"""生成 KiCad 封装库 kicad/lib/PhoneRail.pretty/*.kicad_mod。
|
||||
|
||||
来源：EasyEDA 工程包里的 .efoo。**必须**从工程包转，不能用 easyeda2kicad 按 LCSC 拉 ——
|
||||
本工程有一批自制封装（触点盘 PAD-D1.5_MI8-KEY、BM24、BAT-FPC 等）根本没有 LCSC 料号。
|
||||
|
||||
单位：EasyEDA PCB 用 **mil**（实测 C0402 焊盘 19.685 mil = 0.500 mm、间距 0.84 mm）。
|
||||
Y 轴：PCB 侧两边都是 Y 向下，**不翻**（只有原理图才需要翻，见 k_gen_sch.py）。
