DirtyPCB notice:
Upload one or more PCBs on the order page. Gerber files should be inside a .zip archive with standard file extensions:
Gerber file extension	Layer
GTO	Top Silkscreen (text)
GTS	Top Soldermask (the 'green' stuff)
GTL	Top Copper (conducting layer)
GBL	Bottom Copper
GBS	Bottom Soldermask
GBO	Bottom Silkscreen
GML/GKO/GBR*	Board Outline*
TXT	Routing and Drill (the holes and slots)
*Required

These layers/files are typically needed to manufacturer a complete PCB. Only the Board Outline (GML/GKO/GBR) is required.
