Abstract
A major drawback of current copper thick‐film technology is the inefficient removal of the organic binder associated with the dielectric material in the low‐oxygen inert gas (N2) atmosphere of the furnace. In processing large area and/or multilayer substrates, the incomplete binder removal causes deleterious effects which have been well documented. Therefore, it is necessary to remove hydrocarbons and residual carbon from the films in the burn‐out section of the furnace before the films begin developing their characteristic microstructures. However, the atmosphere currently employed is not capable of removing all the carbon and hydrogen in the form of gaseous oxides. In literature, in addition to furnace modifications, several atmosphere modifications and manipulations have been proposed to achieve optimum properties for the fired films. With few exceptions, the scientific basis for such atmosphere modifications and manipulations has been left either unaddressed or obscure. With this background, this paper examines the feasibility of using a reactive gas mixture in the furnace to achieve efficient organic binder removal. Phase stability diagrams are presented to illustrate the stability of (i) carbon, (ii) thick film copper ingredients, (iii) active phases of resistors, and (iv) components of glassy and crystalline phases of dielectrics in selected reactive atmospheres. The stability of certain furnace belt constituents is also addressed. Mass balance calculations are shown to demonstrate the extent of carbon removal and copper oxidation in typical nitrogen atmospheres. Based on the interpretation of thermodynamic data and reaction mechanisms involved, a specific H2‐H2O mixture with nitrogen as the carrier gas is recommended. The approach presented here constitutes a general analytical scheme to understand materials‐atmosphere interactions occurring across a temperature range. Several issues in furnace design are also discussed from the standpoint of gas‐solid reaction kinetics. These deal with the design of gas‐flow systems that facilitate removal of organic binders.

Abstract
This paper reports the results of development work conducted on nitrogen‐based atmospheres in order to improve the firing of copper thick film systems through continuous furnaces. The proposed solution is particularly suitable for industrial production conditions since it allows variations of the material quantity processed per unit time, resulting not only in an improvement in quality but also in productivity. Such improvements have been achieved by using a new gas distribution system which provides both zone control and regulation of oxygen additions in the nitrogen furnace atmosphere. An efficient set‐up of this system has become possible thanks to precise control of the oxygen profile in relation to the temperature cycle, taking into account various inks' characterisation, and owing to an extensive study of the effects of oxygen additions on copper thick film properties. The solution was tested in a muffle‐lined belt furnace with several commercial dielectric and copper inks, and for increasing oxygen additions into the furnace preheat zone. Different sample patterns were designed to test both monolayer and multilayer systems. The test programme includes measurements of resistivity, bondability, solderability, dielectric breakdown voltage and adhesion of copper films on alumina and on dielectric layers before and after ageing. Ink characterisation by thermogravimetry and by several gas analyses has confirmed that the organic vehicle removal mechanism under nitrogen atmospheres doped with oxygen is a burnout. Indeed, significant oxygen consumption occurs within the temperature range of the removal, as a function of the amount of ink processed. Oxygen additions in the furnace burnout zone greatly improve both the dielectric breakdown voltage and the adhesion of copper on alumina and on dielectric (especially after ageing), while sheet resistivity, wire bondability and soft solderability are not altered below a defined O2 level. It is therefore possible to determine an optimum oxygen addition range for which the thick films fired under such conditions will have the best characteristics. This optimum oxygen window is achieved thanks to a new regulation system which operates whenever variations occur in the quantity of paste processed.

Abstract
Diffusion patterning is a dielectric patterning technology, which is used in the screen printed thick film technology for higher density multilayer circuits. This technology is suitable for producing lower cost multichip modules and requires a low additional investment in conventional thick film technology production lines. Comparisons of via resolution capability of diffusion patterning versus conventional thick film technology are described and discussed. Preliminary experimental results obtained with a test circuit showed that 200μm lines and 200μm vias could be achieved with acceptable yield and with minimal modification to standard production lines. The electronic circuit for the pressure sensor was designed and realised with the verified technology as a low‐cost ceramic multichip module. A few results of an investigation of some thick film materials, which comprise the “set” of pastes for diffusion patterning technology, are presented.

Abstract
Purpose
For this paper, the authors focus on Porter’s competitive advantage. Hybrid strategy refers to how a firm creates value vis-à-vis competitors by simultaneously relying on lower costs and greater differentiation to achieve a competitive advantage. This strategy emphasises both and aims to provide much more monetary value to customers through the combination of reduced cost and a higher rate of differentiation. In addition, this research focuses on family small and medium-sized enterprises (SMEs), because they have particularities arising from the incorporation of family members both as owners of the SME and in managerial positions. The porpose of this study is to analyse whether the existing differences produced by the role of the family in strategic decision-making and the concentration of family power have a higher impact on performance and innovation than non-family SMEs.
Design/methodology/approach
Structural equation modelling was used to analyse Spanish firms with fewer than 250 employees. This study randomly selected SMEs operating in Spain from the Spanish Central Business Directory (2021) database. The overall sample design was based on stratified sampling.
Findings
SMEs are facing new challenges, and this has led to the emergence of new competitive strategies. Companies have started to combine differentiation strategies with cost strategies to achieve superior performance and better adapt to these changes. This study confirms a positive relationship between the adoption of hybrid strategies and market performance in SMEs. In addition, hybrid strategy reinforces innovation, which has a mediating role between hybrid strategy and market performance. Finally, the findings indicate that family SMEs achieve a greater impact of hybrid strategy on innovation than non-family SMEs. Moreover, innovation plays a mediating role only in the case of family firms, which enhances the relationship between hybrid strategy and market performance.
Originality/value
For SMEs to survive in turbulent environments, this study proposes the adoption of hybrid strategies instead of pure strategies. The novel model links hybrid strategy (as opposed to “stuck in the middle”), innovation and market performance. The research is valuable for owners and managers of family SMEs because this study finds differences in the relationships studied compared to non-family SMEs.

Abstract
The Benelux chapter has made a habit of organising meetings with a scientific and commercial accent more or less alternately. This approach has proven to be successful in the past three years. The 1986 Autumn meeting will be another display meeting. A number of papers will be presented by suppliers of materials and equipment for the hybrid and surface mounting industry. In a 300 m2 exhibition room about 25 companies will display their products. The programme of the day leaves ample opportunity for meeting colleagues and suppliers. The meeting will be held in the ‘Jaarbeurs Vergadercentrum’ in Utrecht on 16 October from 9.30–17.00. The annual ISHM‐Benelux general membership meeting will precede the lectures.

Abstract
Organizational research on diversity, equity, and inclusion (DEI) is at times siloed; the experience of one minoritized or underrepresented group is treated as completely separate and different from the experience of another group and thus research separately. For example, there are terms that are studied only in the context of one group, and a different term is used to study a very similar (or identical) concept among a different group. Indeed, there are many unique experiences that specific minority groups encounter at work. Because of this end, minority groups should not be fully categorized together, and their individual should not be erased. However, there are shared experiences that many or all minorities experience at work, whether they are a gender minority, racial minority, or a member of any other minoritized group. Recognizing these shared experiences can help scholars develop a deeper understanding of what it's like to be minoritized or underrepresented at work, and therefore help to better serve these communities. To this end, our chapter highlights three such shared but unique minority experiences: three experiences that are common across all minority groups but operationalize slightly differently in different populations. The first experience we discuss is discrimination, as all minorities typically experience some form of negative differential treatment at work. The second experience we discuss is identity management, as many minorities need to actively think about how they present their minority identity to others (regardless of if their identity is “concealable” or not). Finally, we discuss strength through adversity, as many minorities argue that their minority identity is a source of strength and an area that benefits them at work. We conclude the chapter with a call toward intraminority solidarity, suggesting that recognizing shared experiences and working together can help build better workplaces for all minority employees.

Abstract
Purpose
The purpose of this paper is to focus on how corporate social responsibility (CSR) (i.e. responsibility to customers, employees and society) influences customer behavioural loyalty in the hotel industry. The mediating effects of brand image and customer trust on the relationship between CSR and customer behavioural loyalty are also considered.
Design/methodology/approach
In total, 298 valid responses to questionnaire surveys were collected from a convenience sample in China in 2017. A structural equation model was used to test the hypotheses.
Findings
Hotel customer behavioural loyalty can be enhanced by CSR performance. Performance in each of the three CSR domains positively impacted customer behavioural loyalty to different degrees. The impact of CSR on the customer had the strongest influence on Chinese customers’ behavioural loyalty among the three CSR domains of customer, employee and society. Brand image and customer trust were found to be mediators of the relationship between CSR performance and customer behavioural loyalty.
Originality/value
The current research contributes to the literature by demonstrating that CSR activities are not all equally effective. Results reveal that the society dimension of CSR had the strongest impact on Chinese customers’ brand image of hotels among the three CSR dimensions investigated. In terms of Chinese hotel customers’ trust, the CSR–customer dimension plays the most effective role. The findings also support the notion that Chinese consumers are beginning to use CSR information to evaluate hotels.

Abstract
This literature review provides an overview of previous research on attention-deficit/hyperactivity disorder (ADHD) and entrepreneurship. After introducing the relevance of the topic and discussing different perspectives on ADHD and entrepreneurship, this chapter reviews 26 academic journal publications. In the first step, it reports how authors of empirical studies have measured ADHD and reveals a dominance of quantitative research designs. In the second step, it presents insights from previous research on ADHD and the likelihood of becoming an entrepreneur, the relationship between ADHD and entrepreneurial intentions or preferences, the translation of entrepreneurial preferences into entrepreneurial actions, and finally, ADHD and entrepreneurial performance. The literature review finds that previous research has not yet provided conclusive results on the relations between ADHD and entrepreneurship. In the third step, therefore, this chapter outlines avenues for further research.

Abstract
Purpose
This study aims to examine the role of the dimensions of entrepreneurial orientation (EO) under turbulent market conditions and reveal the role of an entrepreneur's perception of a crisis in shaping the impact of EO on firm performance.
Design/methodology/approach
This study uses partial least squares structural equation modeling (PLS-SEM), multiple linear regression (MLR) and fuzzy-set qualitative comparative analysis (fsQCA). The study sample was comprised of 117 one- and two-star hotels that were operating in Poland.
Findings
The results showed that proactiveness and risk-taking significantly affected firm performance. Furthermore, the results revealed that an entrepreneur's perception of a crisis moderated the impact of risk-taking and proactiveness on firm performance. In particular, the findings suggested that, in firms where the crisis strongly influenced their operations, performance was affected by proactiveness, while in those firms where the crisis influenced their operations to a low or moderate degree, performance was affected by risk-taking. Furthermore, fsQCA unveiled the role of innovativeness, which (along with risk-taking) is a sufficient condition that leads to firm performance.
Originality/value
Two characteristics make this study original: first, it investigates EO under turbulent market conditions, and second, it analyzes the role of an entrepreneur's perception of crisis consequences for business operations. The study contributes to the literature on entrepreneurship and crisis management with findings on the different roles of EO dimensions under crisis conditions and an observation about the moderating role of an entrepreneur's perception of the impact of a crisis on operational management and how this perception differentiates the impact of risk-taking and proactiveness on firm performance.
