[0023] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the specific protection scope requested by the utility model.

[0024] As Figures 1-3 shown, a double-path high-performance PCB, comprising a first chip positioning clamp 2 and a second chip positioning clamp 5 clamped to each other by a bolt nut assembly 4, a first chip seat 6 and a second chip seat 7 oppositely arranged in the middle of the first chip positioning clamp 2 and the second chip positioning clamp 5, and a chip 3 provided on one side of the top of the second chip seat 7.

[0025] And a circuit board 1, the middle of the circuit board 1 is provided with a mounting hole 11, and the first chip seat 6 and the second chip seat 7 are oppositely clamped inside the mounting hole 11.

[0026] Further, the top of the second chip seat 7 surrounds the top of the side edge of the chip 3 and is provided with a pressing plate 21, and the pressing plate 21 abuts against the inner side of the first chip positioning clamp 2, so that the pressing plate 21, the side edge of the chip 3 and the top surface of the second chip seat 7 are tightly attached.

[0027] According to the above structure, the installation method is as follows:

[0028] First, the first chip seat 6 and the second chip seat 7 are respectively installed on both sides of the mounting hole 11 inside the circuit board 1, so that the first chip seat 6 and the second chip seat 7 are closely attached, and the electrical connection path between the first chip seat 6 and the circuit board 1, the first chip seat 6 and the second chip seat 7, and the second chip seat 7 and the circuit board 1 is tested to determine whether the electrical path is normal and whether there is a broken circuit condition. Then, the second chip positioning clamp 5 is aligned at the bottom of the first chip seat 6, and the pressing plate 21 is installed according to the type of chip 3. If the chip 3 is a chip with pins on the side or a micro control chip, etc., as shown in the figure, the pins on the side need to be reinforced, connected and positioned. Therefore, the pressing plate 21 and the first chip positioning clamp 2 can be used to achieve extrusion and fixation. When the chip is a graphics chip or a central processing unit chip, the pins are located at the bottom of the chip, and need to be connected with the corresponding pins at the top of the second chip seat 7. The protrusions provided inside the first chip positioning clamp 2 directly press against the top of the chip 3, making the pin connection more stable. After the chip 3 is installed, the bolt and nut assembly 4 penetrates the first chip positioning clamp 2 and the circuit board 1, and the bolt and nut assembly 4 located between the first chip positioning clamp 2 and the circuit board 1 is also sleeved with a column. The bolt and nut assembly 4 and the column are installed, and the installation is completed. The column therein includes a plastic column for controlling the compression degree or an elastic column to improve the adjustability of the chip compression process.

[0029] The principle is:

[0030] The first chip positioning clamp 2 and the second chip positioning clamp 5 are clamped and installed on the chip 3 through the bolt and nut assembly 4, so that the chip 3 can be replaced. When the chip needs to be replaced, such as an iterative chip product, only the second chip seat 7 of the corresponding path needs to be replaced, so that the pins of the corresponding functional partition can realize the corresponding function. For other upgraded products with new functions, the corresponding circuit board 1 can be replaced. In particular, in terms of function matching test between the chip 3 and the circuit board 1, the test is more convenient. In addition, during use and installation, the chip connected by the bridge can also be replaced adaptively. For example, the bridge protocol of the corresponding functional area of the notebook mainboard can be realized by replacing the chip, so that the performance of the notebook can be effectively improved at a lower cost. This method can also be used in fields such as computer mainboards and controller mainboards. In addition, for those skilled in the art, the replacement of the chip needs to be adaptively tested for its power supply power. During the test, the size of the chip and the power supply power needs to be adjusted. The method includes replacing the power supply power controller, etc. The above is a technical problem that can be solved by those skilled in the art, so it is not necessary to repeat it here.

[0031] Based on the above, and with reference to Figures 2-5The top surface of the second chip seat 7 is provided with a groove for mounting the chip 3, and the groove is internally provided with electrically connected contacts adapted to the chip 3, and the contacts are respectively electrically connected with the first chip seat 6 and the circuit board 1 through the contacts on the side surface and the bottom of the second chip seat 7.

[0032] The structure of the opposite surface of the second chip seat 7 and the first chip seat 6 is different, and the internal passage path depends on the use of different chips 3.

[0033] Specifically, the chip 3 is connected through extrusion between the chip 3 and the second chip seat 7 or through tin soldering connection, the inside of the first chip positioning clamp 2 abuts against the top of the chip 3, the chip 3 mainly transmits electric signals to the second chip seat 7, the second chip seat 7 is made into a circuit adapted to different functional partitions on the circuit board 1 according to the different passage of the chip 3, and the first chip seat 6 realizes the bridging effect to connect different functional partitions to the circuit on the other surface of the circuit board 1, thereby realizing the integrated connection of the double-way PCB board function.

[0034] For reference Figure 4 and Figure 5 When the mounting hole 11 is externally provided with two side surfaces, the two side surfaces are respectively adapted to and attached to the first chip seat 6 and the second chip seat 7, at this time, the side edges of the first chip seat 6 and the second chip seat 7 are also side edges adapted to the two side surfaces, at this time, the side edges can save the thickness of the double-way PCB board when the chip 3 needs to be connected to fewer contacts, and through the arrangement of the two side surfaces, high-power chips 3 and accessories can be used, when the circuit board 1 has high precision and high line density, the mounting hole 11 with no less than two side surfaces can be used to connect more contacts and circuits, and the setting of the layer circuit is realized.

[0035] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the present application, some improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection range of the present application. The structures, devices and operation methods not specifically described and explained in the present application are implemented according to the conventional means in the art without special description and limitation.
