HANDLING, PC BOARD LAYOUT, AND ASSEMBLY
The DS1337C package contains a quartz tuning-fork crystal. Pick-and-place equipment may 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 connect) pins must be connected to ground.
Moisture-sensitive packages are shipped from the factory 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 standard for
moisture-sensitive device (MSD) classifications.
