PCB is an electrically conductive circuit for a desired electric function. The semi-conductor industry is constantly trying to increase circuit density, reliability and miniaturisation and meet stringent economic demands. Unlike the rigid PCB , Flexible PCB or Flex Circuit is designed to specific dimensions, current carrying capacity and geometric shape of the package and is being increasingly used in computers and electronic equipment, telecommunications, military and aerospace applications. Flex Circuits are the most sophisticated and versatile interconnection method ever designed and has the following distinctive features.
