Flexible circuit : ウィキペディア英語版 | Flexible circuit Flexible circuits (also variously referred to around the globe as flex circuits, flexible printed circuit boards, flex print, flexi-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 (normally of copper) 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. ==Rigid Flexible Circuits==
Rigid Flexible Circuits can have circuit boards both externally or internally. They consist of multiple inner layers of flexible circuits. Advantages in rigid flexible circuits include high reliability and flexibility in design options.〔(【引用サイトリンク】url=http://www.flexiblecircuit.com/products/rigid-flex/ )〕 Rigid flexible circuits contain more materials than flat flexible circuits. The materials include rolled annealed copper, electro deposited copper, epoxy, acrylic, pre-preg, pressure sensitive, adhesiveless base material, FR-4, polyimide, polyester, solder mask, flexible solder mask, and photo image-able cover lay.〔(【引用サイトリンク】url=http://www.flexiblecircuit.com/products/rigid-flex/materials.php )〕 Rigid flexible circuits are found in electronic products in many areas, such as, in the military and the medical field.〔(【引用サイトリンク】url=http://www.flexiblecircuit.com/products/rigid-flex/applications.php )〕
