Conclusion:
32 TSOP 8mm
The following qualification successfully meets the quality and reliability standards required of all Dallas
Semiconductor packages:
Package Description:
A description of this assembly can be found in the product data sheet. You can find the product data
sheet at http://dbserv.maxim-ic.com/l_datasheet3.cfm.
Reliability Derating:
The Arrhenius model will be used to determine the acceleration factor for failure mechanisms that
are temperature accelerated.
AfT = exp((Ea/k)*(1/Tu - 1/Ts)) = tu/ts
AfT = Acceleration factor due to Temperature
tu = Time at use temperature (e.g. 55C)
ts = Time at stress temperature (e.g. 125C)
k = Boltzmann's Constant (8.617 x 10-5 eV/K)
Tu = Temperature at Use (K)
Ts = Temperature at Stress (K)
Ea = Activation Energy (e.g. 0.7 ev)
The activation energy of the failure mechanism is derived from either internal studies or industry
accepted standards, or activation energy of 0.7ev will be used whenever actual failure mechanisms
or their activation energies are unknown. All deratings will be done from the stress ambient
temperature to the use ambient temperature.
An exponential model will be used to determine the acceleration factor for failure mechanisms,
which are voltage accelerated.
AfV = exp(B*(Vs - Vu))
AfV = Acceleration factor due to Voltage
Vs = Stress Voltage (e.g. 7.0 volts)
Vu = Maximum Operating Voltage (e.g. 5.5 volts)
B = Constant related to failure mechanism type (e.g. 1.0, 2.4, 2.7, etc.)
The Constant, B, related to the failure mechanism is derived from either internal studies or industry
accepted standards, or a B of 1.0 will be used whenever actual failure mechanisms or their B are
unknown. All deratings will be done from the stress voltage to the maximum operating voltage.
Failure rate data from the operating life test is reported using a Chi-Squared statistical model at the
60% or 90% confidence level (Cf).
In addition, Dallas Semiconductor's continuous reliability monitor program ensures that all outgoing
assemblies will continue to meet Maxim's quality and reliability standards. The current status of the
reliability monitor program can be viewed at http://www.maxim-ic.com/TechSupport /dsreliability.html.
The failure rate, Fr, is related to the acceleration during life test by:
Fr = X/(ts * AfV * AfT * N * 2)
X = Chi-Sq statistical upper limit
N = Life test sample size
The calculated failure rate for this device/process is:
The parameters used to calculate this failure rate are as follows:
Cf: 60%
Ea: 0.7
B: 0
Tu: 25
Vu: 5.5
C
Volts
The reliability data follows. Some of the data in this report may be generic. A the start of this data is
a description of the assembly vehicle used to generate this reliability data. The next section is the
detailed reliability data for each stress. If there are additional assemblies used as part of this report,
a description of each will follow which includes the respective reliability data for that assembly.
Where appropriate, preconditioning is performed before all stresses and the bond crater test unless
otherwise noted. The reliability data section includes the latest data available.
Failure Rates are reported in FITs (Failures in Time) or MTTF (Mean Time To Failure). The FIT rate
is related to MTTF by:
MTTF = 1/Fr
NOTE: MTTF is frequently used interchangeably with MTBF.
FITS: 3.0
MTTF (YRS): 37651
