Outline

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

this is for human read, can not be used
this is for human read, can not be used
This is machine read, correct format can be used
check the drill file, standard NC format: .DRD, .TXT, .DRL. Excellon/NC Drill file with 2.4 trailing format.

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.

www.pentalogix.com/viewmate.phpViewmate is best the we like, simply open the software, importing from directory, the tool will automatically read all the gerber files and display. You will need to register on their site to get the serial code when installing the software, if you already have then you can feel free to download from somwhere else like softpedia.
GC-Prevue, Another freeware Gerber view tool
The online gerber view - http://mayhewlabs.com/3dpcb.
zofzPCB - provide very good 3D visualization.

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:

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*	-
Protel	GTL+GBL	GTS+GBS	GTO+GBO	GTP+GBP	txt (or Drl)	GKO, GML or GM1
Orcad	top+bot	smt+smb	sst+ssb	spt+spb	thruhole.tap	-

Note:

Mre similar files:

3. make vias more elegant, no stop mask, 0.3mm diameter
4. add full ground for board, set grade to 6, thermal off, no orphan, added more ground vias if necessary
5. build a seperated mechanical layer to export.
6. make sure board edge is fully stacked together.
