RS Shock Vibration - Scenario 1

You are here

Testing For: 
  • Connectors for electronic equipment
  • It applies when the product specification calls for a reliability growth program of equipment (electronic, electromechanical and mechanical hardware as well as software) or when it is known that the design is unlikely to meet the requirements without improvement
  • Solder joints, glued interfaces and other parts that are stressed by differences in CTE
  • Design for Reliability Processes - Early in the design processes, Highly Accelerated Life Testing (HALT) is utilized to expose early prototypes and existing components to the full range of expected operating conditions, within a controlled environment
  • This Handbook is intended for use by both contractor and government personnel during the conceptual, validation, full scale development, production phases of an equipment/system life cycle.
Standard: 
  • IEC 61014
  • IPC-9592A
  • DESIGN FOR RELIABILITY HANDBOOK TECHNICAL REPORT NO. TR-2011-24
  • MIL-HDBK338B
  • MIL-HDBK-344A
  • MIL-HDBK-2164A
  • MIL-STD-810G
  • MIL-STD-883J
  • MlL-STD- 1540C
  • Highly Accelerated Life Testing (HALT) Procedure - EAD-460/12/00
  • EMBRAER Quality Requirements for Suppliers
  • GM WORLDWIDE ENGINEERING STANDARDS GMW8287
  • Shenzhen Metrology and Quality (SMQ) Institute Guide for Defining and Performing Highly Accelerated Tests
Failure Type : 
F(v) = Failures accelerated by vibration (solder joint issues, mechanical issues, many others)
Stressor: 
RS shock vibration
Typical Failures Detected: 
  • High mechanical fatigue quickly weakens marginal mechanical design issues.
  • Vibration causes all components to resonate, resulting in maximum component displacement, and consequently, interference.
  • Fatigues weak and marginal designs very quickly.
  • Tests connector interconnects for integrity under stress
