As the modern world evolves through innovation and technology, manufacturing companies of semiconductor drive their people to dedicate themselves on continuous improvement and technical advancement. Products they produce becomes smaller and thinner, but applications are limitless and innovative. In manufacturing of quad flat no lead packages, challenges were encountered during the die attach process especially in small die size. Die attach material overflow on pad is one of these, and certain parameters and techniques are explored to have a quality and robust process. Defining appropriate epoxy pattern with respect to the die size is a big factor to make sure no epoxy material will flow outside the die pad perimeter that may cause unit rejection. This paper will discuss the related issues of the said package by performing experiments and applying certain techniques to address the problem.

Glass material used on a semiconductor device for isolating currents are one of the new breakthroughs of the modern world. Challenges are inevitable due to its complex characteristics and unique appearance. The study focuses on the phenomenon of reject glass die unrecognized, picked and bonded by die attach machine on good units of the semiconductor quad-flat no-leads (QFN) device in focus. This QFN device utilizes glass die as interposer on two active dice that separates the dielectric current of each die. During die attach process, machine photo recognition system failed to recognize and detect the glass die reject marking due to its unique transparent design and will be attached on good units. Thus, resulting to gross rejection and low process yield. Practical solutions to prevent the said phenomenon are simulated and determined by performing selection of variables like the contrast of the reject mark related to the product structure and compatibility through statistical analysis. The improvement drives to promote process robustness and scrap reduction that will help the manufacturing to be competitive through innovative resolutions on problems.

Continuous improvement gained much attention in the literature as one of the principles in total quality management and practice under methodologies such as Lean or Six Sigma. Continuous improvement in organizations represents a comprehensive process that includes involvement of all people on all organizational levels to make improvements throughout the whole organization. Therefore, building and sustaining the organizational CI capability through practicing the CI behaviours leads to achieving better efficiency, effectiveness and business results of the organization. Also applying CI behaviours leads to change in organizational culture which is, in the long run, oriented toward making every day continuous improvements. The purpose of this paper is to present which CI behaviours can be developed in organization and measured according to the Bessant's evolutionary model of continuous improvement behaviour. Also, the goal of the research is to present based on the conducted research, the state of CI practice regarding adopted CI behaviours which will be presented as the development level of CI behaviours that researched manufacturing companies in Croatia with ISO 9001 certificate, have.

Multiple Case

This study examines the contribution of a pair of opposite factors: technology versus people, and innovation vs. continuous improvement to obtain manufacturing flexibility. These factors are opposing as they play different roles in TQM and BPR. An exploratory multiple case study was conducted that involves three Malaysian manufacturing companies from electronic and electric sector. The results show that flexibility could not be achieved through technology solely, but by combining technology with people, the required outcome is attainable. By applying innovation and continuous improvement simultaneously, it will yield better flexibility than if only one of them was used. The contribution of these factors in the selected manufacturing setting could guide practitioners to obtain flexibility and verify the research model that could be tested further in a survey.

Quality Function Deployment — QFD combined with Concurrent Engineering — CE as a support tool for the competitive strategy on product development is devised. In this study, beyond the proposed method, it is intended to develop relations with innovational models, arrangements of innovation and technology transfer, learning in organizations, and how the diffusion of knowledge occurs. QFD can also be one those main tools of CE as this identifies the customer’s main requirements translating into the features required for products. The field survey of exploratory and descriptive type, using the questionnaire as data collection technique, was carried out in the manufacturing companies in the fast growing sectors of automobile industries in the State of Parana located in the Southern of Brazil. The selection of sample companies was made intentionally to guarantee of return of answer through the accessibility criteria. The reasons for this fact that can be pointed out are: the use of “home made” methodology to fulfill customer’s requirements, unknowing of the methodology, and the lack of adequate training to use QFD. It is expected that the results of findings, if disseminated adequately among local companies, will help to enhance the competitiveness performance beyond the local market scenario.

The purpose of this paper is to present a method to quantify the costs of potential losses from production processes for new products to prioritize improvement projects based on the target cost and provide data and information for feasibility studies of continuous improvement projects. The specificity of the manufacturing cost policy deployment for new products is to identify the percentage of cost of future production phases which does not add value from a customer perspective, dynamically throughout the product life cycle. The percentage of non-value added cost is based on loss of each manufacturing process and is determined scientifically based on data and facts. Using the proposed method helps manufacturing companies in the acceptance of certain orders which at first glance are unprofitable. Moreover, the proposed method will help develop scenarios for continuous cost reduction after starting production through continuous improvement of productivity and quality required. The empirical results are based on the study during a year and a half in the automotive company, using action research methodology.

Purpose: The research objectives were to analyze the role of continuous improvement (CI) techniques in manufacturing in Oman in the CI process and to investigate the crucial factors of CI and the application techniques of CI that have been implemented by the manufacturing companies during the CI process. Design/methodology/approach: A survey questionnaire was developed with the baseline of CI practices used by manufacturing companies in Oman and a convenient sampling method was used to collect the data. 146 completely filled-in questionnaires were collected from 75 manufacturing units out of the entire Public Establishment database. The data was tabulated, compiled. The robustness was tested along with the ranking tests and the factor analysis using SPSS and AMOS. Findings: The results reveal that the Omani manufacturing companies using structured CI programs had lesser product recalls, leading to increased overall sales, decrease in processing time. Further, it is also revealed that the CI culture and Employee Performance Measurement and Review are instrumental in translating into company savings. Research limitations/implications: This research was limited to Sohar Industrial estate only. As there are nine industrial estates in Oman, the research can be undertaken to study the CI practices adoption in all the other industrial estates as well. Social implications: Countries from all over the world are facing numerous challenges due to COVID-19. The paper will help the manufacturing companies in decision making towards the process improvement. Originality/Value: There are not many studies on continuous improvement practices within the Omani manufacturing industry and this paper examines the status of CI implementation in manufacturing companies in Oman.

PurposeDelivering premium services and quality products are critical strategies for success in manufacturing. Continuous improvement (CI), as an underlying foundation for quality management, is an ongoing effort allowing manufacturing companies to see beyond the present to create a bright future. We propose a novel integrated fuzzy framework for analyzing the barriers to the implementation of CI in manufacturing companies.Design/methodology/approachWe use the fuzzy failure mode and effect analysis (FMEA) and a fuzzy Shannon's entropy to identify and weigh the most significant barriers. We then use fuzzy multi-objective optimization based on ratio analysis (MOORA), the fuzzy technique for order of preference by similarity to ideal solution (TOPSIS) and fuzzy simple additive weighting (SAW) methods for prioritizing and ranking the barriers with each method. Finally, we aggregate these results with Copeland's method and extract the main CI implementation barriers in manufacturing.FindingsWe show “low cooperation and integration of the team in CI activities” is the most important barrier in CI implementation. Other important barriers are “limited management support in CI activities,” “low employee involvement in CI activities,” “weak communication system in the organization,” and “lack of knowledge in the organization to implement CI projects.”Originality/valueWe initially identify the barriers to the implementation of CI through rigorous literature review and then apply a unique integrated fuzzy approach to identify the most important barriers based on the opinions of industry experts and academics.

Purpose The purpose of this paper is to explore the effects of innovation orientation (IO) on both the implementation levels of soft and hard lean management (LM), as well as innovation performance. It also aims at exploring the effects of soft and hard LM on innovation performance. Design/methodology/approach The study analyzes survey data collected as a part of a high-performance manufacturing (HPM) project from 238 international manufacturing companies in eight countries and three industries. Exploratory factor analysis and confirmatory factor analysis were applied to assess construct validity. The study hypotheses were tested using structural equation modeling. Findings The results demonstrated that innovation-oriented companies tend to adopt aspects of both soft and hard LM. However, the results revealed an insignificant effect of soft and hard LM on innovation performance. The study also showed that innovation performance is positively influenced by an IO. These results indicate that having an IO is vital for enhancing both LM as well as innovation performance. They also evidently suggest that LM is more related to continuous improvement (incremental innovation) rather than (radical) innovation and, as such, is not important for firm’s intent on enhancing their innovation performance. Practical implications The current study demonstrates that IO and LM are complementary and not contradicting strategies. The two strategies share many cultural aspects, similarities and commonalities. However, LM is not sufficient to predict innovation performance. Managers of the surveyed manufacturing firms are advised to focus on IO, as it has beneficial impacts on both LM (continuous improvement initiatives) as well as innovation performance. This clearly indicates that placing the emphasis upon radical (innovative) improvement rather than incremental improvement (LM practices) is believed to support continuous and innovative improvement alike. Originality/value The relationship between LM and innovation is debated in the existing literature, but the debate is characterized by a lack of empirical evidence. This is one of the first studies that empirically investigates the relationships between IO, LM and innovation performance. It identifies some new insights to direct future research, particularly regarding different innovation types as well as in service organizations.
