It is well known that with the continuous popularization and development of high-end miniaturized electronic products such as mobile phones, PDAs, and notebook computers, the demand for reliable FPCs is increasing, and the market trend of FPC has become the vane of the entire electronics industry. Accelerate the development of FPCs with lighter weight, thinner thickness and higher density, in order to let everyone better understand the specific types of FPC.

First, there is a single layer of FPC

A single-layer FPC is a layer of chemically etched conductive pattern. It should be noted here that the conductive pattern on the surface of a flexible insulating substrate such as polyimide or ethylene glycol ester is a rolled copper foil. In addition, single-layer FPC can also be classified according to single or double-sided connection, with or without cover layer. Among them, FPC with one-sided connection of cover layer is a kind of application and wide, especially in electronic instruments and automotive instruments. .

Second, there are two-sided FPC

The double-sided FPC has a layer of chemically etched conductive pattern on both sides of the insulating base film. Compared with the single-sided FPC, not only a layer of conductive pattern but also a wiring density per unit area is added. It is said that the double-sided FPC is connected by a metallized hole to form a pattern on both sides thereof to satisfy the design of the flexibility and various functions of use, and the safe placement of the wires is protected by the cover film.

Third, there are multiple layers of FPC

It is undoubted that the multi-layer FPC laminates three or more layers of single-sided, double-sided flexible circuits together, and forms metallized holes by electroplating to realize conductive paths between different layers. According to the manufacturer, the multi-layer FPC not only has more High reliability, better thermal conductivity and more convenient assembly, the great difference in function is also obvious.

Throughout the above introduction to the specific types of FPC, we can know that FPC products not only have single and double layers, but also more layers. It is undeniable that each FPC has its own different features, advantages and uses. The scope of the field, so users need to choose the reputable FPC manufacturers to purchase according to their specific needs.
