Flexible pcbs are manufactured on a substrate of polyimide, and are free to bend, which
Allows the installation of such boards in places, as well as use them as a flexible
Connector. Flexible boards allow increased density mounting of electronic devices,
Effectively using 3-d space.
Basic materials: polyimide
Thickness: 12.5 - 200 microns
Surface finish: tin immersion and gold flash
