New development trend of FFC flexible flat cable
FFC flexible cable is widely used, such as intelligent furniture, vehicle electronics, security equipment, medical equipment and so on(1) Smaller and lighter. In order to adapt to the characteristics of thin, light and micro electronic products in the future, FFC will need thinner adhesive film and conductor below 30um to greatly reduce the product quality. Xinmeite Electronic Co., Ltd. launched FFC flat flexible cable series at the electronic components conference, and introduced ultra-thin and ultra flexible 0.12 mm cable, with conductor thickness less than 0.03 mm.
(2) Pin spacing is more dense and the height is smaller. In order to improve the flexibility of the cable and ensure the quality of signal transmission in micro products, some enterprises are studying more high density integrated FFC. Foreign manufacturers have been able to process high-difficulty FFC with conductor spacing less than 0.25 mm. Only a few domestic FFC manufacturers such as xinmeite can do this. However, it also shows that the gap between China and the international in this field is narrowing year by year. In order to reduce the signal reflection and improve the transmission efficiency, it is necessary to control the impedance to achieve impedance matching.
(3) Improvement of FFC material. Generally, the working temperature of FFC is below 80 ¡æ. In the future, the insulation film of FFC may be made of liquid crystal polymer and other materials with high temperature resistance, so that it can be used in worse environment. Special field uses FFC flat wire bare outside of the gold finger gold plating treatment, more antioxidant
(4) Mobile phone market. The mobile phone market is so large, and smart phones have been popularized. Ultra thin fuselage, clear touch screen and high-speed and stable signal connection will further infiltrate FFC flat cable into the mobile phone field. Frequent sliding of sliding cover mobile phone requires bending resistance of 200000-400000 times. FFC will be able to take this responsibility. At present, you are the only one.
