What makes a great design?
It depends.
We talk about the spectrum of designs (from great to spam), the various customers engineers need to design for, and how engineers can work with their team toward defining what a great design should be.

We worked on a project with our team and met our goal!
Except, management isn’t happy – they expected something else.
Seeing if we have alignment on goals is easy if we gather the team and stakeholders for 10 minutes and use a continuum.
There are certain categories that goals will fall within. A continuum is a way we can list those categories, get alignment, and gain an understanding of how ‘big’ of a project this is going to be. We get clarity on our goals.
Is it hard? Not at all. Is it eye-opening? Sometimes. It can help us move forward with a discussion to help ensure we’re all successful.

The reliability performance of a product or system exists because the decisions that occur during the creation of the product establish how well an item will survive without failure. The choice of material, finish, or technologies, along with all the other decisions involved, define how well a product performs, including its reliability. [Read more…]

Like most manufacturers, the electronic manufacturing industry relies on countless suppliers to fulfill its manufacturing needs. I’m quite certain there is no one within the EMS space who fabricates their own boards using materials produced in house, operates their own semiconductor foundries, designs and manufacturers their own components, and produces soldering materials for their reflow process. Our industry relies on a vast network of manufacturers throughout the world to build even the simplest electronic assembly.
Intellectual property security, cyber security, national security, are all hot topics today. No one wants their hard-earned intellectual property stolen. This is most true within The US military establishment. There are, at present, numerous policies, procedures, and regulations designed to protect various parts of our supply chain from unscrupulous people and companies.
Today, companies are concerned about “controlled unclassified information” (CUI) and “controlled technical information” (CTI). That brings us to IPC-1791. What is IPC-1791? My guest today, IPC’s Randy Cherry will explain.
Randy is Director of Validation Services at IPC. Validation Services is a series of certification programs that qualify products and processes to the IPC industry standards.
Once companies have completed their certification they are listed as an IPC Trusted Supplier on the IPC Validation Services website.
Randy has over 30 years experience in Engineering with Printed Circuit Board and Backplane fabs, High-Speed Pressfit Backplane Connectors, and SMT (Surface Mount Technology) Assembly practices. He is a certified SMT Process Engineer and an IPC Auditor, and, he’s my guest today on this episode.

Chris and Fred discuss the difference between ‘confidence,’ ‘tolerance’ and ‘prediction’ intervals. Is there any point in understanding the difference between these concepts? … or is it something only statisticians find useful?

Relationships matter! And they can be difficult to understand.
We’re taking relationships between variables. Does one variable affect another? Or do they just correlate? Understanding which matters to the values of our decisions.
We talk about the saying “Correlation does not imply causation”, how to find a confounding variable, and ways to check that we’ve got the triggering cause that’s going to affect our outcome.

Kirk and Fred discussing and reflecting on some of the spooky reliability problems we have seen (or not seen) that sometimes have haunted us on this Halloween 2022 episode of SOR

Meetings to ADD productivity to our day? Yes!
We need our time to be productive, individually.
We also need input from our team. We can use meetings to add productivity to our day, if done right.
We break it down: hours in a day, limits of humans, and the minimum requirements of a good meeting.

Whether new to reliability or a veteran, you have probably heard about the Weibull distribution. It has almost mythical status amongst those who conduct reliability data analysis … or in other words – turning a jumble of dots (data points) into information that actually means something. So why do we ‘worship’ the Weibull distribution? What is so special about it? Whether you have been doing this for a long time or five minutes, you will get something out of this webinar that looks at one of the most popular tools for reliability analysis.
