"I want to connect copper to aluminum (GND) How can i do it ?" You can't do it in the editor. You have to design your PCB using the Top Layer only. If you really need to connect the top copper to the Aluminium then you can add Top layer through-hole pads and use bolts to connect the two layers. You may have to find a way to ensure that the bolts connect to the aluminium such as by using countersink head screws or start washers. Note that this is not supported by JLCPCB. Please note that you asked exactly the same question 5 months ago and it was answered here: [](
