The purpose of this paper is to investigate oxidation and the Au‐Sn reaction of laser reflowed (LR) micro‐solder joints when different protective atmospheres were applied.

A N2 atmosphere at room temperature, 60°C, 100°C and 130°C, or an air atmosphere at room temperature were utilized in this study. The solder balls were composed of Sn‐2.0Ag‐0.75Cu‐3.0Bi, and 120 μm in diameter. The surface finish of one pad of the joints was 4.0 μm Au/0.1 μm NiFe/0.01 μm Ta, another pad was made of Cu plated with 3.0 μm Au. The laser reflow process time was controlled to within 10 ms. Auger Electron Spectroscopy (AES) was used to identify the oxidation condition of LR solder joints with or without protection from a N2 atmosphere at room temperature. The appearance and cross‐sections of the joints protected by a N2 atmosphere at different temperatures were evaluated using SEM analysis.

Oxidation of LR solder joints from an air atmosphere was extremely severe, and the surfaces of solder were rough as compared with joints protected by a N2 atmosphere. Au‐rich phases and needle‐like AuSn4 intermetallic compounds (IMCs) formed at the interfaces of the solder and the pads. As the temperature of the N2 atmosphere was increased above 100°C, almost all of the Au‐rich phases disappeared. More needle‐like AuSn4 IMCs formed at the interfaces, as compared with that in joints protected by a N2 atmosphere at room temperature and 60°C. In addition, the orientation of the IMCs had clearly changed.

The results may provide a guide for controlling oxidation and the Au‐Sn reaction of micro‐solder joints during the LR process, and improving the properties of joints between solder and pads with Au surface finishes, by regulating the protective atmosphere.

The atmospheric turn can be understood as a departure from the occidental dominant thing and event ontologies and opens the way to a situation ontology, in which subjective-bodily felt being-in is at the centre. The focus shifts from objective things or events to subjectively experienceable facts of being within situations and atmospheres. Atmospheres have an affective content, a peculiar non-dimensional spatiality and a hybrid status beyond the typical occidental dualisms, such as subject and object or inner and outer world. If the philosophical potential of the atmospheric turn is highlighted and taken seriously, then fundamental new perspectives in thought and action can reveal themselves.

This contribution deals with the effects of atmospheres. It considers the interest in atmospheres as part of a fundamental change in the mode of individual reasoning which is characterised in contemporary post-industrial societies by an ‘experience orientation’. Atmospheres, which highlight the fact that the subjective state of a person can change in relation to the sensory qualities of the environment, become an interesting concept within this development. The chapter starts from the observation that – in spite of the importance that atmospheres have for spaces of leisure and tourism – there is little research on atmospheres in leisure and tourism studies. It presents three dimensions of effects of atmospheres (emotions and affective tonalities, attention, gesture) that allow us to understand why and how atmospheres matter. The second part links the effects of atmospheres to leisure and tourism, where it proposes distinguishing the corporeal and the sociocultural dimensions of atmospheres. Finally, it discusses the possibilities of designing atmospheres and stresses the necessity for further empirical research.

The rhythmic patterns of urban mobilities, and their fluctuations and modifications across the day, give the streets their perceived and experienced atmosphere and character. This paper examines such street atmospheres and focusses on the role of embodied mobility rhythms in the (re)making of the atmospheres throughout the day. Utilising a rhythmanalytical framework and research data comprising videoed site observations and on-site fieldnotes, the study analyses ‘crepuscular’ (behaviour taking place during the twilight hours of the day, at dawn and dusk) mobility rhythms that reveal internal tensions and modalities of urban sites across a 24-hour period. The analysis highlights the connections between fluctuating pressures of motor traffic and mobile embodied appropriations of the space in the making of the streetscape and its changing atmospheres between the ‘day-time city’ and the ‘night-time city’. The chapter demonstrates that an analytical focus on such ‘in-between’ temporalities of the twilight can help to map the complex and multifaceted urban polyrhythmia, which, in turn, might provide new insight for rhythm-based perspectives towards urban atmospheres and street spaces as sites of urban social life.

This introduction to the volume Atmospheric Turn in Culture and Tourism: Place, Design and Process Impacts on Customer Behaviour, Marketing and Branding (Emerald) positions the atmospheric turn in the context of recent paradigmatic turns such as the linguistic turn, iconic turn, cultural turn, spatial turn, mobility turn and design turn. The specific contribution of the atmospheric turn is its profoundly holistic interest in overarching connections which are perceived with all senses and include both matter and idea. With its 22 chapters, this volume sets out to sharpen the atmospheric gaze and perception in research and beyond.

First, this chapter traces how the concept of atmosphere has evolved in the fields of theology, philosophy, geography, sociology, psychology and architecture. Then it analyses the question of how to describe atmospheres and how to deepen the perception of atmospheres through market research. Finally, the chapter discusses the possibilities and limits of naming and typologising atmospheres.

This chapter proposes a place atmosphere model, which can be used for all types of space, from the landscape to the municipality to the property. In addition to the emotional aspects, this atmosphere model also describes the socio-cultural, economic and ecologic dimensions that can shape an atmosphere. It is modelled in such a way to permit connecting to the theory and practice of brand and destination management in particular and to the model and process ideas of the planning, design and construction industries.

Comparing two different descriptions of the atmosphere of one and the same city allows for interesting insights regarding the production, duration and perception of urban atmospheres. Aspects of time are very important in this context as they form typical atmospheres here and always, ensure that the patina of the city and the people is based on experience, and generate expectations prior to actually felt-bodily perceptions by means of narration. Changes in environmental qualities or modes of perception can provide clues to both typologies of places and the people present. Moreover, this chapter introduces the Atmospheric Portfolio, which illustrates how research on personal atmospheric perception as well as site-specific atmospheres of a location becomes possible. In the sense of further heuristic starting points, methods employed by other research projects will supplement the study.

This study aims to explore aesthetic atmospheres and their affordances in urban squares to advance knowledge on the research and design of attractive living environments.

Descriptions of pleasant and unpleasant experiences of urban squares were collected using qualitative questionnaires with open-ended questions. The theoretical framework and the lens of aesthetic affordances were applied to pinpoint and understand the connections between the place attributes and experiences.

This study found four distinct aesthetic atmospheres formed by perceived synergies of both the material and immaterial aspects of the environment. It was also found that the atmospheres may shift. A model that shows the aesthetic atmospheres and their potential affordances as layered and emerging is presented.

Everyday aesthetics considered as affordances open new research perspectives for the understanding of what generates attractive living environments – or not.

Aesthetics affordances may provide the design professionals and alike means on how to design places that engender specific aesthetic atmosphere.

Gathering and discussing commonplace aesthetic experiences in everyday life may enhance democratic participation in place development among people with different levels of design expertise.

This study combines theories of place with a novel concept of aesthetic affordances to identify distinct aesthetic atmospheres. A holistic overview structure of how the various constituents of aesthetic atmospheres relate to each other provides new ways of studying and understanding urban aesthetic atmospheres.

This study explores whether religion plays an important role in corporate poverty alleviation. Religious atmosphere affects managers' attitude towards corporate social responsibility (CSR) and then influences corporate poverty alleviation. This study first examines the impact of religious atmosphere on corporate poverty alleviation and then investigates whether formal institutions, such as law enforcement environments and ownership, influence the relationship between religious atmosphere and corporate poverty alleviation behavior.

In 2016, the Chinese government initiated a nationwide campaign aiming to eliminate poverty in China by 2020. The authors conduct empirical tests with data on Chinese listed firms from 2016 to 2020. The religious atmosphere is measured by the number of Buddhist monasteries and Taoist temples within a certain radius around Chinese listed firms' registered addresses. The authors adopt the ordinary least squares (OLS) method for regression and take the two-stage least squares (2SLS) method to address the endogeneity issue.

The results show a positive relationship between religious atmosphere and corporate poverty alleviation donations. Law enforcement attenuates the positive association between the religious atmosphere and corporate poverty alleviation donations. Religion and corporate poverty alleviation donations have a more positive association for non-state-owned enterprises (non-SOEs) than for state-owned enterprises (SOEs).

The authors' findings have important implications. First, this study inspires incorporating the ethical value of traditional culture, such as religion, into CSR. Second, the findings imply that informal institutions have a greater impact on corporate decision-making when formal institutions are weak, suggesting that informal institutions should be emphasized when promoting CSR in countries where formal institutions are relatively weak. The study investigates only religious influence on corporate poverty alleviation based on Buddhism and Taoism, but the authors do not examine the impacts of other religions. Future research may examine the relationships between other religions and corporate poverty alleviation in China.

This study illustrates the positive role played by religion in promoting CSR by relating religious atmosphere to corporate poverty alleviation. It fills the research gap between religion and CSR and also contributes to the literature on determinants of corporate poverty alleviation.
