Drilling and routing are the only two conventional mechanical machining techniques used in the production of printed circuit boards. Unfortunately these operations are still often underestimated even though drilling, in particular, is just as important as the other processes involved in achieving the final quality of the finished board. The advantages and disadvantages of the various drilling techniques are discussed. This paper was originally presented at the First Printed Circuit World Convention held at the Cafe Royal, London in June, 1978.

The drilling and preparation of a hole in FR‐4 laminate prior to the deposition of electroless copper is considered in relation to the quality of soldering achieved on the finished printed circuit board. Data pertaining to the drill speed, drill feed, and stack position are presented and the effect of drilling temperature is demonstrated. The variability of laminate is discussed in relation to outgassing during soldering. Finally the importance of the post‐drilling treatment of the hole‐wall is shown. The relative effects of baking after drilling, ultrasonic cleaning and chemical treatments such as alkaline potassium permanganate are illustrated.

This study explores the phenomenon of company-specific plant role models. Following the establishment of distinct lead factories, recent studies imply that multinational companies are now using more detailed plant roles to manage manufacturing networks. While multiple plant role typologies can be found in literature, this is, to our knowledge, the first article to systematically analyze the content of such company-specific plant roles.

We rely on a multiple-case study design of 29 plant role models primarily belonging to multinational companies headquartered in German-speaking countries. Coding is performed to analyze the models for similarities and differences.

The content of company-specific plant role models seems highly dependent on a company’s context; hence, there is no one best way to build them. Companies appear to be pursuing different priorities with the application of plant roles, for example, the reorganization of manufacturing networks, the systematic allocation of products or the definition of decision-making autonomy. Compared to the primarily two-dimensional models from theory, companies rely on more dimensions to make their plant roles practical. Similar to models from literature, competence bandwidth, inter-plant knowledge/information flow and location advantage are the most relevant dimensions to differentiate plants from a headquarters’ perspective.

Plant role models are a powerful management tool that enables delayering the complexity and allows for proactive management of manufacturing networks. Managers fit the content of their plant role models to their company-specific context and the intended application for manufacturing networks. Managers aiming to build company-specific plant roles can use the conceptual framework based on the empirical findings as a benchmark.

This study complements prior research on plant roles by acknowledging that companies might develop their own version of plant role models rather than copying the ones from the literature. By doing so, we explore how plant roles look like in a real-world setting.

The purpose of this study is to investigate how soft lean practices moderate the performance effects of hard lean practices. The authors provide new evidence from the pharmaceutical industry, which is characterized by a highly regulated and technical environment and has been largely uncharted in the lean literature.

Based on a review of the literature, the authors define a set of soft and hard lean practices. The authors test the hypotheses using factor analysis and moderated hierarchical linear regression on a unique dataset containing survey data and real performance measures of 351 pharmaceutical plants.

The results show that soft lean practices can be both enabling and constraining. When management engages in performance measurement, visualisation and employee empowerment the relationship between hard lean practices and performance is positively moderated. On the other hand, when managers emphasise goal setting and work standardisation the performance outcomes are reduced.

Effective lean managers build organisational commitment by motivating other employees to implement lean. They use performance measurement, visualisation and employee empowerment to focus on the “why”. Less effective managers engage in commanding and micro-management. Such managers focus on the “what” by using practices like goal setting and work standardisation.

This article contributes to the literature on lean management by empirically testing the moderator-variable interaction effects between soft and hard lean practices. In addition, it adds new evidence from the important pharmaceutical industry.

The purpose of this study is to explore organizational enablers of frontline employees’ (FLEs) service-sales ambidexterity (SSA) in industrial firms expanding their digital service portfolios.

The authors conducted a qualitative study of five industrial firms pursuing digital service growth and, for this purpose, collected and analyzed interview data obtained from 50 service and sales managers and FLEs across three continents.

The authors identify and explain eight organizational enablers of digital service-sales ambidexterity (DSSA), operating at the macro, micro and meso levels.

Service and sales managers should use the identified organizational enablers to exploit the established service business and to explore new digital growth paths.

The study expands the prior understanding of SSA by advancing the concept of DSSA, unpacking its multilevel dynamics and operationalizing eight organizational enablers.

In this paper, the authors empirically investigate under which conditions production network management is effective to improve manufacturers' financial performance. For this, the authors explore contingencies between production networks and the three key dimensions of organizational environment.

A survey with senior managers was conducted for this research. The authors used a hierarchical regression analysis to test interaction effects and draw on follow-up interviews with chief operating officers (COOs) and senior managers to elaborate and explain the found associations.

Results indicate that manufacturers' financial performance is only associated with their network capability level if they operate in hostile competitive environments. In moderate competitive environments, improvements in the network capability level are not associated with greater financial performance. In particularly munificent environments, such production network upgrades are even associated with the opposite effect.

Results highlight in which organizational contexts upgrading production networks has positive performance implications and under which circumstances it is ineffective or even counterproductive.

The authors draw on unique survey data to add quantitative evidence to the predominantly conceptual and qualitative literature on global production networks. This is also one of the first studies to connect the topics of production networks and organizational environment.

Those most socially disadvantaged are at a greater risk of common mental disorder (CMD). The need to evaluate the health impact of social policy interventions that aim to reduce social inequalities between the disadvantaged and the better off is well recognised. This paper reports findings from a review to explore evidence on the health impact of UK policy interventions that aim to tackle the key social determinants of CMD. These were previously identified from the literature as cumulative socioeconomic deprivation, unemployment, psychosocial work characteristics, and poor social relationships. We identified some evidence of a positive impact on CMD of urban regeneration schemes, but evidence was sparse on interventions relating to the other determinants. The ability of research to inform policy designed to improve the lives of the disadvantaged could be assisted by a broader definition of what counts as evidence. This may include wider use of qualitative methodologies and a more deliberate focus on social processes known to be implicated in mental health.
