[0032] In related art, in order to analyze the signals between the motherboard and the daughter card, an adapter card is designed. Installed between the motherboard and the daughter card, the adapter card is connected to the external device and communicates with it through an external cable. However, this adapter card has the following defects:
[0033] 1. The adapter card requires multiple connectors and multiple signal lines to connect to the daughter card with other connectors, and then connect to the external device, or directly connect to the external device, which is more troublesome in assembly and may cause connection errors.
[0034] 2. The adapter card consists of multiple daughter cards, which increases the production cost and process difficulty.
[0035] 3. There are multiple daughter cards on the motherboard, and the space between the daughter cards is very limited. It is necessary to consider whether the space can accommodate multiple signal lines.
[0036] 4. Too many signal lines will affect the motherboard's heat dissipation and other performance.
[0037] 5. The unit price of connectors and signal lines is relatively expensive, so the total production cost is relatively high.
[0038] Based on this, the utility model provides an adapter card for testing, which adopts a soft-hard combination board structure to replace the connector and signal line, so that the adapter board and the sub-boards are connected through the soft board, and the adapter boards are combined into an integral adapter card.
[0039] See also Figure 1 , Figure 1 This is one of the schematic diagrams of the top view structure of the adapter card provided by the utility model.
[0040] In this embodiment, the adapter card 100 may include an intermediate rigid board 110 , at least one interface rigid board 120 and a flexible board 130 ; the intermediate rigid board 110 is connected to the main board and the daughter card respectively, and is connected to each interface rigid board 120 respectively through the flexible board 130 .
[0041] Each interface rigid board 120 is provided with a signal interface for connecting to an external signal analyzer. The middle rigid board 110 is provided with at least one signal analysis module for analyzing signals between the external signal analyzer, the mainboard and / or the daughter card.
[0042] Both the intermediate rigid board and the interface rigid board are circuit boards made of a rigid material (such as epoxy resin) and can be composed of multiple layers of laminate, each layer containing conductive circuits and insulating layers. The layers are connected by holes and through-holes to form a complete circuit. The rigid board has high strength and stability and can support complex circuit designs. In this embodiment, the intermediate rigid board and the interface rigid board each have different functional modules. For example, the intermediate rigid board is provided with a signal analysis module, and the interface rigid board is provided with a signal interface.
[0043] A flexible circuit board is made of a flexible material (such as polyimide) that can be bent, folded, and rolled. Because it's thin and lightweight and can be rolled, it's highly flexible and can adapt to complex spatial layouts. In this example, it primarily serves as a signal line.
[0044] The motherboard and daughter card are two components in computer hardware. The motherboard, also known as the motherboard or system board, provides the connections between the various parts inside the computer and allows them to communicate with each other.
[0045] A daughter card, also known as an expansion card or interface card, is a hardware device that plugs into an expansion slot on a motherboard. The main purpose of an expansion card is to add additional functionality or interfaces to the motherboard, thereby expanding the capabilities of the computer.
[0046] Optionally, the types of expansion cards may include graphics cards, sound cards, network cards, storage expansion cards, and interface expansion cards.
[0047] The signal analysis module is used to analyze the signals between the peripheral signal analyzer, the mainboard and / or the daughter card, and can output the results of the hardware test. Optionally, the signal analysis module is a protocol analyzer that can capture, decode and analyze data packets in the interface communication.
[0048] Optionally, the signal analysis module can be integrated with the intermediate rigid board to further simplify the connection operation; the intermediate rigid board can also be designed as a module independent of the intermediate rigid board, that is, as an external device of the intermediate rigid board, it needs to be additionally connected before use. However, the advantage of the independent module design is that the signal analysis module can be replaced.
[0049] In this embodiment, an external signal analyzer is also provided, and each interface rigid board is provided with a signal interface for connecting to the external signal analyzer. Optionally, the signal interface may include a gold finger and a SLOT interface.
[0050] Through the above approach, this embodiment uses a rigid-flex board structure to replace connectors and signal lines. The adapter card as a whole can be used for signal analysis of the motherboard and / or daughter card. The adapter card of this embodiment has the following advantages:
[0051] 1. The assembly operation is simple. You only need to connect the adapter card and the signal analysis module without worrying about incorrect connection.
[0052] 2. The adapter card as a whole has a lower manufacturing process difficulty.
[0053] 3. The thickness of the flexible board is thin, and the limited space between expansion cards can be met.
[0054] 4. It is relatively neat after assembly and will not affect the heat dissipation performance of the motherboard.
[0055] 5. The production cost is low, equivalent to the price of a connector.
[0056] 6. Flexible boards take up less space, are more flexible, and can be combined in a variety of ways.

Furthermore, a gold finger is provided on the first rigid board 121 as a first interface, and a slot interface is provided on the second rigid board 122 as a second interface.
[0069] In some embodiments, the first signal includes one of a PCIE signal, a P2P signal, a single-ended signal, a CLK signal, and a power signal.
[0070] Among them, PCIE signal is the signal obtained through the PCIe bus transmission on the motherboard; P2P signal refers to the signal obtained through point-to-point communication transmission; single-ended signal refers to the signal obtained by using only one signal line and a common reference ground line (usually ground) for transmission. Generally, only some single-ended signals that require attention are obtained; CLK signal refers to the clock signal on the motherboard; power signal refers to the signal or voltage that provides power on the motherboard.
[0071] Generally, one communication interface can only obtain one signal. Therefore, when multiple signals need to be analyzed and processed simultaneously, multiple interfaces need to be provided on the adapter card.
