Hello ; About the JLCPCB SMT assembly, please consider the minimum and maximum panel size while preparing your design :  2 Layer board:Min 20mm×20mm Max 480mm×320mm _·_ 4 Layer:Min 20mm×20mm Max 350mm×320mm

@JLCPCBsupport Thanks for the reminder, my panel does fit within those constraints.  As for my question, is there a way to automatically panelize where I specify different numbers of the individual boards, or do I just need to manually place things? Also when I panelize it do I get a single panel or am I purchasing 5, 10, 15, etc. panels?

@lifewithmatthew About how to add different PCB designs in one panel with different PCB quantity for each design, I think that @UserSupport could help more in this. I don't think that this could be achieved automatically but probably you need to duplicate the designs regarding the quantity for each design in your schematic and make a PCB design related to that schematic and then you can have the automatic panel generated from that specific PCB design. About placing the order from JLCPCB the quantity setting will be all the same 5, 10, 15 etc. **ONE MORE IMPORTANT NOTE : ** > Some customers would like to merge more than 1 PCB in the same Gerber. We know you want to save money but this may make it hard to cut the board outline and more importantly, this will take a lot more time to pick up and package the PCB. Although by doing this, you just have the one order, this complicates the fabrication of the panel and separation of the individual PCBs, so we will usually charge more for this. Similarly, using holes or slots as break off sections between boards are treated the same way as putting more than one design on a panel, each with its' own board outline.

Yep,  you need to panelize manully if you want to panelize different PCB [https://docs.easyeda.com/en/PCB/Panelize/index.html#Panelize-by-Manually](https://docs.easyeda.com/en/PCB/Panelize/index.html#Panelize-by-Manually)
