Training Options

Training Options Abstract Kirk and Fred discuss the evolution of ways to learn reliability and failure analysis with so much information available on the internet. Key Points Join Kirk and Fred as they discuss the many different training options for understanding reliability issues Topics include: Internet searches can now provide access to many different sources of information, from books to videos on how to discover and repair many types of consumer products, but the best understanding comes from disassembling the failed system and seeing the real causes. YouTube and other online sources, such as Reddit and Google, can quickly show how to go about troubleshooting a failure and how to repair, which may be better than any user manual from the manufacturer Online AI tools such as ChatGPT can provide a vast amount of training materials, although it currently sometimes fabricates some information, so it cannot always be trusted. AI tools are very dependent on how a query is made, and your own understanding of the basics of the subject you are researching, and much of the material and previously published material  that the Large Language Models  AI uses may be wrong Enjoy an episode of Speaking of Reliability.

Failure Mechanism Awareness

Failure Mechanism Awareness Abstract Kirk and Fred discuss the many different failure mechanisms and the need for understanding the failure mechanisms and causes of failures. Key Points Join Kirk and Fred as they discuss why it is necessary to have an understanding of material science and the physics of failure mechanisms to do a thorough failure analysis. Topics include: We expect our vendors and all of the long chain of their material suppliers to provide  a reliable component consistently, but sometimes they are unaware that their own suppliers have a production excursion Sometimes a new failure mechanism is discovered, similar to what Kirk discovered about extremely pure water used for cooling in an Ion Implanter used in semiconductor manufacturing, when a leak dripped onto a PWBA. IC manufacturers have proprietary formulas for encapsulating the die, but any of their chain of material suppliers can lose process control, which results in a latent defect that can lead to failures in many different products using that component.

Overcoming Product Protections for HALT

Overcoming Product Protections for HALT Abstract Kirk and Fred discuss turning off the built-in over-temperature production circuits to perform thermal HALT. Key Points Join Kirk and Fred as they discuss the methods for testing the empirical thermal limits of a power supply or circuit board. Topics include: If possible, the thermal over-temperature protection (OTP)  devices should be disabled, but it may not be possible, and we discuss the potential options for overcoming these limits. CPUs in PCs all have a thermal diode shutdown circuit built into the CPU die, but the manufacturer will not provide the code to override it, so an alternative was to use a water-cooled heat sink cooled from outside the chamber. The empirical limits found in a HALT should not be shared with all the internal departments, as it might be mistaken as a safe operational range if it is disclosed to the marketing department. HALT is based on the strength of materials and the fundamental limits of the current technologies, and not the end-use conditions or environments. Thermal HALT on a product that still has a thermal OPT only tests one device, the OTP, and you will not discover the real distribution of margins and strength of multiple samples.
