MIL-PRF-38535K
APPENDIX H
H.3 REQUIREMENTS
H.3.1 General. The qualifying activity (QA) shall evaluate the manufacturer's approach to the process baseline. The
manufacturer shall have a quality management (QM) plan specifying the characterization, certification, and qualification plans of
technologies and product (see appendix G). New technologies shall also be included and have a checklist defining the
necessary requirements for calculation/evaluation of failure mechanism, activation energy, characterization plan, qualification
plan and validation. The QM plan shall be submitted to the QA for approval (see G.3.3.1s). For class level S product, the
manufacturer shall evaluate the changes listed in table A-I in conjunction with the QA to determine if a change should be
classified as a new technology.
H.3.1.1. Characterization requirements. Testing performed with the intent to understand the technology part, materials, and
processes used to determine an item’s capability. The manufacturer should evaluate their process to determine the long term
reliability of the product. For class level S product, a detailed characterization plan identifying critical parameters, test
conditions, durations, required measurements, sample size, and temperatures shall be documented, including a detailed
physics-of-failure analysis considering mechanical, thermal, electrical, and chemical properties that could contribute to failures.
A failure modes effects analysis (FMEA) approach must be followed to ensure to the maximum extent possible that all
significant failure mechanisms have been defined and appropriate mitigation techniques have been identified.
H.3.1.2 Certification. Validation, by the QA, that the manufacturer has the capability of producing product which meets or
exceeds the requirements contained in this specification. The manufacturer shall document the certification plan as
documented in their QM plan. The qualifying activity shall be notified if deviations or exception are taken from the approved
plan.
H.3.1.3 Validation. Verification by the QA that the manufacturer has met or exceeded the requirements utilizing data,
demonstration, other approved techniques, or a combination thereof.
H.3.1.4 Transitional certification. Temporary certification (approximately 2 years maximum) given by the QA to manufacturers
working toward full QML certification (see H.3.3).
H.3.1.5 Qualification requirements. Evidence that the characterization testing and evaluations of failure mechanisms show
the technology meets or exceeds documented requirements. The qualification methodology will vary depending upon the
technology. The manufacturer shall document the qualification plan that is applicable to each technology. The qualification
testing for new technologies shall consist of standard military test methods as outlined in MIL-PRF-38535, MIL-STD-883, or the
QM plan as approved by the QA, including any tests deemed necessary by the characterization and physics-of-failure analysis.
H.3.1.6 New technology requirements. For class level B product, this is a product family, material, or process, that has never
been previously characterized and qualified by the manufacturer, and is detailed in the manufacturer’s new technology insertion
program (see 3.4.1.1.1 and 6.4.43).
For class V and class Y (class level S), this is a product family, material, or process, that has never been previously
characterized and qualified by the manufacturer for space applications, and is detailed in the manufacturer’s new technology
insertion program (see 3.4.1.1.1, 6.4.43 and B.3.9).
H.3.1.7 Mature technology requirements. A mature technology is one which the manufacturer has previously released to
production the techniques, materials, controls, design, and has a continuous reliability monitor plan in place to identify major
reliability life-limiting mechanisms and their associated acceleration factors establish activation energy, detect long-term product
shifts, and generate process data or established proof of stable process and/or equipment with negligible wear out
(see 6.4.44).
H.3.1.8 General QML process flows. The general QML process flows for new suppliers, and existing certified suppliers,
providing class level B products is shown in figure H-1, and for new suppliers, and existing certified suppliers, providing class
level S products is shown in figure H-2.
