Flexible circuit materials

Abstract Purpose – To provide an overview of a process for making proper selection of base materials for use in the manufacture of flexible circuits. Design/methodology/approach – The paper provides an introductory review of the desirable attributes for flexible circuit substrates and includes a description of the attribute and its specific role and impact on the finished product. Findings – The paper highlights the importance of making informed materials choices in flexible circuit manufacture. Flexible circuits are an increasingly important member of the family of electronic interconnection technologies and are also the fastest growing. A variety of materials can be used for flexible circuit construction, however, the choice must be tempered by the manufacturing and assembly processes and the application of the finished product. Research limitations/implications – The paper provides a limited overview of the desirable properties of flexible circuit materials and is designed to provide initial background and guidance for making more informed decisions about material choices. Originality/value – This paper provides an overview of the various factors that should be considered in advance of committing to a flex circuit design.
