Hi all. I would like to realize a PCBA on JLCPCB. I have a only one SMT reference on the bottom side of my PCB. On JLCPCB Review Parts Placement viewer, all of them are shifter as you can see here : ![fuck.png](//image.easyeda.com/pullimage/0fANGd3vXTZF9ngIVWwJ4UdQS6E0mEzoRumTdnMy.png) My Gerbers and pick and place files come from EasyEDA directly without modification. I don't understand why the SMT are shifted and the JLCPCB is not very helpful.
