Hello, what is the right way to generate a pcb without copper (no traces, no copper surface), just pcb, with holes, soldermask and topsilkscreen (used as mechanic adapter)? I did one in the last weeks and uploaded it but the audit failed because easyeda did not produce all layers. After some email with the jlcpcb team the pcbs I finally got were exactly like I wanted them. To avoid discussions in the future I would like to know what is the best way to create such boards directly out of easyeda? regards
