Управление Вакуумным Насосом

flux

Сейчас у тебя есть схема в проекте Flux, но готовой платы для производства ещё нет.
Проект здесь:
/lilg/dental-vacuum-pump-controller
Что уже сделано:
  • собрана принципиальная схема контроллера;
  • добавлены питание 24 В → 5 В → 3.3 В;
  • STM32 как “мозги” вместо PLC;
  • RS485/Modbus к Yaskawa GA500;
  • входы 4–20 мА;
  • PT100 через MAX31865;
  • float-входы;
  • выходы на соленоид и alarm;
  • OLED-дисплей;
  • SWD-разъём для прошивки;
  • ERC по логике схемы очищен.
Но чтобы начать производство, нужно ещё сделать:
  1. Закрыть BOM
    • подобрать реальные MPN для всех generic резисторов/конденсаторов/индуктора/OLED;
    • проверить доступность компонентов.
  2. Финализировать схему
    • подтвердить клеммы GA500 GA50UB010EBA;
    • подтвердить, нужен ли 4-контактный или 5-контактный VFD-разъём, потому что для RS485 желательно иметь D+, D− и AC/shield/common;
    • подтвердить датчики 4–20 мА и соленоид.
  3. Сделать PCB layout
    • задать размер платы;
    • разместить компоненты;
    • развести дорожки;
    • проверить DRC;
    • проверить зазоры, токи, зоны 24 В, изоляцию RS485.
  4. Сгенерировать производственные файлы
    • Gerber;
    • Drill files;
    • BOM;
    • Pick-and-place;
    • желательно PDF-схему и сборочный чертёж.
Итог: схема есть, плата ещё не разведена.
Чтобы получить от меня “готовый результат для производства”, следующим сообщением напиши:
“Продолжай до готовых Gerber/BOM для производства”
После этого я пойду дальше: сначала закрою BOM/MPN, затем сделаю layout платы, проверю DRC и подготовлю файлы для изготовления.
