Applying Design of Experiments for Selection of Materials and Components in Product Development

A reliability-based experimental design can help select the most robust materials, components and configuration for improved product reliability. This presentation covers the stages of Design of Experiments (DOE) starting with screening, then selecting and optimizing the solution and, finally, verifying the solution with accelerated testing. An example used to illustrate the approach is presented, showing a sensor assembly design modification to provide longer life in a severe temperature and humidity environment. A reliability DOE analysis was used to determine the effect of component, material and process factors on the time to failure in an accelerated temperature/humidity test as the response. The selected design configuration successfully completed the accelerated test to achieve customer expectations for the life of the product.

Key Words: Design of Experiments (DOE), Design for Reliability, Accelerated Test, Product Development, Reliability DOE, Robust Design, Design Verification
