Description: （一） 布局设计原则
1． 距板边距离应大于5mm。
2． 先放置与结构关系密切的元件，如接插件、开关、电源插座等。
3． 优先摆放电路功能块的核心元件及体积较大的元器件，再以核心元件为
中心摆放周围电路元器件。
4． 功率大的元件摆放在利于散热的位置上，如采用风扇散热，放在空气的
主流通道上；若采用传导散热，应放在靠近机箱导槽的位置。
5． 质量较大的元器件应避免放在板的中心，应靠近板在机箱中的固定边放
置。-(A) the layout of Principle 1. Distance from the plate edge should be larger than 5mm. 2. First place and structure of closely related components, such as connectors, switches, power outlets, such as. 3. Priority placed circuit function blocks and the core component of larger components, and then to the core components placed around the circuit as the central component. 4. Power major components placed in the position in favor of heat, such as cooling fans, on the mainstream channel on the air if the use of heat conduction, should be placed near the slot chassis lead position. 5. The quality of the larger components on the board should avoid the center should be near the plate in the chassis side of the fixed place.
