FPC flexible board is mainly used in the connection parts of electronic products, such as mobile phone cable, LCD module, etc. Compared with the hard board, it is smaller in size and lighter in weight, and can realize the advantages of bending, flexing, three-dimensional assembly, etc. Generally, most soft boards need to be attached with components.
According to the layers of conductive copper foil, it can be divided into single-layer board, double-layer board, multi-layer board, double-sided board, etc.
Single layer plate structure: the flexible plate of this structure is the flexible plate of the simplest structure. Generally, the base material transparent adhesive copper foil is a set of purchased raw materials, while the protective film transparent adhesive is another kind of purchased raw materials.
Double sided board structure: both sides of the double sided board have pads, which are mainly used for connection with other circuit boards. Although its structure is similar to that of single layer board, its manufacturing process is very different.
1. It can bend, wind and fold freely, can be arranged arbitrarily according to the space layout requirements, and can move and expand freely in three-dimensional space, so as to achieve the integration of component assembly and wire connection.
2. The volume and weight of electronic products can be greatly reduced by using FPC, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, FPC flexible plate has been widely used in aerospace, military, mobile communication, laptop, computer peripherals, PDA, digital cameras and other fields or products.
3. FPC flexible plate also has the advantages of good heat dissipation and weldability, easy assembly and connection, low comprehensive cost, etc. The design of soft hard combination also makes up for the slight shortage of the flexible substrate in the component bearing capacity to a certain extent.
