1. Gerber Files Required:The following files would be needed for the 2-layers PCB production:
Top layer: pcbname.GTL Bottom layer: pcbname.GBL Solder Stop Mask top: pcbname.GTS Solder Stop Mask Bottom: pcbname.GBS Silk Top: pcbname.GTO Silk Bottom: pcbname.GBO NC Drill: pcbname.TXT Mechanical layer : pcbname.GMLNote:
- The Gerber file must be RS-274x format, The format of the drill file can be Excellon
- Board outline must be included at least in one layer if there isn't GML/GKO layer.
- All the holes will be plated by default, if you need some holes not plated, please name the non-plated holes as pcb.name-NPTH.txt and leave a comment;
- For one layer PCB, If you need the solder mask on the top and bottom side, please order it as 2 layer PCB and leave a comment '1 layer PCB with solder mask both side".
