Using DFR Tools
Join Kirk and Fred as they discuss the use of DFx, being design for tests, design for manufacturing and design for reliability and the basics of good designs.
- There are many CAD tools that have existed, such as SPICE for circuit analysis, that have been improved significantly over the decades. There are also powerful multi-physics software packages that can simulate environmental stresses on designs that can be applied before actual hardware is built.
- “All models are wrong, some are useful” a quote from George Box is true about the CAD models in that the values used are averages of well manufactured components and do not account for the manufacturing variations or variations of the same component from different vendors.
- It is important to document the weaknesses found in development of a new product to prevent future design weaknesses in the next iteration of the product or a new product to become more efficient in reliability development. Companies that do frequent reo0rganizations can make this very difficult to transfer the lessons learned to a new reliability team.
Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques to field data analysis approaches.
