Abstract

A new corrosion test for assessing flux residues is applied to marginally cleaned water soluble fluxed test boards and low solids/no clean fluxed test boards. This test method developed by Bono has been modified to accelerate the corrosion process. The corrosion mechanism observed in this study is conductive anodic filament (CAF), a corrosion mechanism proposed in 1979 by Lando et al. It is postulated that this degradation mechanism is due to the high bias voltage (190 V) coupled with the high humidity (85%) and high temperature (85°C) conditions used in this test. Important parameters in the test method are discussed and recommended refinements are given.

Abstract

OUR good custom, as we deem it, to wish our readers a larger measure of happiness and success than heretofore we repeat for 1947. There are many signs in the libraries to give encouragement to the hope that they, the libraries, are now so well established everywhere that the old evils of complete disregard, penury and restriction will not recur and that, gradually but surely, the aims and the purpose for which we stand will be realized. That they may be so for all readers of The Library World is, we believe, the best possible New Year wish.

Abstract

Purpose

Modern working life is characterized by increased expectations for employees to be available to deal with work issues outside regular work hours and by using new communication technology. This implies more individual freedom in organizing work in time and space, but also places increased demands on employees to manage the boundaries between work and personal life. This, in turn, can be expected to be crucial to their ability to mentally detach from work during free time. The purpose of this paper is to investigate whether individual perceptions of boundary control moderate the impact of after-hours availability expectations and work-related smartphone use during off-work hours on psychological detachment.

Design/methodology/approach

The study population comprised 2,876 gainfully employed professionals from four large organizations in both the public and private sector, representing various businesses and occupations. Univariate correlations and multiple, linear hierarchical multiple regression analyses were performed.

Findings

High after-hours availability expectations, high frequency of work-related smartphone use, and low boundary control were associated with poor psychological detachment. Furthermore, boundary control moderated the relationships between both after-hours availability expectations and work-related smartphone use, respectively, and psychological detachment. As such, boundary control mitigated the negative effects of both after-hours availability expectations and work-related smartphone use during leisure on psychological detachment.

Practical implications

Modern work organizations would benefit from introducing availability policies and helping employees reduce their work-related smartphone use outside regular work hours, thus helping them achieve successful boundary control and subsequent psychological detachment.

Originality/value

In a working life characterized by blurred boundaries, employees’ ability to achieve boundary control can be regarded as crucial.

Abstract

Today's emphasis on alternative flux technology as an approach to eliminate the use of chlorofluorocarbons (CFCs) requires an understanding of the corrosion potential of the new fluxes. In 1989, Dr David Bono proposed that monitoring the effect of different soldering fluxes on the rate of corrosion of a copper wire printed on a circuit board would provide quantitative information on the corrosion potential of a flux. Further analysis of this testby Turbini et al. revealed that the degradation mechanism associated with Bono's test is the growth of conductive anodic filaments along the glass fibres of the epoxy‐glass boards. The original test method has been revised, and the test coupon redesigned with the goal of developing a standard, quantitative test method to characterise soldering fluxes. This paper will describe the equipment, test coupon and electrical circuitry associated with this proposed test method. Procedures chosen to reduce error sources associated with electrical noise will be reported and explained.

Abstract

Purpose

The purpose of this paper is to investigate the extent to which the influence of professional commitment on intention to leave a profession is contingent on the combined effect of job search and sportsmanship.

Design/methodology/approach

The research is based on a sample of professional employees (N = 327). Moderated moderation was the approach used for testing the hypotheses.

Findings

Findings showed that the moderating effect of job search on the relationship between professional commitment and intention to leave a profession is higher at a low level of sportsmanship and lower when sportsmanship is high.

Originality/value

The research indicates that job search does not necessarily constitute a sign of acceleration of intention to leave one’s profession. In the case of professionals expressing a high level of sportsmanship, job search appears more like a precaution.

Abstract

Under certain environmental conditions, printed wiring boards (PWBs) respond to applied voltages by developing sub‐surface deposits of copper salts extending from anode to cathode along separated fibre/epoxy interfaces. These deposits are termed conductive anodic filaments (CAFs) and, in this work, the dimensions and growth patterns of a CAF have been determined by serial sectioning. The CAF growth pathway is characterised and the spatial distribution of the copper salts is quantified with scanning electron microscopy (SEM) using backscattered electrons. The chemical composition of the CAF is determined using energy dispersive X‐ray analysis (EDS). Prior research using high‐resolution non‐destructive X‐ray microtomography is correlated with the serial sectioning data. The failure phenomenon known as CAF may pose serious long‐term reliability concerns in electronics applications exposed to adverse and hostile environments.

Abstract

The corrosive power of solder pastes is studied by implementing a new method compatible with the common rules of use. The entire methodology is fully described. The results show evidence of corrosion with some solder pastes that have been identified by microscopic and EDX analysis. The corrosion mechanism is ‘mouse bite’ and conductive anodic filaments. A ranking of the different solder pastes tested is given and pass criteria for this new method of evaluation are proposed.

Abstract

Purpose

The information and communication technologies have made it progressively practical for employees to remain associated with work, even when they are not in the workplace. However, prior studies have provided very little understanding of the implications for the deviant behavior aspect. The current study aims to investigate the association between after-hours work-related technology usage and interpersonal, organizational and nonwork deviance through psychological transition, interruption overload and task closure. The authors draw upon the theory of conservation of resource (COR) to examine the research model.

Design/methodology/approach

The primary data for the study has been collected in two waves from the sample of 318 employees who were working in diverse organizations in the Anhui province of the People's Republic of China for empirical testing of the authors’ research model.

Findings

This study's findings have revealed the positive association of after-hour work-related technology use with individuals' deviance in its entire three forms through psychological transition and interruption overload and have negative associations with all forms of deviance through task closure.

Originality/value

The significant contribution of this study is in the literature on technology use and employee outcomes, by identifying the consequences of technology use in both work (interpersonal deviance and organizational deviance) and outside work domain (nonwork deviance) and exploring the underlying mechanisms for these relationships in detail. To the best of the authors’ knowledge, this study is the first of its kind that investigates a relationship between after-hours technology use and all three kinds of deviance while exploring both the positive and negative perspectives in one study.

Abstract

Purpose

This study aims to examine the moderating effects of psychological entitlement and perceived organizational support (POS) on the relationship between work connectivity behavior after-hours (WCBA) and job satisfaction.

Design/methodology/approach

Data were collected from 217 full-time employees of an Internet company in China at two points in time separated by about one month. Hierarchical regression and simple slope analyses were conducted to test hypotheses.

Findings

The results showed that WCBA was negatively related to job satisfaction and that this relationship could be mitigated by POS. Moreover, psychological entitlement aggravated this relationship, and this aggravating effect was stronger when POS was at low levels.

Practical implications

Managers should avoid intervening employees' nonwork domains too much. If this is unavoidable, managers should provide adequate organizational support to help employees cope with the challenges brought by WCBA. Besides, managers need to pay close attention to highly entitled employees and take measures to modify their expectations.

Originality/value

First, this study enriches the understanding of what WCBA is and how WCBA works by investigating the influencing mechanism of WCBA from the perspectives of effort–reward imbalance and job demands–resources. Second, by verifying the moderating effects of psychological entitlement and POS, this study provides insights into the boundaries of the WCBA–job satisfaction relationship. Third, this study contributes to the literature on psychological entitlement by identifying its one applicable condition.
