PR5301-XX-TM - Package Dimensions
ODFN-4L-1.8x2.9 PACKAGE
A lead-free solder profile with a peak tempera-
ture of 260°C or less, according to J-STD-020
should be followed.
Samples shipped without moisture barrier bag
must be dry-baked according to JEDEC guide-
lines before soldering. Manual soldering may
not be possible or must be done with utmost
care.
Direct infrared heating should be avoided; pure
convection heating is recommended. There is
no experience with gas phase soldering.
