Default EAGLE Cam processor and stuff...

I've never been doing this before so I have a few questions...
The files I have to sent to board manufacter are .cmp, .sol, .plc, .stc, .sts, .whl and .drd if I understood well?
How can I view those files after I export then?
Can anyone send .brd board for eagle that is compleated and have everything that is nessesary and that is ready for CAM procesor just to see how it looks like... If you have a picture of that board manufactured also that would be great!
What is soldering mask for?
What is aperture wheel file for?

Thanx!

Hi,

there are some free CAM viewers out there for checking your exported CAM data, i.e. GC-Prevue from GraphiCode http://www.graphicode.com, you can download it directly from here also http://www.pcb-pool.com/ppuk/service_downloads.html.

The solder mask prevent the solder from flowing where it should not flow, i.e. between pins of components, it also makes a PCB more reliable in humid environment.

Because in (much) earlier times photoplotters with pens were used, the aperture table describes the pens arranged in a penwheel used for plotting the board, it is a relict from former times. Newer formats like ODB++ don't need this.

If you use the standard Eagle libraries this is already done, the layers are tStop and bStop. If you only switch on these layers in the PCB editor you can see this. You have to use these Eagle layers to produce your CAM output for .stc and .sts (Stop-Component / Stop-Solder, i assume). Beware: The vias are also not covered!
