Handling, PCB Layout, and
Assembly
The DS32B35/DS32C35 package contains a quartz tun-
ing-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 signal line. All N.C. (no connection) pins must be
connected 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 2x
maximum.
