Abstract
The utility model provides a kind of FPC with corner circuit, and comprise plate body, plate body is provided with land, it is characterized in that: be provided with corner circuit in the land on described plate body, and described corner circuit interior angle place is also provided with protection copper.After adopting said structure, the local product inside of all interior angles of corner circuit adds protection copper, namely increases anti-tear line in the easy tear place of FPC, ruptures when bending to prevent FPC.Realize under the prerequisite not affecting the function of product own, decrease product in use, repeatedly during bending, fracture and producing is scrapped, thus improves the life-span of product, improves the quality of products, improve product commercially unexpectedly strive power.
Description
Technical field
The utility model relates to circuit board, particularly a kind of FPC plate with corner circuit.
Background technology
At some in the wiring boards such as mobile phone, a lot of use FPC plate, and bending property is good exactly to use one of FPC product large feature.The FPC product that need repeatedly bend, the shape due to FPC product is diversified, and due to the division reason of circuit, FPC product has the place of many circuit angle interior angles.FPC through repeatedly bending, interior angle easy fracture.FPC life of product is reduced.
Summary of the invention
For solving the problem; in order to ensure that FPC interior angle ruptures; improve the quality of products, reduce scrapping of sheet material, reduce costs; improve FPC and use pressure life; this reality is novel provides a kind of FPC with corner circuit, and comprise plate body, plate body is provided with land; it is characterized in that: be provided with corner circuit in the land on described plate body, described corner circuit interior angle place is also provided with protection copper.
Described protection copper shape is arc, corresponding with the interior angle of corner circuit.
Described protection copper is less than 0.2mm from angular distance in corner circuit.
The live width of described protection copper is for being greater than 0.2mm.
After adopting said structure, the local product inside of all interior angles of corner circuit adds protection copper, namely increases anti-tear line in the easy tear place of FPC, ruptures when bending to prevent FPC.Realize under the prerequisite not affecting the function of product own, decrease product in use, repeatedly during bending, fracture and producing is scrapped, thus improves the life-span of product, improves the quality of products, improve product commercially unexpectedly strive power.
The utility model structure is simple, practical, effectively improves the quality of products, and improves useful life, improves product competitiveness commercially.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Be denoted as in figure:
1 plate body, 2 land, 3 corner circuits, 4 protection copper
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is described in further detail, but does not form any restriction of the present utility model.
As shown in Figure 1, a kind of FPC with corner circuit, comprises plate body 1, and plate body 1 is provided with land 2, it is characterized in that: be provided with corner circuit 3 in the land 2 on described plate body 1, and described corner circuit 3 interior angle place is also provided with protection copper 4.
As the further improvement of technology, described protection copper 4 shape is arc, corresponding with the interior angle of corner circuit 3, effectively realizes protective effect.
As the further improvement of technology, described protection copper 4 is less than 0.2mm from angular distance in corner circuit 3, and the live width of described protection copper 4 is for being greater than 0.2mm, and realizing easy tear place increases hardness, effectively prevents from tearing.
After adopting said structure, the local product inside of all interior angles of corner circuit adds protection copper, namely increases anti-tear line in the easy tear place of FPC, ruptures when bending to prevent FPC.Realize under the prerequisite not affecting the function of product own, decrease product in use, repeatedly during bending, fracture and producing is scrapped, thus improves the life-span of product, improves the quality of products, improve product commercially unexpectedly strive power.
The utility model structure is simple, practical, effectively improves the quality of products, and improves useful life, improves product competitiveness commercially.
