Description
Technical field
This utility model is involved in printed-board technology field, especially a kind of flexible PCB.
Background technology
LED, relative to conventional incandescent lights, is a kind of resource-conserving, environmentally friendly green light source,
Along with the impact of global energy crisis, LED light source the indoor and outdoors Lighting Design product done is in reality
Use in life is increasingly wider, and particularly LED lamp bar has been widely used for illumination and decoration occasion, existing
Kerve and substrate in some LED lamp bar are harder, and bending amplitude is limited, during installing and using,
It is possible that lamp body cracking phenomena, reduce the water resistance of LED lamp bar, if moisture enters LED
Electric conductor parts in bar, can damage LED lamp bar, so can increase illumination cost, cause waste.
Therefore, in order to various electronic devices and components are more easily installed in scene, flexible PCB is as one
Novel circuit board, is widely applied to every field.The insulating substrate of flexible PCB flexibility is made
Printed circuit board (PCB), can with free bend, wind, fold, can require arbitrarily to arrange according to space layout,
And arbitrarily move at three dimensions and stretch, thus reach components and parts assembling and integration that wire connects.
But, flexible PCB of the prior art designs for special applications, manufactures, during use
Have the drawback that
1, contour structures is usually relatively complex and irregularly, in the fabrication process, processing technique is complicated,
Production qualification rate is low.
2, the angle of circuit board once bending is more than 90 degree, and circuit board and circuit are easily the most broken very by folding
To fracture.
3, in the application scenario that some deformation intensity are bigger, such as: wearable device, flexible PCB is used,
Service life is the longest.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that one
Kind of flexible PCB, its simple in construction, simplify the processing technique of flexible PCB, to produce qualification rate high,
The bending of the circuit board made, wind, to fold intensity big, service life is long.
This utility model solves its technical problem and be the technical scheme is that a kind of flexible PCB,
Including flexible circuit board substrate, copper conductor and dielectric film, the Surface Machining of described flexible circuit board substrate has
The guide rail of coupling copper conductor lower shape, described copper conductor is pressed together on the guiding of flexible circuit board substrate
On track, described insulation mould is located on flexible circuit board substrate, and described dielectric film offers corresponding copper
The locating slot of wire shape makes copper conductor exposed on dielectric film top.
Improving further: described copper conductor is circular, described guide rail is semicircle.
The beneficial effects of the utility model are: the flexible PCB contour structures after molding is simple, adds
Work technique is simple, sets the guide rail placing copper conductor on flexible PCB, then on dielectric film
Offer the locating slot corresponding with copper conductor shape, facilitate various electronic devices and components to fit with copper conductor
Connect, simplify the combined process of components and parts and flexible circuit board substrate, and conforming product rate is high.
The pliability utilizing the flexible PCB of this kind of technological forming is good, bending and deformation intensity relatively big, can
It is applicable to the application scenario that some deformation intensity are bigger, such as: the use of wearable device, is difficult to appearance
Flexible PCB and circuit are broken, by folding, the phenomenon even ruptured during using.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of this utility model flexible PCB.
Detailed description of the invention
Presently in connection with embodiment, this utility model is further described.Such as Fig. 1, this utility model is implemented
The open a kind of flexible PCB of example, including flexible circuit board substrate 1, rounded copper wire 2 and dielectric film 3,
The Surface Machining of described flexible circuit board substrate 1 has the semicircle guide rail of coupling copper conductor 2 lower shape
Road 21, described copper conductor 2 is pressed together on the guide rail 21 of flexible circuit board substrate 1, described dielectric film
3 pressures are located on flexible circuit board substrate 1, and described dielectric film 3 offers the location of corresponding copper conductor shape
Groove 31 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), become there is the shape of guide rail by the Surface Machining of flexible circuit board substrate, described guide rail
The shape of the form fit copper conductor in road；
2), by copper conductor strong for pliability, it is placed into flexible circuit with certain elasticity and processing technique
Above the guide rail of base board；
3), on dielectric film, offer the locating slot corresponding with copper conductor shape, allow the copper of respective regions lead
Line is exposed outside, facilitates device to stick or is fabricated to board pads；
4) it is, circuit board by circuit board substrate, wire and dielectric film pressing and forming.
Flexible PCB contour structures after molding is simple, and processing technique is simple, sets on flexible PCB
Place the guide rail of copper conductor, then on dielectric film, offer the locating slot corresponding with copper conductor shape,
Facilitate various electronic devices and components to be fitted and connected with copper conductor, simplify the knot of components and parts and flexible circuit board substrate
Close technique, and conforming product rate is high.The pliability utilizing the flexible PCB of this kind of technological forming is good,
Bending and deformation intensity are relatively big, are applicable to the application scenario that some deformation intensity are bigger, such as: dress and set
Standby use, is difficult to occur that flexible PCB and circuit are broken, by folding, the phenomenon even ruptured during using.
Based on preceding solution, described copper conductor 2 can also be the shape such as oval or square, as long as its
Mesh of the present utility model is achieved that with the form fit of the guide rail 21 on flexible circuit board substrate 1 surface
's.
