See AN-450 “Surface Mounting Methods and their Effect
on Product Reliability” for other methods of soldering
surface mount devices.
Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage
to the device may occur. Operating Ratings indicate conditions for which the
device is functional, but do not guarantee specific performance limits.
