flexible LED strips, the use of flexible circuit boards, soft and dexterous, folding and bending resistance, flexibility is very high, widely used in the production of linear lighting products such as light strips.
The unique characteristics of flexible circuit board make it a rigid circuit board in many occasions, while also promoting the development of many fields.
Common types of flexible circuit boards.
The use of single-sided PI copper sheet in the line is completed, and then covered with a layer of protective film, forming a flexible circuit board with only a single layer of conductors
2.Ordinary double-sided board
Using double-sided PI laminate material on both sides of the circuit is completed, both sides are covered with a layer of protective film to form a double-layer conductor circuit board
3.Substrate generation single board
Using pure copper foil material in the circuit production, respectively, in the successive two sides of each layer of protective film, to become a single layer of conductors but in both sides of the circuit board have conductors exposed circuit board
4. Substrate generation of double-sided
The use of two single-sided PI copper-laminate material is supplemented by a bonding adhesive in the middle of the window at a specific location for lamination, becoming a double-sided conductor circuit board with a lamination in the local area and a separation structure of the two layers in the local area to achieve a circuit board with high flexural properties in the layered area.
Flexible circuit boards are mainly of the above four types.
The advantages of flexible circuit boards.
1. Free bending, winding, folding, can be arranged according to the space layout requirements at will
2. The use of FPC can greatly reduce the size and weight of electronic products
3. FPC also has good heat dissipation and solderability and easy to install even, the comprehensive cost is low
Disadvantages of flexible circuit boards.
1. High one-time initial cost
As the flexible PCB circuit board is designed for special applications, circuit design, wiring and photographic backplane required higher costs, unless there is a special need to apply flexible PCB
2. Flexible PCB changes and repair is more difficult
Flexible PCB circuit board once made, to change the bottom of the map or the preparation of the light drawing program to start, so it is not easy to change. Its surface is covered with a protective film, to remove before repair, repair and recovery, which is more difficult to work.
3. Size is limited
Flexible PCB circuit boards in the case of not yet widespread, usually with intermittent process manufacturing, and therefore subject to the size of the production equipment limitations, can not be made very long, very wide.
4. Improper operation is easy to damage
