u"""刀片板 **1:1 打印稿**（A4 竖版 PDF + 600 dpi PNG），拿去和小米8 主板比孔位 / 侧键 / 排线槽。
|
||
|
||
/c/Python314/python .claude/r2/print_blade.py # 出 .claude/r2/print/blade_1to1.pdf / .png
|
||
|
||
- 数据全用**板上读回**：线 / 孔 / 元件 = 最终整板快照 `_blade_board_rot180_final_0911.json`，
|
||
焊盘 = `_blade_pads.json`（下发后 --dump 的），板框 / 孔 / 槽 = `pcb_blade`（和板上折线同源）。
|
||
- 上半张 **A 面**（手机那一面，正看）：板框 + 缺口、七个孔、两条槽、手机投影、K1~K4、金手指 B 排、A 面走线（淡）。
|
||
- 下半张 **B 面**（**从背面看、左右镜像**，和翻过来的实物一致）：元件本体 + 位号、焊盘、B 面走线（淡）。
|
||
- 两根标尺（横 80 mm / 竖 50 mm）：打出来量，不是 80.0 / 50.0 就是打印缩放了。
|
||
⚠ 打印一律「实际大小 / 100% / 不缩放」。
