u"""载板侧键触点盘 J41~J60 的**定点重摆 + GND 盘扇出**（2026-09-07，顶针改中框式焊盘之后）。
|
||||
|
||||
/c/Python314/python .claude/pcb2_keypads.py # 只算：目标坐标 + GND 扇出候选
|
||||
/c/Python314/python .claude/pcb2_keypads.py --push # 只摆这 20 个盘（先删 GND 盘上的旧短线/过孔），读回核对
|
||||
/c/Python314/python .claude/pcb2_keypads.py --gnd # 重抓障碍表 -> 给 5 个 GND 盘各打一个过孔 + 短线（净距校核过才下发）
|
||||
|
||||
## 为什么不用 `pcb2_place.py --push`
|
||||
|
||||
它会重摆全部 218 个元件；导入变更后只有这 20 个盘换了封装、坐标要按新 `POGO_XY` 挪，
|
||||
其它元件一个都不该碰（碰了就要整板重布）。坐标仍从 `pcb2_place.plan()` 取 —— 事实来源不变。
|
||||
|
||||
## GND 盘的扇出
|
||||
|
||||
15 根 POGO*_* 信号由 `pcb2_route_sig.py --net ...` 重布（它整网删掉重画）；
|
||||
GND 是 `PRE_ONLY`，布线器不给它拉线，所以 5 个 GND 盘（J44/J48/J52/J56/J60）在这里手工扇出：
|
||||
盘心 -> 0.30 mm 顶层短线 -> Ø0.61/0.305 过孔，落到 Inner2 地平面。
|
||||
过孔放在盘的 **u− 侧**（触点菱形里 GND 本来就在最靠机身侧边那一角，那一侧没有别的盘），
|
||||
候选位置逐个过净距校核（对焊盘 / 过孔 / 两层导线，判据同 `pcb2_route_dp.CLR`）。
