Hi Ramakrishnan,

1. Solder dip test tells about  the WETTABILITY.

2. Floating test tells about the ALIGNMENT

Typically 1. is performed on just a few coupons and NO components, while 2.
is done with many coupons (or PCBs) and WITH  components. For getting good
statistics it's not unusual with 10,000 components.
