Hi,
I wont to clarify regarding the max weight for double side reflow, i
ment that there is a ratio between the surface energy and gravity, one
of the way to masure the adhesion is to test when does a melt droplet
is seperated from the solid surface, and with the use of Young-Dupre
equation you can calculat the surface energy.

Is there such a ratio between surface tension and gravity force ?
Where can I find it?
Thank you very much.
Best regards,
Victor
