Description
Technical field
The utility model relates to flexible circuit board, is specifically related to a kind of flexible circuit board of touch-screen.
Background technology
In touch-screen procedure for producing, flexible circuit board FPC needs to bind together with ITO FILM and ITO GLASS, the technique of two-sided pressing is that pad that FPC binds district has two conducting surfaces will be upward, there are two conducting surfaces will be down, but golden finger part is connected with mainboard only has a face, so need to arrange via on FPC, the circuit on FPC is forwarded to the same face of golden finger.
Via is CNC through hole on baseplate material, then copper-plating technique is passed through, the copper of one deck about 10um is adhered at hole wall, but, the bad problem that the flexible circuit board of touch-screen often has via to open a way, if via position is in assembling bending region, unavoidably in turnover and assembling process, capital is subject to the external force bending of both forward and reverse directions, and because of the limitation of technique, the copper facing thickness of whole via hole wall there will be uneven situation, fracture may be there is in thinner layers of copper in bending process, product is caused to occur the dysfunction phenomenon of open circuit, and then cause touch-screen to lose efficacy.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is the flexible circuit board of a kind of touch-screen providing via to be effectively protected.
The purpose of this utility model adopts following technical scheme to realize:
A kind of flexible circuit board of touch-screen, comprise the first coverlay, adhesive linkage, the first copper foil layer, substrate and the second copper foil layer that stack gradually, first copper foil layer and the second copper foil layer are formed with the golden finger area exposed respectively, this golden finger area is used as the plug of external receptacle assembling, run through between two golden finger area and have via, via inwall is coated with layers of copper, and the aperture, two ends of via is pasted with the second coverlay, wherein the outside of a golden finger area is pasted with reinforcing chip, and this reinforcing chip covers via and golden finger area.
Preferably, the aperture of described via is 0.1mm, and the thickness of described second coverlay is 1mil, and the thickness of described layers of copper is 10 μm, and described golden finger area is coated with Gold plated Layer, and this plated thickness is 3 ~ 5 μm, and the thickness of described reinforcing chip is 0.2mm.
Compared to existing technology, the beneficial effects of the utility model are:
Of the present utility model under the prerequisite not increasing material and processing cost; make via can under the protection of reinforcing chip; the destruction from extraneous folding force can not be subject to; golden finger area can be used as plug again simultaneously; can guarantee that after dispatching from the factory touch-screen connects normal, and easy to connect, in conjunction with the protection of the second coverlay; can not be partially thin because of via copper facing, and after final assembly, there is function hidden danger.
Accompanying drawing explanation
Fig. 1 is the structural representation in the flexible circuit board front of the utility model touch-screen;
Fig. 2 is the structural representation of the flexible circuit board side of the utility model touch-screen;
Fig. 3 is the structural representation of the flexible circuit board reverse side of the utility model touch-screen.
In figure: 1, the first coverlay; 2, adhesive linkage; 3, the first copper foil layer; 4, substrate; 5, the second copper foil layer; 6, golden finger area; 7, via; 8, reinforcing chip.
Embodiment
The flexible circuit board of a kind of touch-screen as shown in Fig. 1 ~ 3, comprise the first coverlay 1 stacked gradually, adhesive linkage 2, first copper foil layer 3, substrate 4 and the second copper foil layer 5, first copper foil layer 3 and the second copper foil layer 5 are formed with the golden finger area 6 exposed respectively, this golden finger area 6 is used as the plug of external receptacle assembling, run through between two golden finger area 6 and have via 7, via 7 inwall is coated with layers of copper (not shown), and the aperture, two ends of via 7 is pasted with the second coverlay (not shown), wherein the outside of a golden finger area 6 is pasted with reinforcing chip 8, this reinforcing chip 8 covers via 7 and golden finger area 6.
Under the prerequisite not increasing material and processing cost; make via 7 can under the protection of reinforcing chip 8; the destruction from extraneous folding force can not be subject to; golden finger area 6 can be used as plug again simultaneously; can guarantee that after dispatching from the factory touch-screen connects normal, and easy to connect, in conjunction with the protection of the second coverlay; can not be partially thin because of via 7 copper facing, and after final assembly, there is function hidden danger.Wherein, the first copper foil layer 3 and the second copper foil layer 5 are that two-sided 0.5oz is without rubber calendering copper.First coverlay 1 and the second coverlay are PI film, and the first coverlay 1 of attaching and the second coverlay can prevent surface damage.
Particularly, the aperture of the via 7 of this example is 0.1mm, and the thickness of described second coverlay is 1mil, and the thickness of described layers of copper is 10 μm, and described golden finger area 6 is coated with Gold plated Layer, and this plated thickness is 3 ~ 5 μm, and the thickness of described reinforcing chip 8 is 0.2mm.
Preferably, when reinforcing chip 8 length exceedes golden finger area 6 conducting surface 2mm, via 7 just can design in the coverage of reinforcing chip 8.The effect of reinforcing chip 8 is exactly ensure that this flexible circuit board is assembled stable at the connector body with mainboard; conveniently operator assembling socket; its thickness reaches 0.3mm; larger than flexible circuit board 0.1mm thickness; to ensure larger intensity; and can not be bent easily, the hidden danger that the defect overcoming copper-plating technique causes, play the available protecting effect to via 7.
Above-mentioned execution mode is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
