How much can I expect the solder balls of a BGA package to shrink after reflow?

Description

You can expect the solder balls of a BGA package to shrink by about a third after reflow.

For example, if the solder balls have a height of 0.3mm before reflow, they will shrink to a height of about 0.2mm after reflow.
