Subject: [TN] Copper Invar Copper and BGA's


> Dear TechNet,
> We have a requirement to design a CIC board using a 31mm x 31mm BGA.  I am
> concerned that if we design such a monster, we will not be able to replace
> the BGA at a rework station because of the high thermal mass of the core.
> Is anyone using BGA's on Copper Invar Copper boards?  Help!
