USB-C Temperature and Humidity Sensor Node Design

flux

已把板子放大到 90 mm × 90 mm，现在肯定放得下，且布线空间充足。
  • Layout 改为 90 × 90 mm
  • 仍保持 4 层板
  • 圆角保持 2 mm
  • 板边与 Keep Out 仍为 0.2 mm
现在的状态明显改善：
  • 元件总包围盒约 71.7 × 76.6 mm
  • 新板面积 8100 mm²
  • 元件占板面积约 18.3%
  • 已从“通道拥挤”变成“有比较充裕的布线空间”
下一步最合适的是继续做这两件事之一：
  • 重新整理器件分布，让关键连线更短
  • 继续针对 unroutable / airwires 做第二轮修复
如果你愿意，我就继续帮你压一轮布局，优先把相机、USB、电源、PWM 这几组再拉顺。
继续优化布局
处理布线问题
再加大板子
