The DS3231 package contains a quartz tuning-fork
crystal. Pick-and-place equipment can be used, but
precautions should be taken to ensure that excessive
shocks are avoided. Ultrasonic cleaning should be
avoided to prevent damage to the crystal.
Avoid running signal traces under the package, unless
a ground plane is placed between the package and the

ed to ground.
Moisture-sensitive packages are shipped from the fac-
tory dry packed. Handling instructions listed on the
package label must be followed to prevent damage
during reflow. Refer to the IPC/JEDEC J-STD-020 stan-
dard for moisture-sensitive device (MSD) classifications
and reflow profiles. Exposure to reflow is limited to 2
times maximum.
