Module Overview

Manufacturing and Maintenance

The aim of the module is to provide the student with an overview of design and reliability methodologies used in electronic manufacturing. The introduction to the module deals with different aspects of circuit board design and development and technologies involved in this area. This leads on to how components are packaged, assembled, the chronological development of printed circuits board technologies and the use of automation in the electronic manufacturing and testing process. The second part of the module is dedicated to analytical aspects of reliability engineering providing a comprehensive description of important analytical methods that influence design, development, manufacture of engineering products and systems. A pragmatic approach is taken where possible covering maintenance strategies applicable in the electronic manufacturing process and process simulation from a reliability perspective.
