SGA-8343X Reliability Qualification Report
V. Qualification Methodology
The Sirenza Microdevices qualification process consists of a series of tests designed to
stress various potential failure mechanisms. This testing is performed to ensure that
Sirenza Microdevices products are robust against potential failure modes that could arise
from the various die and package failure mechanisms stressed. The qualification testing
is based on JEDEC test methods common to the semiconductor industry. The
manufacturing test specifications are used as the PASS/FAIL criteria for initial and final
DC/RF tests.
VI. Qualification By Similarity
A device can be qualified by similarity to previously qualified products provided that no
new potential failure modes/mechanisms are possible in the new design. No other
products is qualified by similarity to this product.
VII. Operational Life Testing
Sirenza Microdevices defines operational life testing as a DC biased elevated
temperature test performed at the maximum operational junction temperature limit. For
the SGA-8343X the maximum operational temperature limit is 150
o
C. The purpose of the
operational life test is to statistically show that the product operated at its maximum
operational ratings will be reliable by operating several hundred devices for a total time of
1000 hours. The results for this test are expressed in device hours that are calculated by
multiplying the total number of devices passing the test by the number of hours tested.
VIII. Moisture Sensitivity Level - MSL Level 1 Device
SGA-8343X has successfully completed 168 hours of moisture soak (85
o
C/85%RH)
followed by three convection reflow cycles with a peak temperature of 270
o
C. The
successful completion of this test classifies the part as JESD 22-A113B Moisture
Sensitivity Level 1 (MSL-1). MSL-1 indicates that no special dry pack requirements or
time limits from opening of static bag to reflow exist for the SGA-8343X. MSL-1 is highest
level of moisture resistance that a device can be classified according to the above
mentioned standard.
