     Thermal mass relating to....? Process assembly profiles, thermal 
     design simulation, rework, etc. Please provide some additional detail.

Hi,
     
How do people claim the existence of thermal mass issue?  
     
Say if I have a PWA with large and small components.  Do I measure the 
surface temperature of those components and relate the issue to the 
temperature discrepancy?  OR do I measure the temperature underneath the lead 
(or even the bottom of the components)?
     
Thank you very much.
     
Regards,
Victor
