Language concrete meaning in this utility model.
The printed circuit board (PCB) according to this utility model embodiment, i.e. pcb board, this print is described in detail below in conjunction with Fig. 1-Fig. 7
Printed circuit board can be used for mobile terminal, but is not limited to this.
With reference to shown in Fig. 1-Fig. 7, may include that mainboard 1, metal derby according to the printed circuit board (PCB) of this utility model embodiment
2 and tin cream part 3.
Specifically, as it is shown in figure 1, the surface of mainboard 1 can be provided with routing layer 11, the solder mask window of routing layer 11 can be beaten
Open form becomes pad 12, to realize the connection with metal derby 2.
Metal derby 2 can cover the surface of pad 12 at least some of on, metal derby 2 can improve overcurrent energy
Power, and the heat that mainboard 1 produces can utilize metal derby 2 auxiliary heat dissipation for delivery to metal derby 2, accelerates radiating rate, improves
Heat-sinking capability, such that it is able to a certain degree improving stability and the reliability of printed circuit board (PCB).
As shown in Fig. 2-Fig. 7, the periphery of metal derby 2 is along being provided with the breach 21 extending to mainboard 1, and tin cream part 3 is permissible
It is located in breach 21, to weld metal derby 2 and pad 12.It is to say, metal derby 2 and pad 12 are by being located in breach 21
Tin cream part 3 is weldingly connected.Thus, it is possible to make the welding of metal derby 2 more firmly, and tin cream part 3 can enter with auxiliary heat dissipation
And radiating effect can be made more preferable, improve stability and the reliability of printed circuit board (PCB) further.
According to the printed circuit board (PCB) of this utility model embodiment, by forming pad 12 on the routing layer 11 of mainboard 1, will
Metal derby 2 covers on the surface of pad 12, and in the periphery of metal derby 2 along arranging breach 21, tin cream part 3 is located at breach 21
In, such that it is able to utilize metal derby 2 to improve overcurrent capability, and the heat of routing layer 11 can be for delivery to metal derby 2 and stannum
Cream part 3, by metal derby 2 and tin cream part 3 auxiliary heat dissipation, good heat dissipation effect, meanwhile, welds metal derby 2 and weldering by tin cream part 3
Dish 12, it is also possible to improve the fastness of metal derby 2 welding, the stability of printed circuit board (PCB) and reliability high, service life extends.
According to embodiments more of the present utility model, routing layer 11 can include electric power network routing layer and ground wire cabling
Layer, at least one solder mask window in electric power network routing layer and ground wire routing layer is unfolded into pad 12.It is to say, power supply
The solder mask window of network routing layer can be unfolded into pad 12, or, the solder mask window of ground wire routing layer can be unfolded into
Pad 12, then or, the solder mask window of electric power network routing layer and ground wire routing layer can be unfolded into pad 12 simultaneously.By
This, at least one in electric power network routing layer and ground wire routing layer can weld metal derby 2, with improve overcurrent capability and
Radiating effect.
Metal derby 2 can be connected with the pad 12 of electric power network routing layer, and metal derby 2 not with electric power network routing layer
The surface of contact is formed as insulating surfaces.In other words, metal derby 2 is connected with the pad 12 of the routing layer of electric power network, metal derby 2
The part not being connected with pad 12 carries out insulation processing.As such, it is possible to dispelled the heat for electric power network routing layer by metal derby 2, carry
The overcurrent capability of high electric power network, accelerates the charging rate of mobile terminal, and is possible to prevent electric power network and All other routes
Short circuit, improves reliability.
According to embodiments more of the present utility model, as shown in Fig. 2, Fig. 4 and Fig. 6, metal derby 2 can be formed as four limits
Breach 21 can be respectively equipped with, to improve the reliability of metal derby, and in tetragon in shape, and four edges of metal derby 2
The convenient processing of metal derby 2, manufacture difficulty can be reduced, at the same time it can also be improve heat-sinking capability.
As shown in Fig. 2-Fig. 7, each edge of metal derby 2 can be provided with the breach 21 of multiple spaced apart setting, thus
Tin cream part 3 can be set in multiple breach 21, improve the reliability and stability that metal derby 2 welds with mainboard further, with
Time can also improve heat-sinking capability.
Alternatively, the interval b between width a and the breach 21 being adjacent of each breach 21 can meet: a≤b≤
3a, i.e. adjacent distance b between two breach 21 can between breach 21 width and breach 21 width of three times value.
Thus, it is possible to avoid occurring that tin cream part 3 welds the phenomenon of difficulty because being spaced the least between breach 21, it is also possible to prevent because of breach
It is spaced too big and that not prison welding is solid phenomenon between 21, soldering reliability and the stability of metalwork 2 and mainboard 1 can ensured
While reduce difficulty of processing, cost-effective.
According to embodiments more of the present utility model, the bearing of trend of breach 21 can be identical with the thickness direction of metal derby 2,
It is to say, breach 21 can run through the whole thickness of metal derby 2, thus tin cream part 3 can from metal derby 2 away from mainboard 1
Surface run through the surface of metal derby 2 to mainboard 1, metal derby 2 is weldingly connected with pad 12, fastness is good, and when welding,
The consumption of tin cream part 3 is few, can reduce cost, at the same time it can also be utilize the further auxiliary heat dissipation of tin cream part 3, improves printing electricity
The heat-sinking capability of road plate, improves overcurrent capability further.
In an example as described in Fig. 2 and Fig. 3, the cross section of breach 21 can be formed as semicircular arc, processing and manufacturing
Convenient, and highly thermally conductive efficiency can be put forward further, it is ensured that heat radiation good.Certainly, the shape of the cross section of breach 21
Being not limited to this, in another example as described in Fig. 4 and Fig. 5, the cross section of breach 21 is formed as triangle, and such as Fig. 6 and
In example shown in Fig. 7, the cross section of breach 21 is formed as tetragon.In other words, the cross section of breach 21 can be formed as half
One in circular arc, triangle and tetragon.
Further, as shown in Fig. 3, Fig. 5 and Fig. 7, the cross-sectional area of tin cream part 3 can be less than or equal to the transversal of breach 21
Area, tin cream part 3 is at least located at the blind end of breach 21.It is to say, at least some of and closing of breach 21 of tin cream part 3
End is connected, and tin cream part 3 can be contained in breach 21.Thus, being possible not only to improve metal derby 2 can with welding of pad 12
By property and stability, and can make the compact conformation of printed circuit board (PCB) neatly, aesthetic property is preferable.
In certain embodiments, as shown in Figures 6 and 7, breach 21 can be formed as tetragon, two internal edges of tetragon
Angle can be formed as 90 degree of fillets, and tin cream part 3 can be located at 90 degree of fillets, thus convenient welding, and firm welding is good.
In order to improve the aesthetic property of printed circuit board (PCB) further, the edge, periphery of metal derby 2 at least partially can be with mainboard 1
Periphery arrange along alignment, such that it is able to make metal derby 2 and mainboard 1 form a regular entirety so that aesthetic property is more excellent.
