When it comes to FPC cables, everyone must know or be familiar with what FPC cables are? According to the function, the flexible circuit board can be divided into many kinds, such as FPC antenna, FPC touch screen, FPC capacitive screen, etc. FPC cable is one of them. In layman's terms, FPC cable is a connection that can be bent to a certain extent. line group. The function of the FPC cable is to connect two related electronic components. The application field of FPC cable is widely used to connect electronic parts and ultra-thin products with low resistance and need to slide. Such as various electronic read-write heads, scanners, printers, DVD players, PDAs, automotive and aerospace instruments, accessories, walkie-talkies, micro-motors, etc. Mobile, visual, laptop, aerospace,medical equipment, digital cameras, high-end automotive instruments and other pressing modules or connecting parts of liquid crystal chips FPC flexible circuit is small in size and light in weight.

The original design of flexible circuit board is to use It is used to replace the bulky harness wires.

Because FPC cable is a kind of FPC, its composition is the same as that of FPC. FPC is generally strip-shaped, and the two ends are designed as pluggable needles, which can be directly connected to the connector or welded on the product. The middle is generally a circuit, because FPC cables require a certain degree of flexibility, therefore, the base material is generally made of rolled copper, which is resistant to twists and turns and is flexible. Cable parameters: the minimum line width and line spacing are 3mil/3mil, and the minimum line hole finished product reaches 0.15mm. The surface treatment process used for FPC flexible board wiring is generally immersion gold, and occasionally has anti-oxidation. However, the anti-oxidation process cannot withstand high temperatures, and its environmental tolerance is worse than that of immersion gold, and the price of the t wo is similar. Therefore, most of them use the immersion gold process. In addition, there are processes such as tin plating and tin spraying, but the temperature resistance of FPC is generally below 280 degrees Celsius, while the temperature of spraying tin will be above 300 degrees Celsius, and the hardness of the solder paste is relatively small, so it is rarely used.

Unlike other products, FPC cables are actually not in contact with air and water. So how should we store this product properly? I believe that after reading the following content, everyone will find the answer. First of all, the vacuum of the FPc flexible circuit board cannot be damaged. When packing the box, a layer of bubble film needs to be surrounded on the side of the box. The water absorption of the bubble film is better, which plays a very good role in preventing moisture. Of course, moisture-proof beads are also indispensable. of. Secondly, after the box is sealed, the box must be stored in a dry and ventilated place with a partition wall and off the ground, and avoid sunlight. The temperature of the warehouse is best controlled at 23±3°C, 55±10%RH. Under such conditions, PCB boards with surface treatments such as immersion gold, electro-gold, HASL, and silver plating can generally be stored for 6 months. Surface-treated PcB boards such as immersion tin and OSP can generally be stored for 3 months.
