Austin Reliability Labs Graphic: Life Predictions & Design Analysis

Life Predictions & Design Analysis

A good reliability prediction looks at the whole of your product and at each component piece. After all of the manufacturing specifications are analyzed, we can provide you with an accurate idea of your perspective failure rate and Mean Time Between Failure (MTBF) prediction. If your product is new, or you have made significant changes in the design, you may not have any field data to base your predictions on. In these cases, the accepted technique for calculating MTBF is to use the widely-recognized Telecordia or Military models. When you contract with ARL for Life Predictions & Design Analysis, you will receive:

  • MTBF Mean Time Between Failure
  • MTFF Mean Time To Failure
  • MTTR Mean Time To Repair
  • Availability & Maintainability
  • Reliability Prediction Types
    • MIL-HDBK-217F Reliability Prediction of Electronic Equipment
      • Part Count: failure rate of each part – quantity, inclues an environmental and quality factor
      • Part Stress: failure rate for each part – quanity, includes an environmental, quality factor, temperature and learning factor
