The leaded 16-pin SO package may be reflowed as

Handling, PC Board

Layout, and Assembly

The DS1340C 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. Exposure to reflow is limited to 2

times maximum. Ultrasonic cleaning should be avoided

to prevent damage to the crystal.

long as the peak temperature does not exceed 240°C.

Peak reflow temperature (≥ 230°C) duration should not

exceed 10 seconds, and the total time above 200°C

should not exceed 40 seconds (30 seconds nominal).

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 facto-

ry dry-packed.Handling instructions listed on the pack-

age label must be followed to prevent damage during

reflow. Refer to the IPC/JEDEC J-STD-020 standard for

moisture-sensitive device (MSD) classifications.

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 connect-

ed to ground.
