Hi Jim,

Once did an experiment to see if the height of the solder could be controlled
over a period of time.  The experiment lasted for six months with height
measurements taken once every few days across a panel.  The results of this
experiment showed that you could not control the height of the solder joint
with any exacting tolerances.

Hi,

Can the Height of HASL be controlled?  I have seen the process but don't
remember exactly where there are any control points.

Thanks,
Jim West
