Electronic Materials and Components

High-tech ...in your palm

Waves of Microelectronics are sweeping the every accessible device and electronic equipment. Amid rapid technological innovation, the lead time from development to commercialization is becoming drastically shortened and high technology is put to use one after another as palm-sized products. Fujikura has a long history of developing a wide variety of wiring materials from their development and prototype production to mass-production. We intend to supply high-tech electronic components as system products that satisfy user needs.
This is our policy for electronic component development at Fujikura as a comprehensive wiring system creator.

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.
