Level of experienced senior technician or engineer working on the quality or reliability of components, either at the manufacturing or selection level.

Technical or design office manager, engineer or project manager, reliability manager, test technician, test laboratory manager.

• Understand the objectives of component qualification testing, from the theoretical aspects of test definition (failure mechanisms, parameters and reliability laws) to the practical aspects of test execution (acceleration factors, sampling, etc.).
• Understand the main standards in force (MIL, JEDEC, AEC, ESCC, JESD, etc.).

Project Manager Engineer.

Projection and printed copies of Powerpoint presentations, practical case studies, exercises, situational examples, theoretical examples, video materials, etc.

5 working days before the start of the course (if OPCO funding).

INTRODUCTION

• Reliability definitions
• Failure, failure mode and failure mechanism
• Abrupt (catalectic) and wear failure
• Example of failure mechanisms
• Resistance/stress theory

SOME MATHEMATICAL NOTIONS

• Failure rate function l(t)
• Evolution of failure rate over time (bathtub curve)
• MTBF, MTTF
• Use of statistical laws and their limitations :
• Exponential
• Weibull

ACCELERATION LAWS / BUILDING A TEST PLAN

• Acceleration laws (Arrhenius, Coffin Manson and Norris Landzberg, Hallberg Peck …)
• Test plan construction and test sequencing
• Qualification of manufacturing processes

TEST PLAN DEFINITION METHOD

• Definition of product life profile
• Risk analysis (technologies versus life profile)
  • Components and technologies : PPAP…
  • Design
  • Industrialization
• Stress Based Testing (AEC Qxxx)
• Robustness testing
  • HALT
  • Development and implementation of a test plan
• Durability testing
• Review of the various tests proposed in the standards (definition and purpose of each type of test)
  • HTOL/THB/STORAGE/PC/TC/ESD/THB/T&H cyclic/mechanical tests, salt spray, etc.

SAMPLING

• Acceleration laws (Arrhenius, Coffin Manson and Norris Landzberg, Hallberg Peck …)
• Building a test plan and sequencing tests
• Qualification of manufacturing processes

MSL AND ESD LEVELS
