It is good, final products are formed by compacting with the cover film for having mechanical protection and good electrical insulation performance concurrently.Flexible circuit board one
As be used in the closed space such as mobile phone, tablet computer, when especially applying in notebook or clamshell phone, need regular
Overturning, it is therefore desirable to improve the intensity and suppleness of flexible PCB.
Traditional FPC designs and manufacturing field, when the FPC substrate sides of flexible circuit board have electronic device or structure device
It, can be at the back side of FPC substrates by joint adhesive lamination reinforcement piece, to increase FPC hardness and planarization, convenient for welding when part.Mesh
The preceding supporting material mainly used has：Polyimides (Polyimide, initialism PI), epoxy glass cloth laminated board (FR 4)
Or the metal reinforcement of steel disc, aluminium flake etc., but mainly plane supporting material.
In the flexible PCB of the prior art, as shown in Figure 1, the back side of flexible PCB includes reinforcing member 10, the benefit
The position of strong part 10 and pad is corresponding, which mainly passes through employee's visual inspection flexible electrical in this configuration for reinforcement
Whether the reinforcing member on the plate of road lacks, therefore is easy that missing inspection, efficiency are low, and can not avoid the FPC substandard products streams of leakage reinforcing part
Go out, thus defect ware rate is high.In addition, hand inspection is of high cost.
Therefore, it is necessary to provide a kind of new flexible PCB.
【Utility model content】
Whether lacked in order to efficient detection reinforcing member, reduction in the numbers of seconds, and cost will not be increased, the utility model carries
Supplied a kind of flexible PCB comprising be arranged the first surface of the flexible PCB conductive sheet, setting with it is described
The reinforcing member of the opposite second surface of first surface, the reinforcing member include at least two O/S measuring points, and the reinforcing member setting exists
The material of position corresponding with the conductive sheet, the reinforcing member is metal material.
As an improvement the conductive sheet is pad.
As an improvement the O/S measuring points are used as electrical measurement interconnecting piece, which is used to connect with electrical measurement tool
It connects.
As an improvement the reinforcing member is steel disc.
As an improvement the outer profile boundary of the reinforcing member and the profile boundaries of the flexible PCB are separated by centainly
Distance.
The utility model has the beneficial effects that：The flexible PCB of the utility model is additionally arranged O/S measuring points on reinforcing member,
By electrical measurement can efficient detection reinforcing member whether lack, reduction in the numbers of seconds, additionally, due to reinforcing member and flexible PCB circuit
Electrical measurement together need not increase extra cost, reduce cost.
【Description of the drawings】
Fig. 1 is the structural schematic diagram of the second surface of the flexible PCB of the prior art；
Fig. 2 is the structural schematic diagram of the second surface of the flexible PCB of the utility model.
【Specific implementation mode】
The utility model is described in further detail below by specific implementation mode combination attached drawing, so as to more preferably
Ground understands the advantages of the embodiment of the utility model and its various aspects.Below in an example, embodiment party in detail below is provided
The purpose of formula is easy for becoming apparent from thorough explanation to the content of the utility model, rather than limitations of the present invention.
In the present invention, it is front, i.e. first surface with the surface of the setting conductive sheet of flexible PCB and wiring,
And the surface opposite with the front of flexible PCB is the back side, i.e. second surface.
With reference to Fig. 2, the utility model provides a kind of flexible PCB, which includes being located at flexible PCB just
The conductive sheet in face, electroplate lead wire, the reinforcing member 10 for being set to flexible circuit back and two be arranged on the reinforcing member
O/S measuring points 11, the conductive sheet are electrically connected with interfacing part, and conductive sheet is, for example, that pad, golden finger etc. are led in the present embodiment
Electric piece is mainly pad, and the material of reinforcing member is metal material, and O/S measuring points 11 are two, above-mentioned to be merely to illustrate, and cannot be understood
At limitations of the present invention.
Specifically, the front of the flexible PCB of the utility model, i.e. first surface includes electroplate lead wire and electroplate lead wire
The pad of connection, wherein the pad is electrically connected with the interfacing part of such as metal clips etc..But above-mentioned these are merely to illustrate,
Quantity and position for pad can be determined according to circuit board wiring rule.
In addition, the back side of the flexible PCB of the utility model, i.e. second surface include benefit corresponding with the position of pad
Strong part 10, is all provided with that there are two O/S measuring points on each reinforcing member 10, wherein the material of reinforcing member 10 is metal material, the metal material
Material for example, steel disc, copper sheet, aluminium flake etc., in the present embodiment, preferably steel disc；O/S measuring points are used as electrical measurement interconnecting piece, the electricity
Interconnecting piece is, for example, electrical measurement hole etc., and the electrical measurement hole with the electrical measurement tool of such as electroprobe etc. for connecting to carry out electrical measurement, at this
In embodiment, electrical measurement interconnecting piece is circle, it is also possible to be other shapes；Reinforcing member 10 can increase the intensity of conductive sheet
And hardness, thus, it is possible to ensure the intensity requirement of welding disking area.In addition, outer profile boundary and the flexible PCB of reinforcing member 10
Profile boundaries line is separated by a distance.In the present embodiment, the shape of reinforcing member 10 is rectangle, and the corner of rectangle is that circle falls
Angle, but not limited to this, can also be the other shapes such as square, polygon, circle.
In the present embodiment, detect whether reinforcing member 10 lacks by electrical measurement mode, and together with flexible PCB
Electrical measurement need not increase extra cost, reduce cost.When being detected there are two the reinforcing member of O/S measuring points to having, if
Two test open circuits, judgement reinforcing member leakage patch；If two measuring point short circuits, judgement reinforcing member does not leak patch.It is short in two measuring points
In the case of road, then flexible PCB is certified products.Due to adding O/S measuring points on reinforcing member, can efficiently be examined by electrical measurement
Survey whether reinforcing member lacks, reduction in the numbers of seconds.
Compared with prior art, the flexible PCB of the utility model is additionally arranged O/S measuring points on reinforcing member, passes through electrical measurement
Can efficient detection reinforcing member whether lack, reduction in the numbers of seconds, additionally, due to reinforcing member electrical measurement together with flexible PCB circuit,
Extra cost need not be increased, reduce cost.
