What is FPC in LCD


When it comes to FPC cabling, you must know or be familiar with what FPC is? FPC can be divided into many types according to functions, such as FPC antenna, FPC touch screen, FPC capacitive screen, etc. FPC flat cable is one of them. Generally speaking, FPC flat cable is a connecting cable. FPC flat cable is a kind of FPC, so its composition is the same as that of FPC. FPC is generally long strip, with both ends designed as pluggable needles, which can be directly connected to the connector or welded to the product.


The middle part is generally the line, because FPC flat cable requires a certain degree of flexibility, so the base material is generally calendered copper, which is resistant to twists and turns and flexible. FPC cable laying process The surface treatment process used in FPC cable laying is generally gold deposition, occasionally anti oxidation. However, the anti oxidation process can not withstand high temperatures, and the environmental tolerance is worse than that of gold deposition. The prices of the two are similar. Therefore, most of them adopt gold deposition process.
In addition, there are processes such as tin plating and tin spraying, but the temperature resistance of FPC is generally below 280 ℃, while the temperature of tin spraying is above 300 ℃, and the hardness of solder paste is small, so it is rarely used. The function and usage of FPC The function of FPC flat cable is to connect two related parts or products. Nowadays, many products use FPC cables because of its flexibility. FPC cables have been used in printers, mobile phones, laptops and many other products
