140XBP00300 | 机架背板 | 实现主控板与业务板间的高速数据互连
零件编号 编号：140XBP00300
安装支持 架
产品或组件类型 ：机架背板
产品特定应用 ：对于本地 I/O 模块
安装支持 ：安装板
定义：
140XBP00300 机架背板是支撑其他电路板、器件和器件之间相互连接的电路板或框架。
它不仅提供了所支撑器件的电源和数据信号，还是PCB制造业中具有专业化性质的产品。
特点：
背板较常规PCB板要厚和重，以适应大功耗应用卡的需求。
铜层厚度适中，以确保提供所需电流，保证卡能正常工作。
功能：
140XBP00300 实现主控板与业务板间的高速数据互连及系统各类管理及控制信号的交换。
支持单板的带电插拔，自动识别各槽位和机架类型。
与电源模块相连，实现系统分布式供电。
引入风扇框和电源的监控信号线。
通信链路：
140XBP00300 背板上的通信链路包括控制链路和数据链路，分别传递控制信息和数据信息。
在正常转发时，要交换的数据不会在两个主控板间传递，只会在主控板和业务板以及各业务板间交互。
种类：
除了在电子和通信领域使用的背板外，还有钢制背板、木制背板等其他种类的背板。
钢制背板主要用于机械设备和建筑工程中，提供结构强度和稳定性，并可以减轻机器的重量。
木制背板则用于家具制造和建筑材料生产中，具有美观和装饰作用。
Part Number: 140XBP00300
Mounting support bracket
Product or component type: Rack backplane
Product specific application: For local I/O modules
Installation support: Mounting board
Definition:
140XBP00300 A rack backplane is a circuit board or frame that supports the interconnections between other circuit boards, devices, and devices.
It not only provides the power and data signals of the supported devices, but also has a professional nature of the PCB manufacturing industry.
Features:
The backplane is thicker and heavier than the conventional PCB board to meet the needs of high-power application cards.
The thickness of the copper layer is moderate to ensure that the required current is provided to ensure the normal operation of the card.
Features:
140XBP00300 Realizes high-speed data interconnection between the main control board and the business board and the exchange of various management and control signals of the system.
Supports onboard insertion and removal of boards, and automatically identifies slots and rack types.
Connect to the power module to realize distributed power supply.
The monitoring signal cables for the fan frame and power supply are introduced.
Communication links:
140XBP00300 Communication links on the backplane include control links and data links, which transmit control information and data information respectively.
In normal forwarding, the data to be exchanged is not transmitted between the two MPUs, but only between the MPUS and the SPUs, and between the SPUs.
Type:
In addition to backplanes used in the field of electronics and communications, there are other types of backplanes such as steel backplanes and wooden backplanes.
The steel backplane is mainly used in mechanical equipment and construction projects to provide structural strength and stability, and can reduce the weight of the machine.
Wooden backboards are used in furniture manufacturing and building material production, with aesthetic and decorative effects.
