Abstract
The utility model discloses a double-insurance flexible thin-film circuit which relates to the technical field of electronic manufacturing. The double-insurance flexible thin-film circuit comprises an upper circuit, an insulating layer and a lower circuit which are successively adhibited. The upper circuit is provided with a first wire outlet terminal. The lower circuit is provided with a second wire outlet terminal which corresponds with the first wire outlet terminal. Anisotropic conductive adhesive is arranged between the first wire outlet terminal and the second wire outlet terminal for conducting the upper circuit and the lower circuit. The upper circuit further comprises an upper insurance circuit and an upper insurance contact point which are connected with the first wire outlet terminal in parallel. The lower circuit further comprises a lower insurance circuit and a lower insurance contact point which are connected with the second wire outlet terminal in parallel. The upper insurance contact point is fixedly connected with the lower insurance contact point. When inferior contact between the wire outlet terminal and the anisotropic conductive adhesive occurs, the flexible thin-film circuit can operate normally. The double-insurance flexible thin-film circuit has higher reliability.
Description
Technical field
The utility model relates to the electronic manufacturing technology field, particularly a kind of dual fail-safe fexible film circuit.
Background technology
The bridging type fexible film circuit that uses in keyboard is to be fitted and form successively by upper circuit, insulating barrier and lower circuit, upper circuit and lower circuit are provided with respectively the outlet terminal of mutual correspondence, the outlet terminal of upper and lower circuit connects with anisotropic conductive, makes circuit and the lower circuit can conducting.It is higher that existing bridging type fexible film circuit and folded thin film circuit are compared reliability, but when keyboard service time is long or at the operational environment too dry, in the too high situation of temperature, still easily come in contact badly between anisotropic conductive and outlet terminal, this has affected user's experience.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is: how to improve the functional reliability of bridging type fexible film circuit, even make it, also can keep long working stability under the environment of drying, high temperature.
(2) technical scheme

Wherein, the described contact point of insuring is that the hot pressing pressing connects with being connected the connected mode of lower insurance contact point.
Wherein, the material of described circuit is the silver slurry.
(3) beneficial effect
Fexible film circuit of the present utility model has been set up the insurance circuit in parallel with outlet terminal on the basis of bridging type fexible film circuit, when outlet terminal and anisotropic conductive loose contact, this fexible film circuit also can work, and has improved the reliability of thin film circuit.
Description of drawings
Fig. 1 is the structural representation of circuit on fexible film circuit of the present utility model.
Fig. 2 is the structural representation of circuit under fexible film circuit of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Fexible film circuit of the present utility model comprises: upper circuit 2, insulating barrier and the lower circuit 1 of fitting successively.
As depicted in figs. 1 and 2, upper circuit 2 is laid with contact point 6 and circuit 7 in the side near insulating barrier respectively with lower circuit 1, upper circuit 2 is provided with the first outlet terminal 3, lower circuit 1 is provided with the second outlet terminal 4, the first outlet terminal 3 is mutually corresponding with the second outlet terminal 4, and between be provided with anisotropic conductive 5, anisotropic conductive 5 can be realized vertical conducting (i.e. the first outlet terminal 3 and the second outlet terminal 4 conductings), and laterally not conducting, the purpose of doing like this is for circuit in conducting 2 and lower circuit 1.
Upper circuit 2 also comprises insure circuit 9 and the insure contact point 11 in parallel with the first outlet terminal 3, lower circuit 1 also comprises the lower insurance circuit 8 in parallel with the second outlet terminal 4 and lower insurance contact point 10, the contact point 11 of insuring is fixedly connected with lower insurance contact point 10, to form a complete insurance circuit.
Preferably, insure and connect for the hot pressing pressing between contact point 11 and lower insurance contact point 10.
Preferably, the material of circuit 7 is the silver slurry.
When the loose contact of the contact point 11 of insuring, lower insurance contact point 10 and anisotropic conductive 5, insurance circuit can continue upper circuit 2 and lower circuit 1 conducting, makes the reliability of thin film circuit improve.
Above execution mode only is used for explanation the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that do not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
