I found this in the FAQ **7\. I want to order more than 30 pieces\, what can I do?** You can panelize your boards to realize a quantity of more than 30 pieces, please note there is a panel size limit of not bigger than 200x200mm. My PCB is 180 by 44mm so it isn't going to get more than 4 per panel but I need 500 units. Does JLCPCB not do large quantities of SMT assembly ?
