Dear Valued Customer;
SiTime products are backed up with a warranty of one year from the date of our invoice. Recently we have
被asked whether there are any date code restrictions on this warranty, and after investigations we have
concluded that SiTime is able to extend this warranty to all products shipped by SiTime, regardless of date
code at
time of
shipment.
SiTime
is
able
to
offer
this
warranty
because
of
the
strength
of
our
advanced
packaging technology.
All SiTime products use a lead frame plating composition of nickel-palladium-gold (NiPdAu) that ensures
good solderability
over
a
long shelf
life.
Early
adopters
of
NiPdAu
plating
finish
have
estimated
the
shelf
life at approximately eight years. In addition, the pre-plating capability of NiPdAu allows the elimination
of messy
electrochemical
plating lines
during
the
manufacturing process.
These
are
two
of
the
main
reasons for our choice of NiPdAu as a plating standard across all SiTime products.
SiTime oscillators
are
also
insensitive
to
moisture
incursion.
All
package configurations
have
被
thoroughly tested and they have passed the JEDEC Moisture Sensitivity Level One (MSL 1) without
delamination. SiTime’s
Package
Development
Team
has
closely
worked
with
our
manufacturing
subcontract partners to bring this capability to our products so that our customers can be assured of long
shelf life without worry of the popcorn affect during soldering.
我们的广告vanced packaging gives our products long shelf life, making the old concept of a date code
restriction no
longer
relevant.
We
therefore
request
all SiTime customers
to accept
all products
shipped
from SiTime regardless of date code, with this assurance that all products are fully covered by SiTime’s
manufacturing warranty.
Please contact your SiTime sales representative if you require more information.
Sincerely,
Cyrus Mehr
Director, Operations and Quality
