context_page_description: Flexible circuits are members of electronic and interconnection family. They consist of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits. The technology has been used for interconnecting electronic devices since the 1950s in one form or another. It is now one of the most important interconnection technologies in use for the manufacture of many of today's most advanced electronic products.
  In practice there are many different kinds of flexible circuits, including one metal layer, double sided, multilayer and rigid flex circuits. The circuits can be formed by etching metal foil cladding from polymer bases, plating metal or printing of conductive inks among other processes. Flexible circuits may or may not have components attached. When components are attached, they are considered by some in the industry to be flexible electronic assemblies.
context_section_description: Flat flexible circuits are able to fold into nearly any shape due to their flexibility and smaller size. Although they are small and light-weight, they are durable and capable of handling high density. Materials in flat flexible circuits include bare copper, tin-plated copper, acrylic, pressure sensitive adhesives, polyester, photoinduced electron transfer, polyethylene naphthalate, tin, conductive silver ink, and aluminum or copper tape. Typical applications of flat flexible circuits include plotters, copiers, and printers.
