Conclusion:
DS1961S
The following qualification successfully meets the quality and reliability standards required of all Dallas Semiconductor products and process:
sorrow是什么意思Module Description:
A description of this Module can be found in the product data sheet. You can find the product data sheet at /l_datasheet3.cfm.*Reliability Derating:
A module device consists of one or more IC's in a single, upward integrated, package. This package is asmbled to include batteries, crystals, and other piece parts that make up the
configuration of the Module. Becau of either the complexity of the package or the included piece parts, standard high temperature reliability testing is not possible. Therefore, in order to determine the reliability of module products, the reliability of each of the piece parts is individually determined, then summed to determine the reliability of the integrated module product. If there are "n" significant components in the module then:
Fr (module) = Fr (1) + Fr (2) + Fr (3) + ..... + Fr (n) Fr (module) = Failure rate of module
Fr(n) = Failure rate of the nth component
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 ud interchangeably with MTBF.
The calculated failure rate for this module/asmbly is:The parameters ud to calculate the module failure rate are as follows:
Cf:60%
Ea:0.7
B:0
Tu:25
Vu: 5.5

In addition, Dallas Semiconductor's continuous reliability monitor program ensures that all outgoing product will continue to meet Maxim's quality and reliability standards. The current status of the
reliability monitor program can be viewed at /TechSupport /dsreliability.html.

The reliability data follows. A the start of this data is the module asmbly information. This is a
description of the module. The next ction is the detailed reliability data for each stress found in the qualification / monitor. If there are additional process or asmblies ud as part of this report, a description of each will follow which includes the respective reliability data for that process/
asmbly. The reliability data ction includes the latest data available. Some of this data may be generic with other packages or products.
