Abstract
The utility model discloses a flexible circuit board. The flexible circuit board comprises a copper foil layer, protective layers and golden fingers, wherein the protective layers comprise a first protective layer and a second protective layer, and the copper foil layer is arranged between the first protective layer and the second protective layer in a bonding manner; and the golden fingers are connected to the both ends of the copper foil layer, and exposed out of the copper foil layer and the protective layers. The flexible circuit board disclosed by the utility model can be directly welded with an external electric appliance by the golden fingers without the need of additionally welding golden fingers on the flexible circuit board, and the golden fingers are not easy to fall off, so that the circuit board is higher in the performance of connection with the external electric appliance.
Description
Technical field
The utility model belongs to electronic technology field, relates in particular a kind of flexible circuit board.
Background technology
Along with developing rapidly of information age, more and more higher for the requirement of integrated electronic industry.Particularly to the requirement of the performance of flexible circuit board.Flexible circuit board on market, when connecting the external circuit connector, need to be welded in addition golden finger, then be connected with the external circuit connector on flexible circuit board, golden finger is easily bent and cause the golden finger out-of-flatness, or even fracture, thereby affect the installation of flexible circuit board, the increase cost.
The utility model content
In order to address the above problem, the utility model provides a kind of flexible circuit board.
According to an aspect of the present utility model, provide a kind of flexible circuit board.It comprises copper foil layer, protective layer and golden finger, and protective layer is provided with the first protective layer and the second protective layer, and copper foil layer is attached between the first protective layer and the second protective layer.The copper foil layer two ends all are connected with golden finger, and golden finger is exposed outside copper foil layer and protective layer, are convenient to flexible circuit board and directly weld with outside electrical equipment.
In some embodiments, copper foil layer thickness, between 0.15 millimeter to 0.2 millimeter, makes copper foil layer be difficult for even fracture of bending distortion.
In some embodiments; bonding by epoxy glue between copper foil layer and protective layer; because the feature that epoxy glue has good stability, easily solidifies, adhesion is strong and shrinkage is low, can make protective layer and copper foil layer fully bonding, prevent from producing bubble between protective layer and copper foil layer.
Flexible circuit board described in the utility model can directly be welded to connect with outside electrical equipment by golden finger, need to not weld in addition golden finger on flexible circuit board, does not also affect the switching performance of wiring board and outside electrical equipment.
The accompanying drawing explanation
Fig. 1 is the cross-sectional view of the flexible circuit board of the utility model one execution mode;
Fig. 2 is the structural representation of the flexible circuit board of the utility model one execution mode.
Embodiment
Below in conjunction with embodiment, the utility model is further described.
As shown in Figure 1, the flexible circuit board of an execution mode described in the utility model, it comprises copper foil layer 1, protective layer and golden finger 2, and protective layer is provided with the first protective layer 3 and the second protective layer 4, and copper foil layer 1 is attached between the first protective layer 3 and the second protective layer 4.During concrete enforcement; bonding by epoxy glue between copper foil layer 1 and protective layer; because the feature that epoxy glue has good stability, easily solidifies, adhesion is strong and shrinkage is low; can make protective layer and copper foil layer 1 fully bonding; prevent from producing bubble between protective layer and copper foil layer 1, if produce bubble, conductive materials is easily arranged in bubble; will make like this copper foil layer 1 short circuit, flexible circuit board is scrapped.
Copper foil layer 1 two ends all are connected with golden finger 2, and golden finger 2 is exposed outside copper foil layer 1 and protective layer, are convenient to flexible circuit board and directly weld with outside electrical equipment.
When implementing the utility model, the thickness of copper foil layer 1, between 0.15 millimeter to 0.2 millimeter, makes copper foil layer 1 be difficult for even fracture of bending distortion.
Flexible circuit board described in the utility model can directly be welded to connect with outside electrical equipment by golden finger 2, need to not weld in addition golden finger 2 on flexible circuit board, makes golden finger 2 difficult drop-offs, makes the switching performance of wiring board and outside electrical equipment more.During concrete enforcement, for preventing that golden finger 2 from being fractureed, can increase the thickness of golden finger 2, when making golden finger 2 and the welding of outside electrical equipment, golden finger can bending, can not rupture.
Above-described is only execution modes more of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from creation design of the present utility model; can also make other distortion and improvement, these all belong to protection range of the present utility model.
