1. What is FPC cable
Speaking of FPC cables, you must know or be familiar with FPC? FPC can be divided into many types according to functions, such as FPC antenna, FPC touch screen, FPC capacitive screen, etc. FPC cable is one of them. Popularly speaking, FPC cable is a group of connecting wires that can be bent to a certain extent.
2. Functional use of FPC cable
The function of the FPC cable is to connect two related parts or products. Now, many products use flat cable, because it has a certain flexibility, FPC cable has been used in many products such as printers, mobile phones, notebooks and so on. The manufacturers of FPC cables are mainly concentrated in the Pearl River Delta region, and Shenzhen is the first of them.
3. FPC cable composition and parameters
Because FPC cable is a kind of FPC, so its composition is the same as that of FPC. The FPC is generally elongated, and the two ends are designed as pluggable pins, which can be directly connected to the connector or welded to the product. The middle is generally a circuit, because FPC cables require a certain degree of flexibility. Therefore, the base material is generally rolled copper, which is resistant to twists and turns and flexible.
4. FPC cable process
The surface treatment process used for FPC cable is generally immersion gold, and occasionally has anti-oxidation. However, the anti-oxidation process cannot withstand high temperatures, and the environmental endurance is worse than that of immersion gold. The prices of the two are 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, and there will be temperatures above 300 degrees Celsius when spraying tin, and the solder paste hardness is small, so it is rarely used.
5. Advantages and disadvantages of FPC cable
Advantages:
The use of FPC can greatly reduce the volume and weight of electronic products, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDAs, digital cameras and other fields or products. In addition, it can also be arranged arbitrarily according to the space layout requirements, and can be arbitrarily moved and stretched in three-dimensional space, so as to achieve the integration of component assembly and wire connection.
Disadvantages:
In the process of producing products, the cost should be the most considered issue. Because the soft FPC is designed and manufactured for special applications, the initial circuit design, wiring, and photographic master plates require higher costs. Unless there is a special need to apply soft FPC, usually when a small amount is used, it is better not to use it. In addition, since a lot of energy has been invested in it, the later maintenance is naturally essential, so soldering and rework require trained personnel to operate.
