[PCB_FORUM] Re: odb instead of gerber


We recently faced a big problem regarding the Shape in top & bottom layer
The copper pour in these layer showed perfect shape & no DRC error indicated.
Result of valor was reported to be same as that of cadence.

Fabricated board showed big copper shot with Component pad. However, CAM tool 
was
able to detect this.
Similar problem was reported by another design team.

I am in touch with local Cadence AE ,don't know if it's bug in Cadence or 
limitation
in valor.

I have been using ODB for the last 4 years, I currently work with a guy that
still generates gerber, netlist, readme files etc. It has been a much better
way to go.

Maybe this will be helpful to some. I know a lot of you already send odb++
to fab instead of gerbers, but i just now started.

I am still on the 1st one, so i have yet to see if any problems arise,
but here are some advantages for those not aware:

- There is only one file, and many fewer clicks to generate it.
- Importing into ViewMate is faster.  ViewMate is a free viewer.
- IPC netlist is included.
- Printing the drill file from ViewMate is much nicer (you see actual drill
size)

Some of these may be seen as just helping ViewMate, but that's what i use
here.
