Is There a Standard for HALT?
Join Kirk and Fred as they discuss a topic that has been an ongoing discussion since they began the Speaking of Reliability series started many years ago.
- Standards are many times used to get specific test procedures completed by vendors. Making vendors contractually complete HALT is the worst way to have a vendor discover and understand the usefulness of HALT methodology.
- Kirk has observed that at least one sample of an Arduino microprocessor has demonstrated operation without failure for hours at 200 deg C.
- Standard test methods remove much of the engineering judgement, or actually thinking about what and why a test process is being performed.
- Fred provides an example of using a standard test procedure that has never failed and caused much waste without thinking about the reasons the test should be performed.
- At some point HASS becomes a poor return on investment, and should not be continued on a mature manufacturing process.
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.
