My project has a lot of SMT components on the bottom face. I started a JLCPCB SMT assembly order using a pick-and-place file generated using the default options. All components are in the right place (no need to mirror coordinates) but are rotated 180 degrees. I do not know whether this is an EasyEDA or JLCPCB bug, but one could have an option to mirror the rotations angle for bottom components, checked by default. <br> The project is at   [https://easyeda.com/account/project/detail?project=d16853fa02744609adb2594b33fadbd2](https://easyeda.com/account/project/detail?project=d16853fa02744609adb2594b33fadbd2) Feel free to email me if you need the specific files. Thanks.
