.

The research findings further endorse the positive impact of media reputation on financial performance in the low-quality institutional settings. Moreover, these findings expand the existing knowledge regarding the relationship between media reputation and financial performance by affirming two strategies which could be used to leverage the contribution of media reputation including improving banks' risk management capacities and raising financial capital.

This is the first known paper to examine the effect of media reputation on financial performance in commercial banks in an underdeveloped institutional setting while exploring the moderators in this relationship. This study, therefore, provides insightful implications for different bank segments in managing NPL and taking advantage of media reputation as a potential resource of financial performance.

The exposure of concrete elements to high temperatures during fire can cause major risk to life safety and to the serviceability of a building. One of the main reasons for this is due to concrete spalling which caused by pore pressure and thermal stresses. Previous research has indicated that the inclusion of polypropylene fibres to concrete reduces explosive spalling. However, concrete containing polypropylene fibre can still be vulnerable to explosive spalling during fire. This paper presents the outcomes of a research investigating the effect of using steel fibres in addition to polypropylene fibres to reduce explosive spalling of concrete. The experimental part of this study evaluates the performance of six normal strength columns under a loading ratio = 60% of the design capacity and subjected to severe heating rate higher than ISO 834. The columns were cast using various dosages of steel and polypropylene fibres. Analyses of the main findings included evaluation of the measured concrete temperatures along with axial displacement recordings. The analysis demonstrates a clear assessment of the spalling levels of the various representative specimens. The study also compares the experimental axial displacement with theoretical predictions using DIANA. Conclusions drawn from the study indicate that adding steel fibresalong with polypropylene fibres can reduce the degree and severity of spalling if compared with concrete containing polypropylene fibres only. The spalling degree was reduced from 22.03% to 12.41% in best case and from 14.95% to 10.49% in average when steel fibres were used with polypropylene fibres.
