Hi,
 
We are having a PWB wherein, we have a potentiometer and 3 PLCC package on the bottom side of the PWB.
 
I need help to know if there would be issue of  these components falling off during the second reflow process (when top side is being reflowed)?
 
We not have options to move these on the top side as there are already other PLCC and BGA packages eating up the PWB land area.
 
Let me know your comments and also on how can we prevent these from falling off during the second reflow process?
 
I am attaching the data sheet for both these parts above.
 
Thanks, in advance to all of you for your help and precious time.
 
Rgds
Prashant
