What does FPC in a high brightness LCD screen refer to? Speaking of FPC ribbon cables for LCD screens, today I will briefly introduce them to you. FPCs can be divided into many types according to their functions, such as FPC antennas, FPC touch screens, FPC capacitive screens, etc. FPC ribbon cables are one of them. Simply put, FPC ribbon cables are connecting cables. The composition of FPC cable is the same as that of FPC because it is a type of FPC.
FPC is generally a long strip with two ends designed as plug-in needle shaped, which can be directly connected to connectors or welded to products. The middle is usually a circuit, because FPC ribbon cables require a certain degree of flexibility. Therefore, the substrate is generally made of rolled copper, which is resistant to twists and turns and flexible.
The surface treatment process used for FPC ribbon cables is generally gold plating and occasionally anti oxidation. However, the anti oxidation process cannot withstand high temperatures, and its environmental bearing capacity is inferior to that of gold precipitation. The prices of the two are similar, so the vast majority of them use gold precipitation technology. In addition, there are processes such as tin plating and tin spraying, but FPC generally has a temperature resistance below 280 degrees Celsius, while during tin spraying, there will be temperatures above 300 degrees Celsius, and the hardness of the solder paste is relatively small, so it is rarely used.
The function and purpose of FPC lies in connecting two related parts or products. Nowadays, many products use ribbon cables because they have a certain degree of flexibility, and FPC ribbon cables have been used in many products such as printers, phones, and laptops.
