Below in conjunction with Description of Drawings printed circuit board (PCB) according to embodiments of the present invention.
Fig. 1 is the structure chart of printed circuit board (PCB) according to an embodiment of the invention.
As shown in figure 1, printed circuit board (PCB) according to an embodiment of the invention（Pcb board）100, including：Input and output connect
Mouth 110, communication device 120 and (PCC) power 130.
Specifically, with the ground Network Isolation of the first default spacing between the adjacent signals in input/output interface 110, its
In, the first default spacing can be 10mil.It is understood that the first default spacing not limited to this, can also for other away from
From such as 9mil or 12mil etc. will not be repeated here.
Input/output interface 110 is mainly used in transmitting sensitive signal, these sensitive signals due to each other away from very little, mutually
Between can produce signal cross-talk, so as to influence the normal transmission of signal, thus by between adjacent signals with the ground of the first default spacing
, there is crosstalk in Network Isolation, it is ensured that the correct transmission of signal between can avoiding signal.Have by ground network and signal is shielded
The effect of protection is covered, the antijamming capability of signal itself is not only increased, it is to avoid the generation of crosstalk between signal, while also by itself
The radiation signal of generation is preferably minimized, and is that adjacent devices have good protective effect to device itself.
Communication device 120 is with the ground Network Isolation of the second default spacing.Wherein, the second default spacing can be 7mil.Can
To understand, the second default spacing not limited to this can also be other distances, and such as 6mil or 8mil etc. no longer go to live in the household of one's in-laws on getting married herein
State.
The transmission of communication device 120 is to pass through the ground Network Isolation with the second default spacing between differential signal, adjacent signals,
Such that it is able to ensure continual and steady and zero error transmissions of communication signal, while the antijamming capability of signal itself is strengthened,
The radiation signal that itself is produced is preferably minimized, and has good protective effect to device itself and adjacent devices.
(PCC) power 130 can include at least one power part, and paving copper is repeated in the lower section multilayer of at least one power part,
Power part is, for example, MOS（Metal-oxide-semiconductor field effect transistor, metal-oxid-semiconductor).It is excellent
Selection of land, paving copper is repeated in the lower section multilayer of all power parts of (PCC) power 130, and the number of plies for spreading copper can be according to specific boards
The number of plies and power be configured.For example：When circuit board is 6 layers, the number of plies that can repeat paving copper is 4 layers, wherein, bottom does not spread
If copper.
In the examples described above, (PCC) power 130 is operationally by high current, produces temperature higher, thus by
The paving copper that the fin of (PCC) power 130 lower section multilayer is repeated, increases heat-dissipating space and heat dissipation channel, accelerates radiating rate, as early as possible
Dissipate heat, the temperature-sensitive device to itself and periphery forms good protection, it is ensured that the work of component safety and stability.Enter one
Step ground, printed circuit board (PCB) provided in an embodiment of the present invention can also radiate to (PCC) power 130 in the following manner, for example
Increase by least one power part output pin wire widths of (PCC) power 130, lower section multilayer is used at least one power part
Wiring, so as to increased heat-dissipating space and heat dissipation channel, improves radiating rate, it is ensured that the work of the safety and stability of (PCC) power 130.
Additionally, on the basis of the above-mentioned radiating treatment to (PCC) power 130, it is special that power part can also increased
Radiating treatment, including at least one power part 130 is close to the heat-conducting pad of printed circuit board (PCB) 100.Specifically, heat-conducting pad is filled out
The gap filled between power part and the shell fin of printed circuit board (PCB) 100, for accelerating the radiating to power part, improves work(
The service life of rate part.Wherein, heat-conducting pad can be insulating heat-conductive pad.
The back side windowing dew copper sheet of power part, the copper sheet that will be exposed are close to printed circuit board (PCB) by insulating heat-conductive pad
100 shell fin, so as to greatly improve radiating rate, it is ensured that the work of the power part safety and stability.Thus, fill
Divide using the heat dissipation design of mechanical cover, make power part（That is heating element）It is close to the fin of shell, by enclosure interior
Heat leads rapidly hull outside, so as to strengthen the service life of component.
Printed circuit board (PCB) according to embodiments of the present invention, ground network shielding protection is carried out to the sensitive signal on circuit board,
Strengthen the antijamming capability of signal itself and reduce the radiation interference of device to external world, enough radiatings are given to heater element empty
Between i.e. heat dissipation channel, so as to form good protection to heat sensitive component, strengthen the service life of component.
It is electric to printing provided in an embodiment of the present invention so that (PCC) power 130 includes two power parts as an example with reference to Fig. 2
The structure of road plate is described in detail.
As shown in Fig. 2 printed circuit board (PCB) 100 according to embodiments of the present invention includes：Input/output interface 110, communicator
Part 120 and (PCC) power 130, wherein, (PCC) power 130 includes the first power part 131 and the second power part 132.
Specifically, by the ground Network Isolation between the adjacent sensitive signal of input/output interface 110 with 10mil spacing, it is to avoid
Signal is shown in generation crosstalk, causes signal transmission mistake occur.Communication device 120 is differential signal, 7mil will be used between adjacent signals
The ground Network Isolation of spacing, so that it is guaranteed that continual and steady and zero error transmissions of signal.Specifically, land used networking shielding letter
Number, not only increase the antijamming capability of signal itself, the radiation signal for also producing itself is preferably minimized, to device itself and
Its adjacent devices is thought of as good protection.First power part 131 and the second power part 132 are heat sensitive component, have during work
High current is passed through, and produces higher temperature, therefore multilayer can repeat paving copper, increase above-mentioned two power part below its fin
Output pin wire widths and by the way of multilayer wiring, so give enough heat-dissipating spaces and heat dissipation channel, it is ensured that
Can radiate in time, it is to avoid the damage of component.Further, special dissipating can also be also add to the second power part 132
Heat treatment, by component back side windowing dew copper sheet, and is close to printed circuit board (PCB) 100 by copper sheet is exposed by insulating heat-conductive pad
Fin, so as to greatly improve radiating rate, it is ensured that the work of component safety and stability.Print according to embodiments of the present invention
Printed circuit board, ground network shielding protection is carried out to the sensitive signal on circuit board, is strengthened the antijamming capability of signal itself and is dropped
The radiation interference of low device to external world, enough heat-dissipating spaces and heat dissipation channel are given to heating element, so as to thermal element
Device forms good protection, strengthens the service life of component.Additionally, using printed circuit provided in an embodiment of the present invention
Plate is made the entire car controller of electric automobile, it is ensured that the safe and reliable grade of entire car controller
Further embodiment of the present invention also proposed a kind of electric automobile, including first aspect present invention embodiment is proposed
