PCB 布线指导

flux

可以帮你把 J8 这一路怎么走讲清楚，但我不能直接替你把 PCB 上的实体 trace 画出来并保存。从 Flux 的项目修改/布局技能说明来看，我能做的是布局检查、规则设置、布线优先级与约束规划；@layout 更偏向 inspect/setup/route 工作流控制，而不是直接持久化完成交互式单根走线 结合上下文工具说明，布局与原理图数据应通过结构化读取来分析现状，这也是我刚才对 J8 所做的方式
不过 J8 的连接关系我已经查清了，你现在可以直接按这个去走：
J8 端子定义

Table

引脚网络连接对象
J8 PIN1GND地网
J8 PIN2Net (J8 - PIN2)R8
J8 PIN3Net (U3 - VO)U3 输出电源网
我建议你这样布
  • PIN1 -> GND
    • 最简单，优先直接接地平面。
    • 如果 J8 附近已有完整 GND 铜面，就让 PAD 直接落地。
    • 如果地回路要穿过拥挤区，先打一颗就近过孔下到地层。
  • PIN3 -> Net (U3 - VO)
    • 这是电源线，优先级最高。
    • 这根线建议比普通信号更宽，尽量走最短路径回到 U3 输出网或该电源干线。
    • 少拐弯、少换层；如果必须换层，过孔数量尽量少。
  • PIN2 -> R8
    • 这是单独信号网，通常最后走。
    • 用普通信号线宽即可，优先避开电机驱动和大电流回路。
    • 如果 R8 在内侧，建议从 J8 PIN2 出来后尽快转到更空的一层。
推荐顺序
  1. 先走 J8 PIN3 电源
  2. 再处理 J8 PIN1 地
  3. 最后走 J8 PIN2 到 R8
当前已知约束
  • J8 在顶层，位置约 (-12.1 mm, 44 mm)。
  • 这个项目现在还有 69 个 airwires，所以 J8 附近不一定已经留出最终通道。
  • 当前基础规则已经收敛到最小线宽/间距 0.15 mm 级别，但 J8 的电源脚不建议只按最小线宽去走。
如果你要，我下一步可以继续把 J8 周围相关对象的位置一起查出来，然后直接给你一版更具体的：
  • 从哪个方向出线
  • 哪一层走 PIN2 / PIN3
  • 哪里先打过孔最合适
这样你就能几分钟内把 J8 这组线走完。
查J8周边位置
给具体出线方向
检查J8相关DRC
建议电源线宽
