Petrified, I think your Assembly/Packaging Group should simply provide you with the data if you're from the CS group. Your task is to relay the data to the customer, not to acquire the data. So my suggestion is for you to request the said data from your Assy Dept.

Thanks,

Can you clarify what you mean by this: "Thermal Conductivity of Pb for BGA, TQFP and PLCC"?

Or are you just looking for the thermal conductivities of these packages? Maybe you can start with this: http://www.semiconfareast.com/theta.htm
