FFC flat cable is a new type of data cable, which is made of PET insulation material and extremely thin tinned flat copper wire, so it is also called flexible flat cable connector. TXGA, a ffc flat cable manufacturer, is a professional connector manufacturer with a strong production capacity, with a daily output of one million, sufficient inventory, and complete models. Welcome to the [product center] online purchase.
When the FFC flat cable is used in the environment, the signal electromagnetic wave on the cable will interact with other electronic components in the motherboard, causing interference, which is called EMI. For example, if the lvds FFC cable of the LCD TV is interfered, it will cause the LCD TV's display to be interfered, and the common "snowflakes" will appear. This is because there are discontinuous conductive points on the FFC flexible cable. These non-conductive gaps form electromagnetic leakage on the surface of the FFC cable, causing electromagnetic waves to interfere with electronic components.
To truly solve the electromagnetic interference of FFC, two conditions need to be met: the entire surface of the shield must be conductive and continuous, and the electromagnetic cannot directly penetrate the conductor of the shield.
Therefore, it is necessary to connect the discontinuous conductive points on the surface of the FFC flat cable to form a monolithic conductive body. Therefore, the FFC flexible flat cable surface is covered with conductive cloth, aluminum foil, copper foil, silver paste mesh, black electromagnetic film, single-sided or double-sided black absorbing material. This can form a continuous seamless conductor layer on the surface of the ffc flexible cable. The outer layer of the FFC flat cable is a non-conductive hot melt adhesive film. The base material of this film is an insulator, so it also meets the second condition for solving electromagnetic interference: electromagnetic does not penetrate the shield (FFC row Wire) conductor.
When both conditions are met, it is our common FFC flat cable with a certain anti-interference function. If the application environment is more complex and the device faces severe transmission interference, the interference function of the connector can be enhanced through customization. TXGA's 16-year high-quality brand serves our customers with excellent product quality. The professional technical team responds to the after-sales service and provides technical support.
