FFC flexible flat cable is most suitable for data transmission cables between moving parts and motherboards, between PCB boards and PCB boards, and in miniaturized electrical equipment. In the process of data transmission, electromagnetic interference will also easily occur. When some EMI problems cannot be solved by shielding means (such as copper foil, aluminum foil, conductive cloth), absorbing materials can come in handy. The main uses of absorbing materials on FFC cables are as follows:
1. Absorb electromagnetic radiation and interference
2. Isolate the coupling interference caused by the segment between two adjacent components.
3. Reduce instability caused by radiation interference.
4. Prevent electromagnetic wave leakage.
5. Reduce the surface current induced by the shield.
The use of absorbing materials does not need to make any changes to the design and process, just find the interference source and then paste it with the absorbing material, without grounding, it is an advanced means of absorbing and eliminating electromagnetic waves. Can be widely used in flat cables and FPC flexible circuit boards, smart phones, integrated circuits and PCBs, IC cards, PC computer peripherals, PDA handheld computers, Bluetooth, wireless antennas, scanners, micro motors, Wi-Fi wireless networks, notebooks Computer CPU or NFC mobile phone, wireless LAN, digital camera and other microwave communication equipment, optical fiber communication technology, LNB tuner, BOX shielding box, ITS intelligent transportation system, satellite system tuner, optical transmission, etc.
