HANDLING, PCB LAYOUT, AND ASSEMBLY
The DS1338C 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. Exposure to reflow is limited to 2 times maximum.
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.
The RoHS and lead-free/RoHS packages may be reflowed using a reflow profile that complies with JEDEC J-STD-
020.
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.
