SMT Board Assembly Process Guide - Intel
Pb-free Reflow Soldering Pb-free reflow requires relatively high temperatures, due to the high melting range of typical Pb-free solders. Typical Pb-free solder such as SAC305 (Sn/3Ag/0.5Cu) have s an initial melting point of 217°C and a final melting point of 220°C. Pb-free reflow soldering requires a narrow temperature range, in order

Current solder options are eutectic Sn/Pb or lead-free (98.2% Sn, 1.8% Ag) compositions. The solder bumped die is attached to a substrate by a solder reflow process, very similar to the process used to attach BGA balls to the package exterior.

When the assembly is heated in an oven, the solder paste warms and reflows. As the solder paste liquefies, it forms an apex at the center of the PCB pad. This apex must contact the terminal of the device

A water-soluble paste can be used if the residue can be adequately cleaned from underneath the package.
