Flexible circuit board is a highly reliable and excellent flexible printed circuit board based on polyimide or polyester film. It has the characteristics of high density, light weight, thin thickness and good bending. By embedding circuit design on flexible thin plastic sheet, a large number of precision components are stacked in narrow and limited space to form a flexible circuit. This kind of circuit can bend at will, fold the weight light, the volume is small, the heat dissipation is good, the installation is convenient, broke through the traditional interconnection technology.
Flexible PCBs offer a host of innovative end uses due to use of a flexible substrate that allows the loaded PCB to conform to contours inside an electronic device. The device can be lightweight and gives product designer greater options.

Single-sided flexible circuits are the simplest and there for cheapest, consisting of a single conductor layer on a flexible dielectric film with the option of a coverlay or semi flexible liquid photo-imageable solder resist (for some flex & stay applications). Parts of the flexible can be made more rigid by the use of additional stiffeners.
2. Double-sided flexible PCB
Double sided flexible PCB consist of two copper layers with a dielectric layer in between ，Normally connected with plated through holes, with the option of coverlay or semi flexible liquid photo-imageable solder resist (for some flex & stay applications). Parts of the flexible can be made more rigid by the use of additional stiffeners.
3. Multilayer flex PCB
Multilayer flex PCB consist of three or more copper layers with a dielectric layer in between, normally connected with plated through holes, with the option of coverlay or semi flexible liquid photo-imageable solder resist (for some flex & stay applications). Parts of the flexible can be made more rigid by the use of additional stiffeners.
4. Rigid-flex PCB
Rigid-flex PCB consist of a mixture of flexible copper conductor layers on dielectric film & rigid copper material, normally connected with plated through holes. Coverlay are applied to the flexible copper conductor layer & liquid photo-imageable solder resist applied to the rigid areas.
Introduction to the composition of the flexible board
1. Dielectric layer
It is used to maintain the insulation between the circuit and each layer, commonly known as the FCCL substrate.
2. Silkscreen
This is a non-essential structure. The main function is to mark the name and position frame of each part on the circuit board, which is convenient for maintenance and identification after assembly.
3. Lines and drawings
The circuit is used as a tool for conduction between the components. In the design, a large copper surface will be designed as a grounding and power supply layer. Lines and drawings are made at the same time.
4. Surface treatment
The main factor that directly determines the quality of an FPC flexible circuit board is the surface treatment process. At present, the more common surface treatment processes are immersion gold, immersion silver, gold plating, tin plating, OSP, etc.
5. Coverlay
The FPC coverlay can also be called a protective film. The main function is to protect the copper foil from being exposed to the air, to avoid oxidation of the copper foil, to cover lines in the subsequent process such as surface treatment, and to act as a solder mask in SMT process.
6. Holes
The via hole can make the lines of more than two layers conduct each other.
