Do it Right the First Time

Abstract

Kirk and Fred discuss the risks to reliability of having to rework or human handling of circuit boards and rework in general.

Key Points

Join Kirk and Fred as they discuss process control and hand soldering and how it increases the reliability risk compared to the original production line produced circuit boards

Topics include:

• Reworked solder joints are inconsistent and human touch-up carries a greater risk of failure than the original re-flow oven soldering.
• Rework and repair are often referred to as the hidden factory as the costs of touch-ups and failures of the rework are not always financially accounted for.
• A fundamental tenet of reliability engineering is that if you do not know the physics of why a system fails and why it's unreliable, you will not know how to make it reliable
• Customers, in general, expect more reliable products, and the smartphone industry has made them more shock-resistant and water-resistant in each new iteration of the design.

Moisture Failure Mechanisms

Abstract

Join Kirk and Fred  discuss failure mechanisms caused by or accelerated by moisture.

Key Points

Join Kirk and Fred as they discuss how water, especially saltwater, can cause failures.
Topics include:

• Even if you think making an O-ring seal in outdoor equipment will keep moisture out, it will still leak enough over time to equalize the external moisture level. Every seal leaks; it is just a matter of time to change the rate of leakage as seals degrade
• Moisture in component encapsulations can cause popcorning in re-flow, which isn't immediately detected but makes a small crack that will eventually fail from moisture intrusion.
• Frozen water in the form of hailstones striking solar panels is a potential cause of failures that they must be able to withstand.
• Even though automobiles are designed to withstand all kinds of rain and other environmental extremes, the hurricanes hitting Florida and North Carolina have flooded many cars, which are not designed to withstand water immersion, resulting in many time dependent latent failure mechanisms.
• Humidity is sometimes increased in dry climates such as here in Colorado for electronics  printed wiring assembly manufacturing to reduce the risk of ESD damage

Two Approaches

Abstract

Chris and Fred use the safe return of the Boeing Starliner … without the crew! What does this tell us about its safety and reliability?

Key Points

Join Chris and Fred as they discuss the recent incident involving the Boeing Starliner crew module that managed to get a crew to the International Space Station (ISS) but was not deemed safe enough to return them. But it has since ‘safely’ landed. So was it safe? Is it safe? What about reliability?

Topics include:

• Russian roulette is ‘safe.’ If by safe that means that there are outcomes with no undesirable outcomes. Russian roulette (depending on who you ask) involves a single bullet being placed in the cylinder of a revolver (gun). The cylinder can hold six bullets. The cylinder is then spun so that there is a one in six chance that a bullet will be fired when the trigger is pulled. So there is a five in six chance that no bullet will be fire when you pull the trigger. So does this mean that Russian roulette is safe five times out of six and unsafe the other time? NO! It is always unsafe because it is all about the PROBABILITY of something bad happening.
• Is Boeing ‘safe’? No. NASA’s Inspector General has been very critical of Boeing’s ability to safely, efficiently and effectively develop spacecraft. Issues include not having enough people, not having enough of these people appropriately trained, not responding to corrective action requests from NASA and LOTS of others. Why? Well, while Boeing does have a history of space exploration dating back to the Apollo program, that history is dated. And no longer relevant. So Boeing won contracts from NASA to build spacecraft and THEN tried to create a team to build it. Compare that with SpaceX, which is much younger, but was established with the unambiguous goal of creating all manner of spacecraft before NASA came along offering contracts. So SpaceX built it’s own workforce, worked out its own development processes, put its own skin in the game by building its own spacecraft before signing contracts from customers like NASA, tested to learn and not testing to pass and so on. So this is why SpaceX spacecraft will now return Boeing’s stranded crew back to Earth.
• Organizations hunting for money are destroyed by organizations that have found their purpose. General Motors famously developed an electric vehicle ages ago, until it was killed off because it wasn’t making money straight away. If General Motors was able to go back in time … it would almost certainly reconsider! If they had maintained their electric vehicle program they would potentially be a market leader today (which they are not … they are just a ‘player’) noting that groups of countries are starting to only allow electric vehicles on the road.
• So what do you do? Does your organization only judge success based on immediate returns? Meaning that everyone is hunting profits by week? This means there is no long-term vision which means you meander your way to obsolescence. It is those companies that stick with their long-term vision through highs and lows. Amazon took decades to create a meaningful profit … but it is kind of a big deal now!

The Trouble with Habits

Abstract

Chris and Fred discuss the issues we often have with ‘habits.’ Habits can be good for us. But ‘bad habits’ are just that. Ever heard the excuse ‘but that’s the way we have always done it?’

Key Points

Join Chris and Fred as they discuss how ‘habits’ dominate our lives … both for better for worse. So what does this mean?

Topics include:

• Decisions are about CONFIDENCE.  You can be ‘confident’ to make the right decision because you fundamentally know and understand all aspects of a problem, and know what will remedy it. Another form of ‘confidence’ occurs when you look for standards or procedures to comply with … which usually only happens when you don’t know and understand all aspects of a problem. You can get ‘confidence’ from having what appears to be a water-tight legal contract. You can also get ‘confidence’ from simply doing what has always been done.
• So not all CONFIDENCE is equal. And it comes down to culture. If you are a leader, and want to look for someone to blame when something goes wrong, then you are creating an organization that is based on ‘confidence’ from doing what has always been done. So no one risks anything. Nothing changes. You slowly drift toward mediocrity, and then to irrelevance.
• The best form of CONFIDENCE is the stuff you get from KNOWLEDGE. Which again comes down to leadership. If people make the right decision based on seeking information on hand and using it, AND you reward that decision even if the outcome is not optimal or desirable … great! This means you become an organization that fails fast, and fails your way to the top. You are actively pushing the boundaries of your organization’s knowledge by having this mindset. And this is what you tend to see in true industry leaders. So what organization is yours?
• But don’t get LAZY. If you used Highly Accelerated Life Testing (HALT) for a component last year to great effect … that doesn’t mean that this is the right thing for all components moving forward.

Show Notes

There is a general uneasiness with AI with some in industry, but it can be hard to really get to the root of why. Dianna and Fred discuss what they’ve been hearing from others.

• There’s an unease about authenticity.
  • AI challenges the idea that humans are unique in thought and creativity in art, writing, and more.
  • There is an increase practice of listing “this will be done by humans” in services and products (things like resumes, technical papers, and more).
  • AI is forcing a restructuring of how professionals structure fees, from time-based to result-based.
• Integration of AI is becoming commonplace.
  • The integration of AI in so many daily tools are now competing with each other.
  • The interfaces of AI with other logic tools – what are the failure points?
  • Using AI can complicate what should really be simple. Just because we can doesn’t mean it adds value.
• AI is available, or is it?
  • There is a huge computational cost for using AI.
  • Most are not really knowing what to use AI for and how. We’re still figuring it out.
  • All knowledge is not available. Trade secrets are limiting databases.
• How can we approach AI right now for tomorrow?

Reliability and Vacations

Abstract

Chris and Fred discuss reliability engineering … and vacations/holidays! … how are we going to make this topic relevant …

Key Points

Join Chris and Fred as they discuss how vacations, holidays, and breaks in general can be really beneficial to what you do. And it’s not just about balance.

Topics include:

• Go for a walk. Engineers, designers and technicians often get tied into the mindset of not finishing the job until it is finished. But the problem with this is that if you don’t allow yourself breaks, then your efficiency and productivity goes down. Especially when it comes to software coding. Just going for a routine walk allows your brain to reset, and you will get the job done faster as a result!
• OK … but still not sold on this ‘new age’ lazy approach to work. Really? How many times have you spent furiously solving the wrong problem? Einstein famously said that if he had one hour to save the world he would spend fifty-five minutes defining the problem and only five minutes finding the solution. But this is something many engineers, designers, technicians and maintainers forget. They are so not-used to taking breaks that they feel like they need to be doing something all the time. And taking the time to define (or perhaps ponder) the problem feels like a break.
• Focus on the DECISION. And one of the best ways of working out what the right decision you need to inform is often happens when you take a break. Once you are furiously exerting effort, there is no time to think about whether or not the effort you expend is actually helpful. So take a break!

Doing Calculations

Abstract

Chris and Fred discuss how to calculate ‘confidence’ and other things regarding probability and statistics … particularly as it applies to reliability!

Key Points

Join Chris and Fred as they discuss how we go about calculating things like the ‘confidence’ in the outputs … that other equations give us! Wow. What are we talking about here?

Topics include:

• Equations give us numbers. Like the reliability estimate of a product at two years based on a combination of test and field data. And there are some issues here. With like to think that these equations we find in textbooks are objective. But … there are equations based on different approaches. So they aren’t objective (such as regression on ‘x’ versus Maximum Likelihood Estimate – MLE). Both those horrible terms in the brackets are different approaches to fitting the ‘line of best fit.’ So you need to choose the approach you like … making everything subjective.
• Confidence is (an emotion) that is a measure of you. But we often talk about it as if it is an objective number. So you might use one of the two approaches in the point above … but how ‘confident’ are you that the output from one approach is correct versus the other? If the data we are trying to fit that line to is from a random process, there will always be some uncertainty (lack of confidence). Some software packages give ‘confidence intervals’ … like the 90 % confidence region that the true line lies. But how does this work?
• So what do you need to do? Understand. If you are just wanting a number so you can move on … you are not the listener we are after. Otherwise, take the time to understand where the calculation comes from, what competing approaches there are, and what might go wrong. But most of all, you need to understand the decision you are trying to make.
• And if you understand the decision … then you might not need a lot of ‘confidence’ in some of your outputs to make the right decision. Or you might not need to use calculate anything at all!

Key Points

Join Carl and Fred as they discuss how to set the right pace for teaching or facilitating teams.
Topics include:

• Whether you are facilitating a team, sharing information one-on-one, presenting to a group, or teaching a class, there are principles for conveying knowledge.
• What are the key elements for being effective when conveying knowledge?
• The pace of teaching is important.
• Rather teach less content, and be effective in conveying knowledge.
• Too fast and students or team members cannot keep up.
• Too slow and the team loses interest.
• Your pace should assume you allow and encourage lots of interactivity with audience.
• The purpose is not to get through the slides or the material, it is to successfully convey knowledge.
• What percent of total teaching or presenting time is telling, versus what percent of time is questions, interactions, and exercises? Consider 40% tell, and 60% interaction, questions, discussion, exercises.
• How does learning occur?
• What is role of making mistakes in learning?
• The pace of teaching or presenting has to have time for discussion, and interaction.
• Practice new material so that the pace is right.
• Be flexible so you can take the time that is needed to ensure fundamentals are understood.
