Abstract
To evaluate the possibility of the partial melting soldering. wettability of partial melted solders was measured using wetting balance. Off eutectic Sn-Pb allows are wettable in their partial melting zone. Especially, Pb rich alloys showed excellent wettability while wettability of Sn rich alloys were adequate or poor. It is found that wettability increases over
