[PCB_FORUM] Re: Copper balancing "thieving dots"

There should be no reason to have the thieving on other than the top and
bottom, unless your board house is running some sequential lamination stuff
(i.e. buried vias and such).
 
I had done some work on the shareware balancing program originally written
by David Sheuring in 1984 to adapt it to some of the things we do here,
adding "thieving keepout" areas,  and the ability to automatically remove
the thieving.  It takes about 30 seconds to balance a side on my current
board using the skill routine,  it's been 4 minutes or more for the built-in
Cadence routine and it's still not done.  I don't know what else it is
checking for, but it certainly is slooowwwwwwwwww...
 
I think I'll still use the  skill routine  :)
 
I think the original still on sourcelink, my version probably wouldn't work
outside Tektronix.

It's my opinion, not Tektronix'

It looks like this will be a very useful utility. One more question: Can
anybody tell me if it is better to have copper balance pads aligned or offet
from layer to layer?

Thanks for all your help!

Is there a list of all Allegro commands available? 

    



Yes,  Tools->Utilities->Keyboard Commands.

Uri,

Thanks a lot!

I could not find anything in Allegro Help.

It looks to be exactly what we were looking for.

Is there a list of all Allegro commands available?

There is an Automatic Copper Balance PDF on Source Link, but looks like 

a skill file that would have to be loaded independently.

We will give your suggestion a try Uri.



Thanks again,

Mark

Does anybody know of an easy way to create (in Allegro) copper balance

thieving dots?

We are instructed to balance all boards in the database and not to give

    



  

fab free rein in their placement.

We are currently adding 100 mil shapes on 200 mil spacing...manually.



Thanks,

Mark
