Description

A kind of flexible PCB
Technical field
This utility model is related in printed-board technology field, especially a kind of flexible PCB.
Background technology
LED, with respect to conventional incandescent lights, is a kind of resource-conserving, environmentally friendly green light source, with complete The impact of ball energy crisis, the indoor and outdoors Lighting Design product being done by LED light source is real-life using increasingly Extensively, particularly LED lamp bar has been widely used for illumination and decoration occasion, and the kerve in existing LED lamp bar and substrate are harder, curved Limited by bent amplitude, during installation and use, it is possible that lamp body cracking phenomena, reduce the water resistance of LED lamp bar, If moisture enters the conductive body component in LED lamp bar, LED lamp bar can be damaged, so can increase illumination cost, cause to waste.
Therefore, in order to various electronic devices and components are more easily installed in scene, flexible PCB is as a kind of Novel electric Road plate, is widely applied to every field.Flexible PCB is the printed circuit board (PCB) made with flexible insulating substrate, can be certainly By bending, winding, fold, can require arbitrarily to arrange, and arbitrarily move and flexible in three dimensions according to space layout, thus Reach the integration that components and parts assembling and wire connect.But, flexible PCB of the prior art is to set for special applications Meter, manufacture, have the disadvantage that during use:
1st, contour structures are usually relatively complex and irregularly, in the fabrication process, processing technique is complicated, produces qualification rate Low.
Once the 2, more than 90 degree, circuit board and circuit are very easily by the broken even fracture of folding for the angle of circuit board bending.
3rd, in the application scenario that some deformation intensity are larger, such as:Wearable device, using flexible PCB, service life is simultaneously Not long.
Utility model content
The technical problems to be solved in the utility model is:Overcome the deficiencies in the prior art, a kind of flexible PCB is provided, its The processing technique that structure is simple, simplify flexible PCB, production qualification rate are high, the bending of the circuit board made, winding, folding Intensity is big, long service life.
This utility model solves its technical problem and be employed technical scheme comprise that:A kind of flexible PCB it is characterised in that: Including flexible circuit board substrate, copper conductor and dielectric film, described copper conductor is pressed together on the upper of flexible circuit board substrate, described insulation Mould on flexible circuit board substrate, described dielectric film offers corresponding copper conductor shape window make copper conductor exposed Dielectric film top.
Further improved it is:Described copper conductor is circular or square or sheet-shaped.
The beneficial effects of the utility model are:Flexible PCB contour structures after molding are simple, and processing technique is simple, Set on flexible PCB above placement copper conductor, then the locating slot corresponding with copper conductor shape is opened up on dielectric film, convenient Various electronic devices and components and copper conductor are fitted and connected, and simplify the combined process of components and parts and flexible circuit board substrate, and product Qualification rate is high.Using the pliability of the flexible PCB of this kind of technological forming is good, bending and deformation intensity are larger, it is applicable to one A little larger application scenarios of deformation intensity, such as:The use of wearable device, during being less prone to flexible PCB and circuit use Phenomenon by the broken even fracture of folding.
Brief description:
Fig. 1 is the structural representation of this utility model flexible PCB.
Specific embodiment
Presently in connection with embodiment, this utility model is further described.As Fig. 1, this utility model embodiment discloses one Plant flexible PCB, including flexible circuit board substrate 1, rounded copper wire 2 and dielectric film 3, described copper conductor 2 is pressed together on flexible electrical On road plate substrate 1, described dielectric film 3 is pressed on flexible circuit board substrate 1, and described dielectric film 3 offers corresponding copper conductor The window 31 of shape makes the exposed portion on the insulating film 3 of copper conductor.
A kind of manufacture method of flexible PCB, including following making step:
1), by copper conductor strong for pliability, flexible circuit board substrate is placed into certain elasticity and processing technique Top;
2), the locating slot corresponding with copper conductor shape is opened up on dielectric film, allow respective regions copper conductor exposed Outward, convenient device is sticked or is fabricated to board pads;
3), by circuit board substrate, wire and dielectric film pressing and forming be circuit board.
Flexible PCB contour structures after molding are simple, and processing technique is simple, opens up and copper conductor shape on dielectric film The corresponding locating slot of shape, facilitates various electronic devices and components and copper conductor to be fitted and connected, and simplifies components and parts and flexible PCB base The combined process of plate, and conforming product rate is high.Using the pliability of the flexible PCB of this kind of technological forming is good, bending and shape Intensity adjustable is larger, is applicable to the larger application scenario of some deformation intensity, such as:The use of wearable device, is less prone to flexibility By the phenomenon of the broken even fracture of folding during circuit board and circuit use.
Based on preceding solution, described copper conductor 2 can also be shape or the flake shape such as oval or square, only It to achieve that the purpose of this utility model with being connected of flexible circuit board substrate 1 surface.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people Member can carry out various change and modification completely in the range of without departing from this utility model technological thought.This reality The content being not limited in description with new technical scope it is necessary to determine its technology according to right Property scope.
