Cold and Hot Dwells Scenarios using HALT
  • Scenario 1
    • Testing For:
      • Semiconductor devices
      • Crystalline silicon terrestrial photovoltaic (PV) modules
      • Solar Panel Testing
      • 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
      • Semiconductor devices
      • 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 61215

    • Failure Type :
      • F(d) = Failures accelerated by hot and cold dwells (particularly solder creep)
    • Typical Failures Detected:
      • Same as hot step.
      • As in Hot Step components contracting during cold, faulty solder maximizes chances of cracks at weak links.
      • Bearings, bushings tighten, showing areas most likely to be restricted.
      • Manufacturing errors that push tolerance stack up to one side or the other.
      • Components that don’t meet spec value or dynamic range.
      • Solder creep
    • Stressor:
      • Cold and Hot Dwells
    • Qualmark Accelerated Reliability System:
      • +200°C, -100°C at >70°C/min

  • Scenario 2
    • Testing For:
      • Assemblies (SRU) Equipment or Unit (LRU/LRM)
      • The tailoring process described in this standard (i.e., systematically considering detrimental effects that various environmental factors may have on a specific materiel system throughout its service life) applies throughout the materiel acquisition cycle to all materiel developed for military or commercial applications, including foreign and non-development item (NDI) procurements, procurements, or modifications of Allied systems or materiel, and cooperative development opportunities with one or more Allied nations to meet user and interoperability needs (DoDD 5000.1).*Note that this spec. is being revised specifically for HALT and HASS
      • For the purpose of this standard, the term “devices” includes such items as monolithic, multichip, film and hybrid microcircuits, microcircuit arrays, and the elements from which the circuits and arrays are formed.
