Hinge FPC-2


As cell phones nowadays has come to be equipped with a wide variety of functions such as high-pixel cameras and IC cards, FPCs as internal wiring materials also need to increase the number of signal lines and the speed of response. As the hinge area, however, has only limited wiring space, more than one-sided FPCs have to be piled up to save space. For this reason, Fujikura has commercialized multilayer boards with a hollow structure by not bonding layers in the bending area each other so as to maintain both of multilayer and flexibility of the FPC at one time. These products have an extremely long life-time to endure 100,000 bendings or higher although they are a multilayer board consisted of two to four single-sided FPCs. In addition, we are ready to provide optimal proposals for actual product design based on the accumulated data on FPCs made of different materials and pattern designs through durability tests that simulate the operations of actual cell phones.
