Quality & Reliability for High-Reliability

TI HiRel is your source for High-Reliability Digital Signal Processing (DSP), Analog & Mixed Signal, Logic, Interface, FIFO, and PAL solutions for military electronic, avionic, high temp, and space applications

In this area you will find links to quality and reliability related information. TI's HiRel Defense & Aerospace is certified as a MIL-PRF-38535 QML supplier by the Defense Supply Center Columbus (DSCC).


Military & Space

HiRel Product Nomenclature

Here you will find an explanation of the part numbering system and package marking for various HiRel product families.


HiRel Hermetic Product Package Material Content

This report contains the product content for the HiRel Hermetic/Ceramic devices organized by package type and in-count.


A Paper on Upscreening of Class B Microcircuits for Space Applications

TI offers an extensive line of Class V devices qualified for use in space applications. This whitepaper describes the pitfalls of attempting to use non space-qualified devise in these critical applications.


DSCC Class Q & V Certification

TI is certified and listed on the Defense Logistics Agency Qualified Manufacturer Listing for Class Q and Class V products. This links to a copy of that certification.

EP Reliability Information


An example EP product Reliability Report

In response to customer needs, TI released the Enhanced Product (EP) family. EP provide a means to facilitate, not replace, OEM qualification of COTS devices through baseline control and enhanced qualification pedigree. To support those customers using TI EP in critical or harsh environments TI publishes derating tables and extended product reliability reports. These reliability reports are available in the product folder or here:


Plastic Encapsulant Impact on Au-Al Ball Bond Intermetallic Life

This paper explains the process for determine the reliability of gold-aluminum wirebond systems in plastic packages. It is especially of interest to those customers concerned with extended high temperature operation or long term dormant storage.


COTS Journal Article: Beyond Quality - Assuring the Reliability of Plastic Encapsulated Integrated Circuits

Uprating and upscreening commercial components to extended temperatures are dangerous practices that can adversely affect reliability and maintainability. Instead, look closely at the IC manufacturer’s fabrication, assembly and qualification process, policies and procedures.


COTS Journal Article: Reliability Implications of Derating High-Complexity Microcircuits

It’s now common practice to upscreen COTS components for use in harsh environment military systems. But while derating ICs in order to make them work outside of the manufacturer’s data sheet feels like a safe way to ensure reliability, there are some downsides that system designers should consider.

QML Q & A

What does QML mean?
Qualified Manufacturers List
Is QML a military specification?
No. QML is a performance base specification, MIL-PRF-38535.
Where do DSCC SMDs, JAN and SNJs fit under the QML umbrella?
The SMD, JAN and SNJ specifications now define the electrical performance specification for the particular device. These devices may now be built using the QML (MIL-PRF-38535) as the process performance specification.
What is Best Commercial Practices and how does that relate to QML?
Best Commercial Practices is a term applicable to any business product, process or system. It implies the elimination of non-value added steps.
QML allows a supplier with significant statistical data, to eliminate process steps which do not add value to a process flow.
How can I tell if the processing of a device has changed under QML?
All TI Military devices, with the exception of mil-temp (SN/SM) and plastic, are shipped with a Process Conformance Report that shows what processing the devices received.
How does TI decide what process steps should get eliminated from a device flow?
TI first collects significant statistical data proving a given process step is not adding value to a device flow. With the agreement of the Technology Review Board (TRB), the process step can then be eliminated. ex. 216,670 HC/HCT devices were tested at -55 with zero test related failures. -55 is no longer performed on HC/HCT devices.
