If you had to re-ball a BGA with 90Pb/10Sn non-collapsible solder balls, what would your peak temperature be? For reflow soldering processing purposes, what would your peak temperature be? If it was eutectic SnPb, I would anticipate the peak temperature to be about 215C for re-balling and reflow soldering.
