Chapter 5 – Flexible Circuit Material Flexible base materials are the foundation of every flexible circuit in use today. A wide variety of dielectric materials, adhesives and conductors are used in their fabrication. The substantive examination of materials in Chapter 5 brings into focus the desirable characteristics for flexible circuit laminates, basic construction elements for manufacture, flexible circuit material formats and properties, adhesives, metal foil, metallic coatings and other conductor material. Helpful tables are included that compare material cost, characteristics and properties. |
