Hi, Not sure if this is more of a Easy EDA issue or a JLCPCB one. To me it looks like Easy EDA is getting it right, therefore suggesting JLCPCB (well the web site) is doing something wrong. I've designed a few pcbs using easyeda. Recently I've got some made using the JLCPCB SMD service. So, I've exported my BOM and my Pick and Place files. However, in the JLCPCB parts review window, if I've used a WS2812B (LCSC part number C114586), it always has placement wrong and usually the rotation (more so if you have more than one of them). If I then look at the DFM analysis afterwards it also says parts (always the WS2812B ones) have been moved and usually rotated as well. Here's one I did recently :-  As you can see, the LEDS have all been moved and rotated. I just tried creating a simple circuit in Easy EDA with 4 C114586 and a connector. I created a PCB 50mm x 50mm with the centre of the board at -25mm X and 25mm Y. Then laid the 4 LEDS at -12.5 x 12.5, 12.5 x 12.5, -12.5 x -12.5 and 12.5 x -12.5. I looked at the pick and place csv file and it matches perfectly what I see on the screen. Here's what the 'Review Parts Placement' looks like :-  So far this has always been 'corrected', but surely it shouldn't be needed as the Pick and Place file is correct. So I'm not sure with the 'Review Parts' screen and more worryingly the DFM analysis is showing the wrong placement. Is there an issue between Easy EDA and JLCPCB? Many thanks Andy
