[PCB_FORUM] Re: rooms and areas (beginner with performance)

Dave,

 

I build the Constraint Area into the BGA library part, and assign the
NET_SPACING_TYPE and NET_PHYSICAL_TYPE (= BGA) there also.

That way, it does move with the BGA symbol, even if you modify its
extents.

 

Also, "sjchar3" (name?), it sounds like you need to talk your employer
into some formal training!

 

Good luck!

 

Gary

I have always used a Constraint Area for this. And assigned the
appropriate

Spacing and Physical constraint sets. Only trouble is that the
constraint does not follow

The component when moving. You can create a Alternate and lock it in
place that way.

group: I have a BGA and I would like to route 4 mil trace between pins,
and only a certain via would be used in this location. The rest of the
board is 8 mil traces. Do i set up a room, area or region?  

Thanks Austin for you earlier reply.

Thanks again.
