When the chips are packaged and tested, they must be assembled on mother boards.
Vapor Phase Soldering (VPS) uses the latent heat of condensation of Galden® PFPE vapors in order to melt solder paste and hence to obtain reliable metal joints.

Solder traditionally used ~ 60% of tin (Sn) and ~ 40% of lead (Pb). Now alternative solder materials have been introduced; the most common replacements for lead are silver (Ag), Copper (Cu) and Bismuth (Bi).

These alternative materials, however, bring a challenge: higher melting temperature.
Traditional tin/lead solders melt at ~ 180°C while lead free solder melts at ~227°C. Soldering temperatures are, as well as heating issues, ongoing concerns for PCBs assemblers.

Galden® PFPE LS / HS is a line of fully fluorinated fluids specifically designed for the VPS process. The narrow molecular weight distribution as well as the very strong carbon-fluorine bond and the flexible ether link provide the properties which make Galden® PFPE LS/HS ideal for use in VPS.

Galden® PFPE LS and HS fluids precise vapor temperature eliminates overheating, offering the widest temperature range to lead free solders up to 260°C and are RoHS compliant.
