[0079] Optionally, as an example, the first signal layer can be the outermost copper foil of the adapter board, with serial communication, fan control, and other signal traces etched on its surface, serving as a soldering carrier for components and gold finger contacts; the first ground layer can be a full-plane copper foil adjacent to the first signal layer, with a grounding network laid across the entire board to provide a low-impedance reference plane for signal return and reduce external electromagnetic radiation; the first power layer can be a full-plane copper foil adjacent to the first ground layer, used to carry the 12V main power supply and form a parallel plate capacitor with the ground layer to reduce the power impedance in the high-frequency band; the second power layer can be another full-plane copper foil parallel to the first power layer, with the two power layers connected in parallel to expand the copper cross-sectional area and meet the temperature rise limit of 120 A continuous current; the second ground layer can include, but is not limited to, a full-plane copper foil adjacent to the second signal layer, with its potential connected at the same potential as the first ground layer, forming a dual return plane to further reduce common-mode noise; the second signal layer can be the outermost copper foil on the other side of the adapter board, used to lay out the remaining signal network and tightly coupled with the second ground layer to maintain impedance continuity.
[0080] Alternatively, the specific details of the above six layers can be found in Table 1:
[0081] Table 1
[0082]
[0083] In this design, the top layer 1 represents the first signal layer, the ground layer 2 represents the first ground layer, the power layer 3 represents the first power layer, the power layer 4 represents the second power layer, the ground layer 5 represents the second ground layer, and the bottom layer 6 represents the second signal layer. Optionally, in the 6-layer board design, the stack-up thickness can be, but is not limited to, 61.44 mil (1.56 mm). The ground layer and power layer can be, but are not limited to, a symmetrical 2 oz copper thickness design to ensure that the current of the power supply unit (PSU) can reach more than 120A. The signal lines are mainly routed on the top layer 1 and the bottom layer 6 to ensure that the signal reference is a complete ground layer and that the signal traces are not interfered with by high-frequency signals and power signals.
[0084] By employing the embodiments of this utility model, the physical separation of signal lines and power lines is achieved through the layered arrangement of control signal lines, current transmission lines and grounding lines. This effectively suppresses signal interference, ensures unobstructed current transmission, enhances the reliability and coverage of the grounding network, and improves the overall electrical performance of the circuit board.
[0085] As an optional embodiment, the line width of the first type of control line used for transmitting control signals in the adapter board is a first width, and the first type of control line is used to transmit control signals that match the target communication protocol;
[0086] The second type of control circuit in the adapter board, used for transmitting control signals, has a line width of the second width. The second type of control circuit includes fan speed control signal circuit, fan speed measurement signal circuit, fan enable signal circuit, power supply unit voltage detection signal circuit, and power supply unit voltage current sharing signal circuit.
[0087] The second width is smaller than the first width.
[0088] Optionally, the aforementioned first type of control lines may, but are not limited to, be used to represent lines that transmit conventional control signals. These signals may include, but are not limited to, Inter-Integrated Circuit (I2C) signals, and their line width is defined as the first width. The width setting of I2C and other signal lines (e.g., 11.9 mil) ensures the control of the signal line impedance, for example, keeping it at around 50 ohms. This is crucial for signal integrity, ensuring that the signal does not reflect during transmission on the line and maintaining the purity of the signal waveform.
[0089] It should be noted that the aforementioned second type of control lines may include, but are not limited to, lines that transmit specific function control signals, such as fan speed control signal lines (FAN_PWM), fan speed measurement signal lines (FAN_TACH0 / FAN_TACH1), fan enable signal lines (FAN_LED_PWREN), power supply unit voltage detection signal lines (PSU_SENSE_P), and power supply unit voltage current sharing signal lines (PSU_SHARE). The width of these lines is defined as the second width. Since the second width is smaller than the first width, this design takes into account maintaining signal stability and reducing signal attenuation under high-speed and high-load conditions.
[0090] Furthermore, the aforementioned first width may, but is not limited to, refer to the width of the lines on the adapter board used to transmit basic control signals. This width, for example, 11.9 mil, is chosen to ensure that the signal lines have the correct characteristic impedance, thereby preventing excessive signal reflection or transmission loss on the signal lines and maintaining signal integrity and efficiency.
[0091] Optionally, the second width mentioned above may, but is not limited to, the line width on the adapter board used for transmitting critical or high-frequency control signals, and may be smaller than the first width, such as 10 mil. This design ensures signal integrity and immunity under high bandwidth and high load conditions. Especially for signal types that require higher current or higher frequency transmission, wider lines help improve signal quality and reduce crosstalk between lines.
[0092] It should be noted that the control signals that match the target communication protocol mentioned above may include, but are not limited to, those designed according to a specific communication protocol standard, such as I2C.
[0093] By employing the embodiments of this utility model, high-precision transmission of critical signal lines is achieved through differentiated configuration of line widths for different types of control signal lines, as well as additional protection for sensitive signals such as voltage detection and current sharing signals. This reduces signal distortion and improves the reliability of signal transmission and the accuracy of data.
[0094] As an optional embodiment, the spacing between the first type of control line and the adjacent line is a first spacing;
[0095] The spacing between the fan speed control signal line and the adjacent line is the first spacing.
[0096] The spacing between the power supply unit voltage detection signal line and the power supply unit voltage current sharing signal line and the adjacent lines is the second spacing.
[0097] Except for the first type of control line, fan speed control signal line, power supply unit voltage detection signal line and power supply unit voltage current sharing signal line, the distance between the line and the adjacent line is greater than the predetermined distance.
[0098] Among them, the first spacing is smaller than the second spacing, and the predetermined spacing is smaller than the first spacing.
[0099] It should be noted that the aforementioned first spacing may include, but is not limited to, a carefully adjusted distance value to ensure a reasonable interval between the first type of control lines and adjacent lines. The selection of the first spacing must consider both signal stability and efficient use of the adapter board space, and is generally set to be smaller than the second spacing to accommodate the high-density wiring requirements of signals such as I2C. For example, the first spacing may be, but is not limited to, set to 20 mil.
[0100] Furthermore, the aforementioned second spacing may, but is not limited to, a distance larger than the first spacing, to ensure sufficient isolation between sensitive lines such as the power supply unit voltage detection signal line and the voltage current sharing signal line and surrounding lines, preventing the impact of high-frequency noise or power fluctuations on signal quality, thereby achieving higher signal transmission accuracy and system stability. For example, the second spacing may, but is not limited to, be set to 25 mil.
[0101] Optionally, the aforementioned predetermined spacing may, but is not limited to, represent a basic spacing distance set for general signal lines in the adapter board design. This spacing is smaller than the first spacing, meaning that the minimum clearance between most signal lines, except for those specifically mentioned, is set more leniently. This helps to maximize space utilization while ensuring basic signal quality. For example, the predetermined spacing may, but is not limited to, be set to 19.68 mil to meet the condition of ≥3W (18.06 mil), which can effectively prevent crosstalk and interference between signals and ensure effective and distortion-free signal transmission.
[0102] By employing the embodiments of this utility model, the differential configuration of the spacing between different lines achieves precise control of signal interference, especially prioritizing the protection of sensitive voltage detection signals and current sharing signals, while optimizing the space utilization of the circuit board.
[0103] As an optional embodiment, the spacing between the welding area and the gold finger area is smaller than the target spacing.
[0104] It should be noted that the target spacing mentioned above may include, but is not limited to, the maximum allowable distance threshold set during the design phase. Layouts smaller than this threshold are considered to meet the compactness requirements. For example, assuming the predetermined spacing is 1.1mm, the aforementioned "spacing" may be set to, but is not limited to, 1mm.
[0105] Optionally, the aforementioned "less than target spacing" may, but is not limited to, indicate that the actual measured distance between the edges of the two regions falls below the threshold range, thereby shortening the conductive path, reducing the loop impedance, and saving material.
[0106] Optionally, as an example, after configuring the signal trace width and spacing, the PCB traces are routed according to the pin definitions. Signal lines run on three layers: top layer 1, bottom layer 6, and power layer 4. The two nets on power layer 4 have complete ground plane signals referenced on both sides. Power lines run on four layers: top layer 1, bottom layer 6, power layer 3, and power layer 4, with a power copper shape width of at least 2400 mil to ensure the Power Supply Unit 12V (PSU_12V) power supply meets at least 120A. Ground plane lines are laid with a ground shape across all layers of ground layer 2 and ground layer 5. Ground connection points and empty areas on other layers are also laid with ground plane shapes. This design not only reduces layer stack-up but also ensures signal quality and power signal output efficiency across the entire board. Power signal output efficiency can reach 100%, enabling lossless transmission.
[0107] By employing the embodiments of this utility model, the ultra-small target spacing design between the soldering area and the gold finger area achieves extremely high circuit board space efficiency and the possibility of realizing complex signal and power connections in a small space, saving circuit board area and facilitating deployment and maintenance in high-density server environments.
[0108] As an optional embodiment, the gold finger area includes a first gold finger area and a second gold finger area located on both sides of the adapter board. The first gold finger area includes at least one second power via pin, at least one second control signal via pin, and at least one second ground pin. The second gold finger area includes at least one second power via pin, at least one second control signal via pin, and at least one second ground pin.
[0109] It should be noted that the first and second gold finger areas mentioned above may include, but are not limited to, gold finger areas independently set on both sides of the adapter board. They each contain a series of pins for electrical connection with the server's power connector and power supply module, ensuring bidirectional transmission of power and control signals.
[0110] By adopting the embodiments of this utility model, the dual-sided design of the first gold finger area and the second gold finger area enhances the mechanical strength and electrical connection stability of the circuit board. By distributing the layout of power supply and signal pins, the current path and signal transmission are optimized, while providing a more balanced power distribution and control signal routing for large servers.
