Introduction of a New Baffle-Plate Concept to Control the Gas Flow Behavior in a Large Volume PECVD Chamber

引用

Open Journal of Fluid Dynamics 2018年第2期8卷 141-160页

作者： Gustavo Simiema de Freitas Barbosa Klaus Vissing Bernd Mayer Fraunhofer Institute for manufacturing Technology and Advanced Materials (IFAM) Wiener Stra&szlig e 12 Bremen Germany University of Bremen Faculty of Production Engineering Badgasteiner Stra&szlig e 1 Bremen Germany

Achieving a reasonable homogeneity of the coating deposition rate within a low-pressure plasma process is a challenge, especially in large volume chambers. The local gas flow behavior is one key parameter in the coating deposition. Basically, with the exception of the product geometry and the electrode design, there are two main influences on the gas flow distribution inside a large volume chamber: 1) gas feed-in system and 2) gas exhaustion system. This work focuses on the gas exhaustion system with the aim to reduce its influence on the gas flow behavior inside a large plasma coater. In this sense, a solution with a perforated plate, named “Baffle-Plate”, is created. Thereby relevant construction parameters are identified and investigated to understand their influence in respect to the homogeneity of the gas exhaustion. Number of holes, hole diameter, distance of the Baffle-Plate to the top of the chamber, gas flow and chamber volume are evaluated parameters. Computational fluid dynamics (CFD) simulations are used as a tool to determine velocity and pressure distribution inside the PECVD-chamber and, consequently, to evaluate the layout parameters of the Baffle-Plate. Additionally, practical coating experiments with and without the Baffle-Plate installed are performed. The results show a correlation between the gas flow distribution and the homogeneity of the coating deposition rate. With these results construction guidelines have been formulated. Hence in future developments correct technical layouts of the Baffle-Plate can be applied, easily.

作者： Hongbing Wang Chunhua Sun Department of Mechanical & Electrical Engineering Suzhou Vocational University Suzhou China 3C-Product Intelligent manufacturing Engineering Technology Research and Development Center of Jiangsu Province Suzhou China

In recent years, with the rapid development of large-scale distributed wireless sensor systems and micro-power devices, the disadvantages of traditional chemical battery power supply mode are becoming more and more obvious. Piezoelectric energy collector has attracted wide attention because of its simple structure, no heating, no electromagnetic interference, environmental protection and easy miniaturization. Wind energy is a reproducible resource. Wind energy harvester based on piezoelectric intelligent material can be named piezoelectric wind energy harvesting which converts wind energy into electric power and will have great application prospect. To promote the development of piezoelectric wind energy harvesting technology, research statuses on piezoelectric wind energy harvesting technology are reviewed. The existing problem and development direction about piezoelectric wind energy harvester in the future are discussed. The study will be helpful for researchers engaged in piezoelectric wind energy harvesting.

Journal of Mechanics Engineering and Automation 2011年第2期1卷 119-125页

作者： Abioye Taiwo Bello Emmanuel Olabanji Olayinka Department of Mechanical Materials and Manufacturing Engineering University of Nottingham NG7 2RD UK Department of Mechanical Engineering Federal University of Technology PMB 704 Akure Ondo-State Nigeria

The increasing customers’ demands in terms of speed of service and reduced cost at higher quality has generated a new platform on which manufacturing companies compete. This heightened challenge is virtually driving all manufacturing companies to introducing lean manufacturing principles into their production systems. This paper focuses on the analysis of the current state mapping of a case study and then proposes a future state mapping to the company. The extruder 60 production line of Denki wires and cables limited, Akure, Nigeria was carefully evaluated. Data were collected from actual operators on the shop floor and feedbacks from the customers at the Gemba. Denki’s extruder 60 production line production lead time was massively reduced from 38.42 days to 5.16 days with a 12.86% waste reduction. At the end, a practical way of implementing this aspect of lean manufacturing was suggested.
