When deciding where to place thermocouples, be careful about jumping to 
the conclusion that the centre ball is going to be the coolest. Depending 
on the relative sizes of the BGA substrate versus the overmoulding, you 
may find the outside balls to be cooler. It is safest to thermocouple 
both centre and corner, as well as the top of the package.
