Designing Electronics to be Reliable in Harsh Environments

The challenging world of electronics becomes even more challenging when the end product is destined for harsh environments. For high reliability products operating in a harsh environment, the quest for reliability is not just a goal—it’s an imperative. These are not your everyday gadgets; often they’re critical components of systems designed to operate under extreme conditions, where failure is not an option. From the scorching heat of desert landscapes to the unyielding cold of arctic tundras, from the high-pressure depths of our oceans to the radiation-filled expanse of space, the demands on these electronic products are as varied as the environments themselves.

While ocean depths, outer space, and frozen tundras are arguably harsh environments, we don’t have to look too far for examples of product failures in less harsh environments. One example that comes to mind is the state of public EV charging stations. Government reports have concluded that up to 25% of public EV chargers are at any given time.

While there are many reasons for this, one may conclude they are not designed and manufactured for the intended in climactic operating environment.

On this episode, we’ll uncover the numerous challenges that designers and engineers face in their quest for reliability, durability, and functionality of the final product.

As we navigate through this complex landscape, we’ll highlight the strategies that enable these products to not just survive, but excel in unforgiving conditions.

A Conversation with Indium’s Rick Short about Education-Based Marketing

We’re the best, we’re number one, we’re better than them, we’ve won more awards than our competitors, we’ve all seen those ads. While this form of advertising isn’t unique, when’s the last time it caused you to buy a product based on the ad. I think we all know that answer.

There was a time when we relied heavily on print advertising to determine what products were available and from whom. The two primary methods to gain product awareness were print advertising and trade shows. While advertising and trade shows still exist, they are no longer the primary method of product awareness.

31 years ago, beginning on April 30, 1993, all of that began to change. What happened on April 30, 1993? Public access to the Internet was born.

Over the past 31 years, Internet technology propelled us into an age of self discovery. The older generation accuses the younger generation of always having their face in a screen. While that may be true, it’s not always TikTok, Instagram, Facebook, or Snapchat. People today, particularly younger people, research products, technologies, and a host of other things online. Consumers today are far more educated on the products they wish to purchase them at any time in history.

In what I find to be an exceptional irony, much of the industry responsible for building the technology behind Internet connectivity continues to advertise their products in a pre-Internet style.

You may ask, what does this have to do with reliability? Building reliable products requires a net sum of a vast amount of best practices. One of those practices is insuring the right products, procedures, specifications, designs, and so many other factors are implemented.

This goal cannot be accomplished by just reading advertisements from sellers. Frequently, engineers struggle to solve problems without a complete knowledge of the root cause of the problem. Particularly today, with so many in-house subject matter experts retiring, advertisements boasting the number of customers, time and business, and where they place in the hierarchy of competitive products do not assist the engineer and understanding the root cause of a potential problem, and certainly not the solution.

Over the past several years, several companies in our industry have begun to change their advertising strategies from transactional, to transformational. That is to say they help to connect problems to solutions, more than merely hyping products.

My guest today fully understands the value and effectiveness of what I like to call “Conscious Marketing “.

A Candid Conversation with Industry Icon Doug Pauls

We’ve discussed the silver tsunami on the show numerous times, the unprecedented rate of which employees are retiring. When engineers and other employees retire from companies, they take with them more than a set of gold cufflinks or an engraved plaque. In many cases, they also take with them wisdom and knowledge.

Perhaps this is never more true than in the case of my guest today. And who is that? My friend and colleague Doug Pauls.

Component Tape Splicing Best Practices with Larry (The Professor) Welk

Optimization has become an important goal within the electronic assembly industry. While modern electronic assembly techniques utilize a variety of equipment, one specific type of equipment often consumes a disproportionate percentage of the overall equipment budget, that is the place machine. The cost of the machine, associated conveyors and feeders, require that the machine is running as often as possible.

The airline Industry refers to this as “wheels up” time. Airlines make money when the aircraft is in the air “wheels up”. On the other hand, anytime the wheels are down, the aircraft is not making money for the airline.

I listened to an interview a few years ago with the CEO of Southwest Airlines, a US discount carrier. Unlike most other airlines, Southwest does not charge its customers to check bags. The CEO was asked by the reporter why they have not joined the rest of the industry in charging for checked bags. The CEOs answer was genius. If Southwest Airlines began charging for check bags, it would actually slow down the boarding process as more and more passengers would drag their bags onto the aircraft most likely resulting in a number of those bags having to be checked at the gate.

Southwest Airlines is famous for having the fastest aircraft gate turns in the industry, frequently under 30 minutes. Yes Southwest airlines charged for checked baggage, it would require more time at the gate before the next flight would be ready to depart. That would result in fewer flight segments per aircraft per day. In other words, allowing customers to check bags for free equates to more “wheels up” time and, subsequently, more profit for the airline.

The same principal can apply to pick and place machines. When Pick and machines are running product, they are making presumably making money. When they sit idle, they are arguably costing money. What can assemblers do to improve the optimization or “wheels up” time on their pick and place machines?

My guest today, Larry Welk believes he has an answer. Larry Welk, a.k.a. Professor spice is the co-owner of Smart Splice, a manufacturer of tape splicing tools.

Larry will review tape splicing best practices and explain how tape splicing, when performed correctly, can lead to higher pick and place machine optimization.

So, buckle your seatbelt this podcast episode is officially wheels up!

Circuit Board Design and Acquisition Best Practices

This episode is a little different from our usual episodes. First of all, it’s a dual-branded episode. It’s both a Reliability Matters Podcast and an Ecosystem podcast episode. The Ecosystem podcast host Judy Warner will join me for an unusual topic, at least for The Reliability Matters Podcast.
Most of my audience are assemblers of circuit assemblies. Our world begins with a bare board. I reminded of the biblical passage “the Wiseman built his house upon the rock”. Circuit boards are the foundation from which we build our products upon.

There’s so much that goes into the design and fabrication of a bare circuit board. Who designs these boards, what criteria were they given, what materials did they choose, where are they made, how much do they cost, and, perhaps most importantly in our world, how easy are they to assemble?
To help answer these and so many other questions, Judy and I have assembled an expert panel of board designers.

Our expert panel consists of Gerry Partida, Vice President of Technology at Summit Interconnect and Julie Ellis, Field applications engineering manager for TTM Technologies.

Environmentally Responsible Alternatives to Traditional PCB Fabrication

Today, we delve into an increasingly critical aspect of technology and electronics manufacturing – the pursuit of environmentally responsible electronics manufacturing. Our industry has witnessed many environmental revolutions.

The elimination of popular cleaning solvents brought on by the Montreal protocol in 1989, soon followed by strict VOC regulations pertaining to cleaning chemicals.

The switch from lead-based solders to lead free alloys, led by the Restriction of Hazardous Substances directive, known as RoHS implemented within the EU in 2003 and adopted nearly worldwide, regulations regarding the disposal of electronic waste (e-waste) resulting in many countries mandating regulations and programs for the safe recycling and disposal of electronic products, and more.

These regulations and others have inspired some companies to seek eco-friendly alternatives to traditional Printed Circuit Board (PCB) fabrication.

The combination of numerous environmental regulations has resulted in many companies’ implementation of sustainability programs.

As our world becomes more connected, the demand for electronic devices continues to rise, and with it, the importance of mitigating the environmental impact of their production.

Novel Wireless / Wearable ESD Monitoring

We are all aware of the damage electrostatic discharge can wreak on components and electronic products. We mitigate ESD damage through various forms of monitoring. We wear wrist and heel straps, stand on ESD-safe flooring, utilize ESD work stations, and more. We even have ESD testing locations that will test a human standing on a specialized testing station. But what happens the moment that person steps off the tester?

My guests today are Dr. Daan Stevenson and Dr. Jonathan Tapson of IONA Tech, a manufacturer of a novel wearable ESD monitoring device that provides constant real time ESD monitoring.

Normally, I don’t talk about specific products on the show. We usually limit our conversations to best practices. This is a little bit of an exception to my normal rule. From time to time, a product is introduced that is so novel, it’s worthy of a conversation. And that’s the case here.

Dr. Daan Stevenson is the Chief Executive Officer of IONA Tech. Daan has a background in mechanical and aerospace engineering. During his doctoral research, he studied the high voltage charging of spacecraft, which are electrical capacitors in the same way that the human body is.

A Conversation with Industry Icon Bob Willis

We are all aware of the supply chain issues our industry has faced. Beginning with electronic components, it has spread to so many other types of parts are industry relies on. Fortunately, it looks like we are beginning to come out the other end of the supply chain shortage.

But the supply chain problems have further spread to the labor market. If you are in a position to hire people for your company, you know firsthand how difficult that process can be today.

Adding to the level of labor acquisition difficulties is the great “Silver Tsunami”, otherwise known as the great retirement.

As I mentioned on our last episode, episode number 130, the fact is, baby boomers are entering retirement in greater numbers. According to government data, from now until 2030, 10,000 Baby Boomers each day will hit retirement age. Millions will begin to officially retire.

Some of these retirees are designated subject matter experts within their companies. Not only are people retiring, they are taking with them a vault of valuable knowledge.

This has created an even larger demand for consultants within our industry. I’ve had several industry consultants on my show over the last few years, including today’s guest.

And who is today’s Guest? Legendary industry consultant, Bob Willis. If you’ve been in this industry longer than 18 seconds, there’s a good chance you’ve at least heard his name. If you’ve been in this industry for virtually any length of time, there’s a good chance you’ve seen his videos, read his books, or watched him present at numerous industry conferences and symposiums. If I reviewed Bob’s complete professional biography, it would take an entire episode. Here’s my conversation with my friend and colleague, Bob Willis.

During our conversation, we discussed Bob’s newest book, “Robotic Soldering Inspection and Defect Guide”.

Anyone who makes a donation to Bob’s chosen charity will receive a download of his book as well as access to Bob’s complete book collection:
