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

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.
