Quality and Reliability Disrupted

Quality and Reliability Disrupted Abstract Dianna and Greg discuss your employability in the AI age.  So, let’s run a hypothetical.  You’re a 22 year old mechanical engineer.  You do robotic quality and reliability with a knowledge half-life of 4 years.   That means by the time you’re 26 knowledge in your domain has doubled.  Let’s say, you’re now 30.  Knowledge in your domain has quadruped.  Problem:  you have not updated your knowledge skills and abilities.  Are you still employable. Key Points Join Dianna and Fred as they discuss what we all face nowadays.  Technology is running ahead of our abilities.  And, how do we stay current?  Topics include: What is the half like of knowledge? What are examples of knowledge disruptions? How does it impact and why it matters to you? 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.

Keep it Simple

Keep it Simple Abstract Kirk and Fred discuss the challenge of using simple models for one finite element to extrapolate damage scalar metrics to very complex systems. Key Points Join Kirk and Fred as they discuss system models and how most fatigue damage models have many input variables, such as vibration and temperature, that can be very difficult to simultaneously measure across a system during operation Topics include: The vibration response of a test unit can be very different depending on how it is coupled or mounted on a vibration table. This is why it should be held so that the unit under test is mechanically coupled with the same boundary (attachments) as in its end-use chassis Most new electronics systems are iterations of existing products with new capabilities and features. Instead of reviewing and modeling the entire system for reliability weaknesses, we should focus on the few subsystems or components that have the highest risk from our knowledge of predecessor products and the field warranty data. CAD and Multi-physics computer models can run useful simulations of vibration and fatigue damage in the design phase. When you get the first hardware prototypes, the real testing and discovery of mechanical or electrical weaknesses can be confirmed or dismissed. The more stress margin, the higher the probability of being a reliable product in the customer’s use. Enjoy an episode of Speaking of Reliability.

Connectors

Connectors Abstract Kirk and Fred discuss the reliability of electrical connectors Key Points Join Kirk and Fred as they discuss the many ways that electrical connectors can lead to system failures. Topics include: The connector manufacturer may design a connector that is slightly modified from a standard reference design, which worked for many applications, but they cannot know the details of how it may be affected by your products’ end-use environments, such as higher thermal or vibration conditions in your system. Many connector issues are due to fretting corrosion caused by removing a typically thin gold-plated surface, which can be instantly cured when the connector is re-seated, making it very difficult to isolate. This phenomenon was a typical reliability issue with PC's DIMM memory modules when testing in an 85 °C and 85% relative humidity environmental chamber. High-speed digital systems connectors can have a significant impact on the quality of the signal integrity and lead to high Bit Error Rates (BER) if they're poorly designed or manufactured. There are so many parameters that the system designer may not be aware of when specifying a cable or connectors. How much does the cable/connector manufacturer know, or can know, about the specifics of how the cable works in your system and the details of system EMI, temperature, and tolerance to parametric variations?
