Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
Fig. 1 is a schematic top view of a high-speed signal motherboard according to an embodiment of the present disclosure. As shown in fig. 1, the high-speed signal motherboard includes a motherboard body 10 and a plurality of embedded printed circuit boards 11, at least a part of the embedded printed circuit boards 11 are connected and fixed to a communication terminal area of the motherboard body 10; the embedded printed circuit board 11 includes a high-speed board substrate and a plurality of electronic devices disposed on the high-speed board substrate.
Specifically, the main board body 10 may be configured as a low-speed board substrate, that is, the main board body 10 is configured as a normal board, the embedded printed circuit board 11 is disposed on a partial area of the main board body 10, for example, a communication end area, and the area where the embedded printed circuit board 11 is located is the communication end area shown in fig. 1. The embedded printed circuit board 11 is provided as a high-speed board substrate, and a plurality of electronic devices, which are electronic devices required for communication, such as electronic devices that receive high-speed signals, are provided on the high-speed board substrate.
Among them, the high-speed board has characteristics of low Dielectric constant (Dk), low Dielectric loss factor (Df), and low Roughness (Roughness). The dielectric constant, also called dielectric constant or dielectric coefficient, is a coefficient used to characterize the insulation of a material and is designated by the letter epsilon. In engineering applications, the dielectric constant is often expressed in terms of relative dielectric constant, rather than absolute value, and is often used in calculating impedance and time delay. The dielectric loss factor, also called damping factor, internal loss (internal dissipation) or loss tangent (loss tangent), is the tangent of the phase difference angle between strain and stress cycle of a material under the action of an alternating force field, and is also equal to the ratio of the loss modulus to the storage modulus of the material (i.e. the ratio of the energy lost in the insulating board in a signal line to the energy still existing in the line). In the transmission process of high-speed signals, the loss of the high-speed signals is closely related to the dielectric constant, the dielectric loss factor and the roughness of materials. For example, the lower the dielectric constant, dielectric dissipation factor, and roughness of a material, the less the loss of a high speed signal. Therefore, the embedded printed circuit board 11 is set as a high-speed board substrate, which is beneficial to reducing the loss of high-speed signals.
Among them, electronic devices receiving high-speed signals are generally disposed in the communication end region, and such electronic devices belong to a three-dimensional structure, and inserting such electronic devices of a three-dimensional structure into the main board body 10 disposed as a low-speed board substrate is one of the main causes of the high-speed signal loss becoming large. Therefore, in the embodiment of the present application, such electronic devices are disposed in the embedded pcb 11 of the high-speed board substrate, and the embedded pcb 11 is disposed at the communication terminal area, that is, a part of the embedded pcb 11 is connected and fixed to the communication terminal area of the motherboard main body 10, so that when the electronic device receives a high-speed signal, the high-speed board substrate of the embedded pcb 11 is utilized to avoid a large high-speed signal loss caused by the fact that the electronic device is directly inserted into the motherboard main body 10 of the low-speed board substrate, thereby being beneficial to reducing the loss of the high-speed signal.
Thus, providing the embedded printed circuit board 11 including a high-speed board substrate at the communication end region avoids providing the main board main body 10 as a circuit board including a high-speed board substrate while achieving reduction in high-speed signal loss, thereby contributing to cost reduction.
Exemplarily, at a frequency of 10GHz, printed circuit boards of different board substrates are disposed and embedded in the communication terminal area of the main board body 10, respectively, and a simulation test is performed on loss of a high-speed signal, and table 1 shows a result of the simulation test. As shown in table 1, N represents different types of board substrates, eight different types of board substrates are shown in table 1, DK represents the dielectric constant of the board, DF represents the dielectric loss factor of the board, roughnesss represents the Roughness of the board in microns, and insertional loss represents the loss of the high speed signal in decibels. As can be seen from table 1, the lower the dielectric constant, dielectric dissipation factor and roughness of the printed circuit board material embedded in the main board body 10, the lower the loss of the high-speed signal. From the simulation test results shown in table 1, it can be obtained that the eighth material has the lowest loss for high-speed signals, and thus the eighth material can be used as the board substrate of the embedded printed circuit board 11 in the embodiment of the present application, that is, the embedded printed circuit board 11 is set as the high-speed board substrate.
As shown in table 1, eight kinds of printed circuit boards with different board substrates were respectively embedded in the communication terminal area of the main board body 10 at a frequency of 10GHz, and a simulation test was performed on loss of a high-speed signal. It can be obtained through simulation test results that when the eighth material is used as the board substrate of the printed circuit board, the loss of the high-speed signal is 2.4688dB, and when the first material is used as the board substrate of the printed circuit board, the loss of the high-speed signal is 3.6995dB, so that it can be obtained through comparison results that when the high-speed board substrate, that is, the eighth material is embedded in the printed circuit board of the board substrate, the total loss of the high-speed signal can be reduced by 1.8dB.
It should be noted that, at a frequency of 10GHz, the simulation test results shown in table 1 only exemplarily show that a signal transmission line of 2inch is provided in the embedded printed circuit board 11. For high-speed signal transmission lines generally as long as 10-40 inch, when the eighth material is used as a plate substrate, namely, a high-speed plate substrate is used for simulation test, the high-speed signal transmission line has more remarkable effect of reducing the loss of high-speed signals.

As shown in table 2, eight kinds of printed circuit boards with different board substrates were respectively embedded in the communication terminal area in the main board body 10 at a frequency of 20GHz, and a simulation test was performed on loss of a high-speed signal. It can be obtained through simulation test results that when the eighth material is used as the board substrate of the printed circuit board, the loss of the high-speed signal is 2.7858dB, and when the first material is used as the board substrate of the printed circuit board, the loss of the high-speed signal is 6.3904dB, so that it can be obtained through comparison results that the total loss of the high-speed signal can be reduced by 3.6dB by using the high-speed board substrate, that is, the eighth material, as the board substrate.
It should be noted that, at a frequency of 20GHz, the simulation test results shown in table 2 only exemplarily show that a signal transmission line of 2 inches is provided in the embedded printed circuit board 11. For high-speed signal transmission lines generally as long as 10-40 inch, when the eighth material is used as a plate substrate, namely, a high-speed plate substrate is used for simulation test, the high-speed signal transmission line has more remarkable effect of reducing the loss of high-speed signals.
Thus, it can be obtained from the simulation test results of tables 1 and 2 that when the embedded printed circuit board 11 of the high-speed board substrate is disposed at the communication terminal area of the main board body 10, it is advantageous to reduce the loss of high-speed signals; in particular, as the frequency is higher, the effect on reducing the high-speed signal loss is more remarkable. Illustratively, the High-speed signal may include a Double Data Rate (DDR) signal, a High Definition Multimedia Interface (HDMI) signal, a Thunderbolt Interface (TBT) signal, a High speed Serial computer extended Bus (PCIE) signal, a Universal Serial Bus (USB) signal, a display Interface (DP) signal, and a Mobile Industry Processor Interface (MIPI) signal.
The high-speed signal main board provided by the embodiment of the application comprises a main board main body and a plurality of embedded printed circuit boards, wherein at least part of the embedded printed circuit boards are connected and fixed to a communication terminal area of the main board main body; the embedded printed circuit board includes a high-speed board substrate and a plurality of electronic devices disposed on the high-speed board substrate. Therefore, the embedded printed circuit board of the high-speed board substrate is arranged at the communication terminal area of the main board body, and meanwhile, the electronic device for receiving the high-speed signal is arranged on the high-speed board substrate, namely, a plurality of electronic devices are arranged on the same embedded printed circuit board. In addition, the circuit board with the whole main board body set as the high-speed board substrate is avoided while the high-speed signal loss is reduced, so that the cost is reduced.
In an embodiment, fig. 2 is a schematic top view of another high-speed signal motherboard according to an embodiment of the present application. Referring to fig. 2, at least a portion of the embedded printed circuit board 11 is fixedly connected to the first region of the main board body 10; the first area is a middle preset area of the main board body.
Specifically, a simulation test is performed on the non-communication terminal area of the main board body 10, and the specific position of the first area on the main board body 10 can be determined according to the simulation test result. Exemplarily, a preset loss threshold is set, and according to a simulation test result, when it is determined that the loss of a certain region on the main board body 10 for a high-speed signal is greater than the preset loss threshold, it may be determined that the loss of the middle region of the main board body 10 for the high-speed signal is greater, and then the region is used as a first region, that is, the middle preset region, and further, the embedded printed circuit board 11 is disposed in the first region, which is beneficial to reducing the loss of the high-speed signal, thereby ensuring the integrity of the high-speed signal.
In one embodiment, with reference to fig. 2, a central processing unit 12 is fixedly connected to the main board body 10, and the central processing unit 12 is electrically connected to a predetermined first embedded pcb through traces 13 in the main board body 10; the middle preset area is an area with the loss on the wiring larger than the preset loss; the first embedded pcb is an embedded pcb 11 disposed corresponding to the communication end region.
Specifically, a first embedded printed circuit board is disposed on the main board body 10 corresponding to the communication terminal area, and the first embedded printed circuit board is electrically connected to the central processing unit 12 disposed on the main board body 10, so that the central processing unit 12 controls the transmission of high-speed signals in the first embedded printed circuit board. When a high-speed signal is transmitted from the first embedded pcb to the cpu 12 along the high-speed transmission line, i.e. the trace 13, if a certain area on the main board 10 has a large loss to the high-speed signal, for example, the loss is greater than a predetermined loss, the current area can be used as a middle predetermined area, and the embedded pcb 11 is disposed in the middle predetermined area, so that the high-speed board substrate of the embedded pcb 11 is used to reduce the loss of the high-speed signal, thereby achieving the integrity of the high-speed signal.

The preferred implementation of the embodiment of the present application is to stack all the electronic devices 14 in a direction perpendicular to the embedded printed circuit board 11, which is beneficial to shorten the signal transmission line for connecting the electronic devices 14.
In one embodiment, with continued reference to fig. 3 or 4, the stacked electronic devices 13 are electrically interconnected by through-silicon vias.
Among other things, the stacking technique may also be called a 3D stacking technique, and the stacking technique is used to realize three-dimensional integration of a plurality of electronic devices 14 in the Z-axis direction through interconnection or other micromachining techniques. In addition, the three-dimensional electronic device allows multi-layer stacking, and improves the integration of the electronic device 14 by implementing communication of a plurality of electronic devices 13 in a vertical direction through the through-silicon vias.
Specifically, silicon is a dielectric layer in the electronic device 14, the dielectric layer in the electronic device 14 is perforated, and the upper and lower electronic devices 14 can be electrically connected through vertical traces in the silicon through holes, that is, the stacked electronic devices 14 are electrically connected through the silicon through holes. Therefore, the electronic devices 14 can be stacked to be in close contact with each other in the vertical direction, and compared with the case where the electronic devices 14 are laid on the embedded printed circuit board 11, the signal transmission line for connecting the electronic devices can be shortened.
