Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most identical
Or similar label represents same or similar element or has the element of same or like function.Retouch below with reference to accompanying drawing
The embodiment stated is exemplary, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.
The printing board PCB and terminal proposed according to embodiments of the present invention is described with reference to the accompanying drawings.
The block diagram of Fig. 1 printing board PCB according to an embodiment of the invention.
As it is shown in figure 1, this printing board PCB includes: body 100, first component 110, at least one second component 120
With interference absorber element 130.
Wherein, the first component 110 on body 100 it is arranged on for exporting control signal.It is arranged on body 100
At least one second component 120 be used for receiving control signal.Interference absorber element 130 is arranged at least one second component
In order to absorb the reflection interference that at least one second component 120 produces between 120 and first component 110.Wherein, first
Part 100 can be the process chip of terminal.
Specifically, after printing board PCB powers on, first component 100 (such as, the process chip of terminal) output controls
Signal, when this control signal arrives the second control parts 120, it may occur that " reflection " phenomenon, causes wave distortion, produces
Raw reflecting background.When above-mentioned reflecting background is through interference absorber element 130, can sponge by disturbed absorber element 130,
Thus effectively reduce the reflection interference impact on first component 100, and then first component 100 is effectively ensured can normally work.
It is to be appreciated that first component 110 described in this embodiment and second component 120 are connected with each other by transmission line
Time, it is understood that there may be the discontinuity point of some impedances, will occur when above-mentioned control signal is by these discontinuity poinies " anti-
Penetrate " phenomenon, causes wave distortion, produces reflecting background.Wherein, these discontinuity poinies occur in transmission line and parts more
Junction, i.e. transmission line and the junction of second component 120.
In one embodiment of the invention, as in figure 2 it is shown, interference absorber element 130 can be resistance 10.Wherein, electricity
Resistance 10 can be automatically adjusted the resistance of self according to the signal intensity of the reflection interference between two parts.Specifically, when first
Reflection interference between parts 110 and second component 120 is when resistance 10, and resistance 10 can be according to the signal of reflection interference
Intensity adjusts the size of self resistance automatically, preferably to absorb reflection interference, thus effectively reduces reflection interference to first
The impact of part 110, first component 110 is effectively ensured can normally work.Wherein, the resistance of resistance 10 and reflection interference
Signal intensity is directly proportional.
It addition, resistance 10 can also be the resistance of a fixed resistance value.
It is to be appreciated that when the control signal of first component 100 output is through resistance 10, owing to resistance 10 has one
Fixed resistance, the most above-mentioned control signal has part decay, thus causes this control signal to arrive the second control parts 120
Time, the reflecting background of generation has reduced, and then reduces the impact on first component 100 of this reflecting background.
Further, as in figure 2 it is shown, at least one second component 120 is multiple, multiple second components 120 pass through respectively
Resistance 10 is connected to first component 110.Thus reduce the reflecting background of multiple second component 120 generation to first component 110
Interference.
In one embodiment of the invention, as it is shown on figure 3, at least one second component 120 is multiple, multiple second
Parts 120 are connected in series, and connect resistance in the multiple second components 120 being connected in series between adjacent two second components 120
10.Wherein, multiple second components 120 can be according to anti-interference intensity from arranging away from first component 110 successively to weak by force.
Specifically, if as in figure 2 it is shown, the control signal of first component 110 output flows successively through above-mentioned many by transmission line
Individual second component 120, then this control signal is often when a second component 120, all may produce a reflecting background,
Thus parts above are produced impact (as shown in phantom in Figure 3), and the parts that distance first component 110 is the nearest, institute
The reflection interference being subject to is the biggest, therefore, multiple second components 120 according to anti-interference intensity from strong to weak successively away from first
Part 110 (that is, the parts of output signal) is arranged.
Additionally, the above-mentioned multiple second components 120 being connected in series connect between adjacent two second components 120 resistance 10,
Can effectively absorb reflection interference, it is ensured that each parts can normally work.
In one embodiment of the invention, as shown in Figure 4, at least one second component 120 is many group second components 120,
Often group second component 120 radiates setting to weak to the surrounding of body 100 from strong according to anti-interference intensity.
Printing board PCB according to embodiments of the present invention, outputs a control signal at least one second component at first component
After, at least one second component can produce transmitting interference, now by be arranged at least one second component and first component it
Between interference absorber element absorb at least one second component produce reflection interference, thus effectively prevent at least one second
The reflection interference that parts produce affects first component, and then ensure that first component can normally work.
In order to realize above-described embodiment, the present invention also proposes a kind of terminal, and it includes above-mentioned printing board PCB.Wherein, eventually
End can include mobile phone and panel computer.
The terminal of the embodiment of the present invention, the terminal of the embodiment of the present invention, by above-mentioned printing board PCB, it is possible to effectively reduce
The reflection interference impact on previous parts, thus terminal is effectively ensured and can normally work, improve the reliability of terminal.
