Description
Technical field
Circuit board technology field is the utility model is related to, more particularly to a kind of stretchable FPC.
Background technology
FPC is using polyester film or polyimides as base material, and circuit is formed and manufactured one kind by being etched on copper foil
With height reliability, the printed circuit of excellent flexibility.
Due to FPC can free bend, folding, winding the characteristics of, in terms of FPC is increasingly being applied to move medical treatment at present
Wearable product in, but traditional FPC may only bend and cannot stretch, but some need in use and skin
The motion medical product of skin fitting contact, also requires that it has certain draftability, otherwise makes in addition to the flexural property for needing FPC
Occurring stretching during can cause product to be pulled and can not connect or loose contact, cause product rejection.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of stretchable FPC.
The utility model is to solve the technical scheme that its technical problem uses to be：
A kind of stretchable FPC, including insulated substrate, the metallic circuit layer in insulated substrate, the metallic circuit
Insulating protective layer is provided with layer, the insulating protective layer includes several collets, has subdivided gap between collets, several
Collets on insulating protective layer in being disposed to extend to form stretch zones.
Further, the subdivided gap takes the shape of the letter U or half-circle-arc shape.
Further, the insulating protective layer is disposed to extend the stretch zones formed by several collets respectively including multiple.
Further, the stretch zones include several regions of longitudinal stretch or regions of lateral stretch be arrangeding in parallel,
In other embodiments, the stretch zones include several regions of longitudinal stretch and regions of lateral stretch, the regions of longitudinal stretch
With the intersecting setting in regions of lateral stretch.
Further, the material of the insulated substrate is PET film or PI films；The metallic circuit layer is copper foil circuit layer；
The material of the insulating protective layer is PET film or welding resistance green oil.
Above-mentioned stretchable FPC can be made by following manufacture craft, and the technique comprises the following steps：A. sawing sheet；B. bore
Hole；C. dry film is pasted；D. contraposition exposure；E. develop, etch, demoulding, line pattern is made；F. using pasting epiphragma or welding resistance
Method makes insulating protective layer；G. in insulating protective layer uplifting window, the compartment between several collets and collets is cut out
Gap.Specifically, in step d, the exposure aligning uses CCD para-position；In step g, protected using the method for laser cutting in insulation
Sheath uplifting window.
The beneficial effects of the utility model are：FPC provided by the utility model is provided with stretch zones, the stretch zones by
Several collets are formed, and separation gap is set between collets, and separation gap causes FPC to have draftability.It is of the present utility model
Stretchable FPC avoids product from being pulled in use and can not connected or loose contact suitable for medical product.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the structural representation of Section A-A in Fig. 1.
Embodiment
The utility model is described further below in conjunction with accompanying drawing and example.
As depicted in figs. 1 and 2, a kind of stretchable FPC of the present utility model, including insulated substrate 1, positioned at insulated substrate
Metallic circuit layer 2 on 1, is provided with insulating protective layer 3 on the metallic circuit layer 2, the insulating protective layer 3 include it is several absolutely
Edge block 5, has subdivided gap 4 between collets 5, and several collets 5 on insulating protective layer 3 in being disposed to extend to form drawing zone
Domain.The utility model on FPC by setting subdivided gap 4 to make it have draftability.
The shape of the subdivided gap 4 preferably uses U-shaped or half-circle-arc shape, between splitting compared in general linear
The subdivided gap 4 of gap, U-shaped or half-circle-arc shape is due to the design feature with semi-surrounding so that and extension area is relatively large,
Thus draftability can be stronger.
Multiple stretch zones can be set in the insulating protective layer 3, and each stretch zones extend cloth by several collets 5 respectively
Put what is formed, as shown in figure 1, the FPC of the present embodiment has a regions of lateral stretch 7 and six regions of longitudinal stretch 6, and
And the intersecting setting in the regions of lateral stretch 7 and regions of longitudinal stretch 6 so that the FPC of the present embodiment is in its length direction and width
Degree is respectively provided with certain draftability on direction.
In other embodiments, the stretch zones can only set several parallel regions of lateral stretch 7 or longitudinal direction to draw
Region 6 is stretched, makes FPC that only there is draftability on its length direction or width.
The material of the insulated substrate 1 can be PET film or PI films；The metallic circuit layer 2 is copper foil circuit layer；Institute
The material for stating insulating protective layer 3 can be PET film or welding resistance green oil.
Above-mentioned stretchable FPC can be made by following manufacture craft, and the technique comprises the following steps：A. sawing sheet；B. bore
Hole；C. dry film is pasted；D. contraposition exposure；E. develop, etch, demoulding, line pattern is made；F. using pasting epiphragma or welding resistance
Method makes insulating protective layer 3；G. in the uplifting window of insulating protective layer 3, cut out between several collets 5 and collets 55
Separation gap 4.
In step d, the exposure aligning uses CCD para-position.
In step g, using the method for laser cutting in the uplifting window of insulating protective layer 3.
Certainly, it is to be also not limited to the example above to limitation of the present utility model, the utility model that described above, which is not,
The variations, modifications, additions or substitutions that those skilled in the art are made in essential scope of the present utility model, also should
Belong to the scope of protection of the utility model.
