Abstract
The utility model discloses a kind of flexible and hard combined circuit boards, including mounting plate, the mounting plate is fixed on the workbench of sewing machine, movable plate is installed on the mounting plate, the movable plate is equipped with axis hole and connecting shaft, several line plates with holes are connected in the connecting shaft, line plate can rotate on movable plate around connecting shaft；Using filling epoxide-resin glue in fastening notch, and secondary smearing fastening glue effectively avoids the hard contact between hard circuit board and flexible circuit board, while eliminating the concentrated stress of soft hard circuit board contact position, the fixing for increasing connection, improves service life.
Description
Technical field
The utility model relates to a kind of wiring board, in particular to a kind of flexible and hard combined circuit board.
Background technique
Flexible and hard combined circuit board is flexible circuit board and rigid wiring board by processes such as pressings, by related process requirement group
It is combined, the wiring board with FPC characteristic and PCB characteristic of formation.With light-weight, small in size, three-dimensional space can be free
The advantages that being bent, be flexible, folding；But flexible circuit board and hard circuit board binding site are often not connected firmly, and are easy curved
Fracture the problems such as splitting.
Utility model content
The purpose of the utility model is to provide one kind to be connected firmly, the anti-flexible and hard combined circuit board to fracture.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of flexible and hard combined circuit board, including flexible circuit board described in flexible circuit board and hard circuit board and rigid circuit
Plate is bonded together by anisotropic conductive film, it is characterized in that: the side of the hard circuit board and flexible circuit board adhesive surface
Edge position is equipped with fastening notch, fills epoxide-resin glue in the fastening notch.
Avoid the boundary of hard circuit board direct by filling up epoxide-resin glue in fastening notch using above-mentioned setting
It is contacted with flexible circuit board, thus avoid fractureing since flexible battery plate is repeatedly bent with hard circuit board border collision, ring
Oxygen resin glue not only acts as the effect of a fastening, equally also acts as a buffer function.
Further, the cross sectional shape of the fastening notch is rectangle.
Likewise, the cross sectional shape of the fastening notch is triangle.
Further, the outside of the fastening notch is also coated with fastening glue, and the fastening glue is similarly epoxide-resin glue；Tightly
Solid glue is to be smeared after epoxy resin adhesive curing in fastening notch again, be coated in smear the epoxide-resin glue that is cured with it is soft
The edge positions of property circuit board contacts, can effectively remove concentrated stress, further increase connectivity robustness.
Further, the hard circuit board is equipped with several through-holes；Wherein through-hole makees hard circuit board and flexibility
The location hole of circuit board connection.
In conclusion the utility model has the following beneficial effects: using epoxide-resin glue is filled in fastening notch, and
Secondary smearing fastening glue effectively avoids the hard contact between hard circuit board and flexible circuit board, while eliminating soft hard electricity
The concentrated stress of road plate contact position, increases the fixing of connection, improves service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment one；
Fig. 2 is the structural schematic diagram of embodiment two.
In figure, 1, flexible circuit board；2, hard circuit board；3, fastening notch；4, through-hole；5, chamfering is connected.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment one: as shown in Figure 1, including flexible circuit board 1 and hardness described in flexible circuit board 1 and hard circuit board 2
Circuit board 2 is bonded together by anisotropic conductive film, while being made between flexible circuit board 1 and hard circuit board 2 electrically
The marginal position of connection, the hard circuit board 2 and 1 adhesive surface of flexible circuit board is equipped with fastening notch 3, the fastening notch 3
Inside fill epoxide-resin glue；Wherein the cross sectional shape of the fastening notch 3 is rectangle, and the outside of the fastening notch 3 is also coated with
Fastening glue 5, the fastening glue 5 are similarly epoxide-resin glue, and wherein fastening glue 5 is the epoxide-resin glue inside fastening notch 3
It is smeared up again after solidification, is coated in the edge positions that the epoxide-resin glue smeared and be cured is contacted with flexible circuit board 1, it can
Effectively to remove concentrated stress, connectivity robustness is further increased；The hard circuit board 2 is equipped with several through-holes 4, wherein
Through-hole 4 avoids route and component locations on hard circuit board 2, can be used as hard circuit board 2 and flexible circuit board 1 bonds
Location hole, while the heat dissipation on wiring board can be increased.
Embodiment two: as shown in Fig. 2, embodiment two and the difference of embodiment one are, the section shape of the fastening notch 3
Shape is triangle, remaining structure is all the same, and the section of fastening notch 3 uses triangle, facilitates smearing epoxide-resin glue, and add
Work is convenient, not will increase excessive process.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
