One last one...

I have been working on 0603 tombstoning mostly from the pad stack/placement
point of view .

One nagging suspicion is that the solder is NOT melting at the same instant
on both the terminations . I want to analyse if the solder melting on the
two terminations of the 0603 is instantaneous or not . How can I do this ?
Are there thermocouples in the market with such resolutions which can show
this clear enough ? I am pretty new to the reflow technology stuff and would
like some recommendations on how to do this .


Regards,
Vishy
