SOR 1029 Thermal HALT

SOR 1029 Thermal HALT

Thermal HALT

Abstract

Kirk and Fred discuss a paper Kirk wrote about how thermal HALT can be a tool for finding marginal signal integrity issues.

Key Points

Join Kirk and Fred as they discuss Kirk’s paper on the use of thermal HALT, initially posted on Kirk’s website, acceleratedreliabilitysolutions.com, in 2018, and a re-edited version that Fred recently posted on Accendo Reliability’s website. You can find a link to the article in the show notes below.

Topics include:

  • Kirk found little when he researched for information and data about how the physical electronics, especially the PWBA (printed wiring board assemblies) in high-speed digital systems, the variations in the board layers, and the surface roughness of the wiring traces affect the quality of the signal integrity (SI).  
  • As data bus speeds increase, effects causing errors in data transmission that were not significant at the time (when bus frequencies were in the megahertz range) became dominant at the gigahertz frequencies of today’s digital systems. Interconnect resistance, capacitance, and inductance are frequency-dependent, and as bus speeds increase and geometries continue to shrink, these variables may prove difficult– if not impossible– to model accurately.  
  • Thermal HALT and varying voltage and  clock margins may simulate the lot-to-lot parametric variations in semiconductors and PWBA’s, resulting in SI errors, but since few companies disclose their most useful methodologies, published data remains scarce

Social Dynamics with Yakira Mirabito (A Chat with Cross-Functional Experts)

Dianna Deeney interviews Yakira Mirabito about social dynamics within engineering and how it affects decision making. The episode focuses on improving design reviews and making them more inclusive.

Yakira explains how things like personalities and power dynamics can really affect decisions made by design teams. She gives advice to engineers on how to prepare for these reviews, such as how to give presentations effectively and encourage helpful feedback from team members. She also highlights useful tools, like the “Identity Wheel,” to help people understand each other’s backgrounds and avoid biases when making decisions. The episode is a great resource for anyone who wants to improve teamwork and create better products!

This interview is part of our series, “A Chat with Cross Functional Experts”. Our focus is speaking with people that are typically part of a cross-functional team within engineering projects. We discuss their viewpoints and perspectives regarding new products, the values they bring to new product development, and how they’re involved and work with product design engineering teammates.

About Yakira

Yakira Mirabito is a postdoctoral researcher at MIT whose work falls within design theory and engineering management. Her research examines how sociotechnical factors influence design decisions using quantitative and qualitative research methods. Her research interests include design behavior, cognitive biases, and social dynamics within engineering contexts. Yakira’s work enhances current design methods and tools, empowering engineers to build more innovative and equitable systems. She received her BS in Materials Science and Engineering from Northwestern University and her MS and PhD in Mechanical Engineering from the University of California, Berkeley.

Yakira and Dianna talk about

  • how social dynamics, cognitive biases, and power structures can influence engineering design reviews and decision-making processes.
  • recommendations for improving design review meetings through clear communication, inclusive facilitation techniques, and a focus on giving and receiving constructive feedback.
  • the need for engineers to develop self-awareness, particularly regarding their own biases and how their identities shape their interactions within teams.
  • how to effectively navigate feedback, especially from superiors, and the importance of justifying design decisions using evidence, requirements, and user needs.
  • the importance of democratic and inclusive design processes that value the diverse perspectives of all team members, including end users, and recognize the influence of power dynamics.

Yakira’s suggestions involve awareness and evaluating our decision making, including stopping to consider if the feedback we want to accept really links back to the objective results of our projects.

Fundamentals of Ongoing Reliability Testing

Fundamentals of Ongoing Reliability Testing

Fundamentals of Ongoing Reliability  Testing

podcast episode with speaker Fred Schenkelberg

Ongoing Reliability Testing (ORT) is a class of product testing that aims to identify potential field reliability issues after product launch and before customers experience failures. Typically, done using a rotation of samples directly from production and using expected use conditions/stresses, the testing balances many factors to be of value.

ORT works well to monitor an ongoing production process subject to variation. If that variation impacts reliable performance, then a well-designed and implemented ORT should identify the issue.

Let’s explore the range of considerations when designing an ORT to optimize the ORT’s ability to identify field problems efficiently. We will also discuss the various tradeoffs that impact sample size, the use of accelerating stresses, and more.
