Testing for Reliability & Performance

reliability testing halt services

Installing a reliability lab at your company without proper planning and an understanding of the cost considerations can be very expensive. To begin with, the total company sales dollars and the associated warranty costs dictate the magnitude of any plan.

This salary expense is the long‐term driver because the returns on investment, in terms of recovered warranty dollars, will take several years to recover. The current salary budget must be able to absorb these expenses for this time period. This is a minimum.

Installing a reliability testing lab at the company without proper planning and an understanding of the cost considerations can be very expensive. To begin with, the total company sales dollars and the associated warranty costs dictate the magnitude of any plan. This will guide the planner as to the number of personnel involved in the reliability process on a day‐to‐day, full‐time basis. This salary expense is the long‐term driver because the returns on investment, in terms of recovered warranty dollars, will take several years to recover. The current salary budget must be able to absorb these expenses for this time period. This is a minimum.

Then there are the other major expenses:

  • Equipment costs
  • Reliability lab space
  • Lab benches, desks and files, and so on
  • Support tools and equipment
  • Test equipment
  • Mechanical fixturing (between the device under test [DUT] and the chamber)
  • Dynamic test devices (to operate the DUT during environmental stress)
  • Consumables (power, materials, liquid nitrogen (LN))
  • Maintenance overhead

The reliability testing services will not, in and of itself, deliver all the savings to the bottom line, but it will be a substantial part.

To start with, one person must lead the activity. This person must have either the qualifications based on experience or be willing to hire the expertise needed to establish the reliability program. 

The reliability lab will not, in and of itself, deliver all the savings to the bottom line, but it will be a substantial part of it.

First of all, one person is needed to lead the activity. This person must have either the qualifications from other experiences or be willing to transfer current career ambitions toward reliability engineering. The latter will take a lot longer to grow. It is recommended that you seek someone from outside your present staff with the experience to build your lab and install the processes that will be utilized. The reliability engineer work will include the following:

  • A reliability engineering background
  • Highly Accelerated Life Test (HALT)/Highly Accelerated Stress Screens (HASSs) and Environmental Stress Screening (ESS)
  • Shock and vibration testing
  • Statistical analysis
  • Failure budgeting/estimating
  • Failure analysis
  • Conducting reliability training
  • Persuasiveness in implementing new concepts
  • A degree in engineering and/or physics
