A type of flexible printed circuits, short for FPC, are quite frequently used as connectors in a great variety of applications where flexibility, space savings, or production constraints limit the service ability of rigid circuit boards or hand wiring.
The surface of FPC is generally processed as gold immersion, anti-oxidation, gold or tin plating. FPC largely saves time for assembly by configuring all necessary cables well. Being waterproof, quakeproof, greaseproof，high temperature resisting and easy soldering makes FPC more suitable for electronics. Besides，the FPC is also characteristic for its free bending, winding and folding.
A common application of flexible printed circuits is in computer keyboards; most keyboards use flexible circuits for the switch matrix.
Moreover, organic light-emitting diodes are usually adopted instead of a back-light for flexible displays, making a flexible organic light-emitting diode display.
Most flexible circuits are passive wiring structures which are used to interconnect electronic components such as integrated circuits, resistor, capacitors etc, but some are used only for making interconnections between other electronic assemblies either directly or by means of connectors.
Hereby below comes an example:
After Amazon successfully brought Kindle ebook reader to Chinese Mainland market, Amazon hardware product localization moves another step forward this week. It's announced that Kindle Fire HD series tablets that have taken a big hit on market abroad will officially land on Chinese Mainland market.Amazon will launch Kindle Fire HD series tablets in online platform shopping mall.
The 8.9 inch wide Kindle Fire HD tablet is only 8.8mm thick, even thinner than new iPad, and weighs 567 grammes. It is very convenient to carry. Thanks to flexible printed circuit Kindle Fire HD tablet uses, compared with traditional FPC, new FPC was designed to be lighter, thinner and its performance turns greater, so does its stability and durability.
On the other hand, Kindle Fire HD tablet uses 5GHz instead of 2.4GHz for its wireless network. At the meantime, double antenna design solves frequency range jam effectively.
Kindle Fire HD adds 100,000 audio books. The words and audio book can be synchronized, and so is synchronized for vedio games. Kindle Fire HD's new freetime is also attractive,
which is set for children users. Freetime can be adjusted under different circumstances. For example, Freetime sets time for reading, vedio watching and other application programmes like vedio games.
