Common Gerber File Problems


  • For this reason, the manufacture will not how to cut it, even you have all the copper trace, holes, via, etc, correct, but the PCB still won't have a shape, this is impossible for manufacturing.

Drilli Format

  • Follow file read in viewmate

  • If your file is missing the T01C0.787... etc. It will can not be used.
  • These are the drill sizes and are required in the header. Note: some software will include "inline" tool sizes - which means that they are not in the "header" information at the top of the drill file but are scattered through the file just before the tool is used. This is also ok - but they must be somewhere!
  • Open your own drill file and check to see that the drill sizes are included at the top of your file. 2.4 trailing is what we use, but any format (2:3 leading, 1:5 none, etc) is OK! If it can be imported, we'll get it imported - however you may notice that the drill file looks strange during the upload since 2:4 is the default for rendering the image.

Gerber View Tool

Use with Gerber view

Gerber Required File List

  • Signal copper layers: Top layer, Bottom layer, Maybe medium layers optional
  • Soldering Stop mask layers: Top and Bottom
  • Silk screen layers: Top and Bottom
  • Drill layer and Outline (Dimension) mechanical layer:
  • Drill drawing: we call the hole character, different holes with different symbols, some still indicated next to the symbol corresponding to the pore diameter and pore number.
This is used to check the NC drill, and normally for human reading.
  • NC drill: we call drill with, see the graphics are solid (as solid round, solid oval), for practical file, and used by machine directly

The Following files are optionally:

  • Solder paste : Top and Bottom, Only for making stencil.

Gerber File Extension List

We are only accepting the following file extensions:

Format Top & Bottom Copper Top & Bottom Solder Mask Top & Bottom Silk Top & Bottom Solder Paste NC Drill Outline / Mech / Keepout Layer
Eagle cmp+sol stc+sts plc+pls - drd, + dri* -
Orcad top+bot smt+smb sst+ssb spt+spb thruhole.tap -


  • The "*" file may not very necessary.
  • Dri (For eagle) - Drill Station Info File
  • Drl (For eagle) - Excellon Tool List

Mre similar files:

  • gpi - gerber plot information (not really useful)
  • MiddleCopper 1-99
