Hi, I just want to know the  way how to panelize my PCB for JLCPCB correctly if you are using the SMT assembly service? At first I followed this tutorial: [https://docs.easyeda.com/en/PCB/Panelize/index.html#Panelize-by-Editor](https://docs.easyeda.com/en/PCB/Panelize/index.html#Panelize-by-Editor) but JLCPCB replied that my pick&place file was wrong and my order was canceled. Do I have to follow the tutorial and choose **Panel by JLCPCB** at the order form at JLCPCB? Please show me the steps to follow for PCB panelization with SMT, my PCB looks like the PCB used in the tutorial.
