What flexible circuit boards used in flexible LED light belt, and what are the advantages and disadvantages?

 

 LED light belt, which is often called flexible LED lamp belt, uses flexible circuit board, which is soft and dexterous, folding and bending resistant, and has high flexibility. It is widely used to make linear lighting products such as lamp belt.
The unique characteristics of flexible circuit board make it a rigid circuit board in many occasions, and also promote the development of many fields.
Common types of flexible circuit board:
1. Single panel
A single-sided PI copper clad plate is used to cover a layer of protective film after the circuit is completed to form a flexible circuit board with only a single-layer conductor
2. Ordinary double-sided board
After the double-sided circuit is completed, a protective film is added on both sides to form a circuit board with double-layer conductors
3. Single panel generated from substrate
Using pure copper foil material, a protective film is added on both sides of the circuit to form a circuit board with only a single-layer conductor, but conductors are exposed on both sides of the circuit board
4. The base plate generates a double-sided board
Two layers of single-sided PI copper clad plate materials are used for pressing, supplemented by adhesive with windows at specific positions, to form a double-sided conductor circuit board with two-layer separation structure in local areas, so as to achieve a circuit board with high flexural performance in layered areas.
There are four types of flexible circuit boards.
Advantages of flexible circuit board:
1. It can be bent, wound and folded freely, and can be arranged arbitrarily according to the spatial layout requirements
2. Using FPC can greatly reduce the volume and weight of electronic products
3. FPC also has good heat dissipation and weldability, easy assembly and connection, and low comprehensive cost
Disadvantages of flexible circuit board:
1. High one-time initial cost
Since the flexible PCB circuit board is designed for special applications, the cost of circuit design, wiring and photographic base plate is high, unless there is a special need to apply the flexible PCB
2. It is difficult to change and repair the flexible PCB
Once the flexible PCB circuit board is made, it must be changed from the base map or the prepared photo drawing program, so it is not easy to change. Its surface is covered with a protective film, which should be removed before repair and restored after repair, which is a difficult work.
3. Limited size
When the flexible PCB circuit board is not popular, it is usually manufactured by batch process. Therefore, it can not be made very long and wide due to the limitation of the size of production equipment.
4. Improper operation is easy to damage
