Abstract
The utility model discloses a flexible printed circuit board, golden finger (2) that include basement (1), cover membrane (3) and locate the FPC joining region, it is equipped with window (5) to cover membrane (3), the line terminal of walking of golden finger (2) is equipped with golden finger extension (4), and golden finger extension (4) are located the below that covers membrane (3), window (5) the line terminal was walked to the golden finger one side for the wave, make the golden finger walk line terminal and extension in handing -over department lining epiphragma (3) cover, through setting up the extension, reduce the golden finger and in the cracked possibility of termination department, simultaneously, adopted corrugated windowing, messenger's golden finger is walked the line terminal and is covered at handing -over department lining epiphragma with the extension, plays good guard action, avoids the FPC golden finger phenomenon of splitting, coming off to appear, FPC connection zone's edge remains the cover membrane, has increased the thickness at FPC edge for FPC is at the cracked possibility greatly reduced in edge.
Description
Technical field
The utility model relates to a kind of flexible print circuit board.
Background technology
FPC flexible print circuit board (FlexiblePrintedCircuitBoard is called for short FPC) uses polyimide film to be base material, the wiring board sheet material made together with Copper Foil pressing.It has the many advantages such as excellent bending resistance folding endurance, weldability, ultra-thin volume and cost be low.
FPC is generally arranged golden finger and realize the connection with main circuit board, it is use connector to connect that current connected mode mainly contains two kinds: one, although this kind of method is easy to connect, the shortcomings such as the space needed for existence connects is large, grafting is unstable, use cost is high; Two is use the mode of welding to connect, but will weld, then need to remove coverlay, spill golden finger and form pad, the material of golden finger is generally Copper Foil, because golden finger is very thin, and the ductility of Copper Foil neither be fine, make the ability of FPC welding position resistance to stress very low, be easy to occur fractureing in production and Transportation Engineering, even the problem such as dactylolysis.
Utility model content
The purpose of this utility model is to provide a kind of flexible print circuit board, and this wiring board can strengthen the resistance to stress ability of FPC welding position, avoids the phenomenon that FPC golden finger occurs fracture, comes off.
The utility model solves the technical scheme that its technical problem adopts:
A kind of flexible print circuit board, comprise substrate, coverlay and be located at the golden finger of FPC bonding pad, described coverlay is provided with windows, and the line end of walking of described golden finger is provided with golden finger extension, and golden finger extension site is in the below of coverlay; Described to window in the side that golden finger walks line end be waveform, makes golden finger walk line end and extension and be coated to epiphragma in junction and cover.
Further, the length of described golden finger extension is 3 ~ 5mm.
Further, described in the sidepiece edge of windowing inside contract 1 ~ 2mm, make the side margins of FPC bonding pad retain the coverlay of 1 ~ 2mm.
The beneficial effects of the utility model are, by arranging extension, reduce the possibility that golden finger ruptures at termination place, simultaneously, adopt corrugated windowing, make golden finger walk line end and extension to be coated to epiphragma in junction and to cover, play a good protection, avoid the phenomenon that FPC golden finger occurs fracture, comes off; The edge of FPC join domain retains coverlay, adds the thickness at FPC edge, FPC is reduced greatly in the possibility of edge breaks.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of flexible print circuit board, and comprise substrate 1, coverlay 3 and the golden finger 2 being located at FPC bonding pad, described coverlay 3 is provided with windows 5, the line end of walking of described golden finger 2 is provided with golden finger extension 4, and golden finger extension 4 is positioned at the below of coverlay 3; Described windowing 5 is waveform in the side that golden finger walks line end, makes golden finger walk line end and extension and is coated to epiphragma 3 in junction and covers; Preferably, the length of golden finger extension 4 is 3 ~ 5mm, and golden finger 2 and golden finger extension 4 are integrated.Described window 5 sidepiece edge inside contract 1 ~ 2mm, make the side margins of FPC bonding pad retain the coverlay of 1 ~ 2mm.
By arranging extension, reduce the possibility that golden finger ruptures at termination place, simultaneously, adopt corrugated windowing, make golden finger walk line end and extension to be coated to epiphragma in junction and to cover, play a good protection, avoid the phenomenon that FPC golden finger occurs fracture, comes off; The edge of FPC join domain retains coverlay, adds the thickness at FPC edge, FPC is reduced greatly in the possibility of edge breaks.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to the utility model; Any those of ordinary skill in the art, do not departing under technical solutions of the utility model ambit, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Therefore; every content not departing from technical solutions of the utility model; according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent replacement, equivalence change and modification, all still belong in the scope of technical solutions of the utility model protection.
