Product Reliability Testing and Reliability Engineering

What is Product Reliability Testing?

Learn whether your product is dependable given normal and exceptional use in the real world. Before you invest your money for thousands of units, be sure you know that it works for as long as you need it to. Percept Technology Labs can answer the following questions about your electronic products:

  • How reliable is my product from failures when used by the general public?
  • Does my product last as long as expected?
  • My product won't fall apart easily, ending up as warranty nightmares, will it?
  • The cost effective components to use for any electronics product.

How does Percept test for product reliability?

Highly Accelerated Life Testing (HALT) can be a part of reliability engineering testing for electronic products. Every product will have failures at some point in the future. Completely eliminating failures would be cost prohibitive to build the product. Knowing this, design engineers search to build products within an acceptably small failure rate. To accurately test for product failure, reliability engineering testing determines the true failure rate and when in the future it will become unacceptable. This information should be used to support life claims and to design a more cost effective product.        Call today for a               FREE Consultation!                                                         303.444.7480               Back to Home Page            Back To Reliability Margins 

Reliability Testing Answers the Questions:

  • How does the selection of components determine failure rates?

Every component in a product has varying failure which contributes to a complete system failure rate. One of the reliability testing tools used by Percept, Mean Time Between Failure (MTBF),  can determine this theoretical failure rate.

  • Do we know which components are likely to fail? How can we discover which components are worth spending money on (and which are not)?

Since all components in a product contribute to its failure, engineers can control this contribution by selecting components with greater or lesser performance margin (and cost). This percentage can be determined by using the reliability tool called a Derating Analysis technique which will improve the overall success of the product over time.

  • Can we statistically prove the product lifetime without taking a lifetime?

Reliability engineers can design accelerated life tests that statistically shorten the life of a product so that its lifetime and failure rate can be determined.

  • Is it possible to “fail” a HALT test?

Highly Accelerated Life Testing (HALT) tests are one form of step stress test designed to systematically apply stresses until a product fails. Failure in a HALT test is a exactly what is expected to determine how long a product will last in the real world.

Percept offers a tailored reliability engineering program to support product design and qualification.

During the design stage, changes are easy to make and the information gained from the reliability program has tremendous value. Each of the tests in the suite provides information that allows engineers to make purposeful decisions about design components and configuration. Using Percept will ensure custom tailored tests to the detail of information that is required and to the constraints of budgetary requirements.
