Description
Technical field
The utility model belongs to flexible circuit board technical field, particularly a kind of flexible circuit board of new Joining Structure.
Background technology
Simultaneously, flexible PCB is as printed circuit board (PCB) that can integrally bending, have that distribution density is high, lightweight, the feature of thin thickness, be widely used in the electronic products such as mobile phone, digital camera, notebook computer and PDA, current existing single-sided flexible circuit board has the shortcoming that volume ratio is larger, in the time of some component movement of above-mentioned electronic product, be overlapped on the also corresponding and then movement along with the motion of these parts of flexible PCB between these parts, therefore the phenomenon that occurs sometimes in actual use friction sound, has affected result of use.
Simultaneously, along with electronic product is all the more to light, thin, short, little trend development, the closeness of circuit board component improves, and the installation control of circuit board diminishes, bending radius when flexible PCB is installed also diminishes thereupon, and this just requires flexible PCB to have better controlled deflection performance.
Utility model content
The purpose of this utility model is to overcome the shortcoming existing in prior art with not enough, and a kind of flexible circuit board of new Joining Structure is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of flexible circuit board of new Joining Structure, comprises matrix, flexible glue and plain conductor; Described matrix has two; Described matrix is connected with plain conductor by flexible glue, and described plain conductor is arranged in flexible glue;
Described matrix comprises metallic conductor, insulator and dielectric film, described metallic conductor is arranged in insulator, described dielectric film wraps metallic conductor and insulator, on described insulator and dielectric film, be distributed with raised strip, the width of raised strip and interval need to arrange depending on flexible PCB practicality; Connection between two matrixes, connects by flexible glue between described insulator, between described dielectric film, connects by flexible glue, between described metallic conductor, connects by plain conductor.
Described insulator and the thickness of dielectric film are preferably 0.08-0.12mm, and described raised strip height is preferably 0.09-0.10mm.
The utility model has following advantage and effect with respect to prior art:
The utility model adopts combination conjoined structure, guaranteed whole structure in dwindling unit volume, and two matrixes connect by two-part, do not affect bending fold, have effectively eliminated friction sound; Simultaneously, on insulator and dielectric film, be provided with raised strip, make the attenuation of flexible circuit board local thickness, be more conducive to the bending (degree of crook is than having improved more than 15% without the flexible circuit board of raised strip structure) of circuit board, and bulge-structure also contributes to improve the radiating effect (radiating efficiency is than having improved more than 25% without the flexible circuit board of raised strip structure) of flexible PCB.
