Elementary, Mr. Watson: APEX EXPO—The Ghosts of Past, Present, and Future

On the eve of APEX EXPO 2026, the Anaheim Convention Center in California rests in a rare and fragile quiet. The lights are dimmed, the escalators are still, and the long corridors echo with only the distant sounds of crews finishing their work. In the corner of a long hallway, an engineer sits alone, wondering why he’s even there. “I have too much work to get done,” he thinks, as he looks down at the large stack of active projects—schematics marked with revisions and standards, and notebooks filled with hurried notes and half-finished thoughts—spread across his lap and at his feet.

Elementary, Mr. Watson: Why You Can’t Afford to Miss APEX EXPO 2026

APEX EXPO is one of those rare events where the whole industry comes together in one place: design, fabrication, assembly, materials, reliability, equipment, and standards. It’s where some of the most respected voices in the industry take the stage: researchers, practitioners, and thought leaders who are shaping what comes next. Between the technical sessions and keynote presentations, attendees are gaining insight directly from the people driving innovation and setting direction across the electronics ecosystem.

Elementary Mr. Watson: Where the PCB Ends and Advanced Packaging Begins

Change sits at the center of almost everything in PCB design. From the earliest days of printed circuits to today’s highly integrated electronic systems, stability does not define this discipline; evolution does. Materials change, component geometries shrink, signal speeds increase, and manufacturing processes advance. With each shift, we reshape the role of the PCB designer, sometimes quietly, and other times in a way that feels like a freight train driving through your living room.

Elementary, Mr. Watson: Design Intent Over Design Speed

I was recently asked a simple but powerful question: Is there anything available to PCB designers today that would be truly advantageous to them that they’re essentially not using? My answer was yes. However, it reminded me of an experience before Christmas one year when I was killing time at the mall. I had wandered into an Apple Store to look around, and I overheard a customer say, “Yeah, I just need a phone.”

Elementary, Mr. Watson: Finding Balance on the Seesaw and in Life

One of my greatest joys as a grandfather to nine (soon to be 10) grandkids is spending time with them at the park. It doesn't take long before I find myself wedged halfway down a slide that was never designed for someone my size, or sitting on a seesaw where my weight instantly teaches a real-time physics lesson—mainly that Grandpa is not as light as he feels inside, and yes, gravity loves me more.

Elementary, Mr. Watson: Why Traces Alone Won’t Save You

Whether you call them polygons, pours, planes, floods, copper areas, copper regions, zones, or copper shapes, they all refer to the same fundamental concept: large, defined areas of copper used to control electrical performance, thermal behavior, and manufacturability on a PCB. In a recent Design-007 column, we looked at how we ended up with this endless list of names describing the same basic thing. Somewhere along the way, the industry decided that one name simply wasn’t enough, so we created half a dozen synonyms that confuse newcomers and occasionally amuse veterans.

Elementary, Mr. Watson: The Four Horsemen of Copper Confusion

If there were a PCB Design Dictionary of Confusing Terms, the cover would feature four words that have baffled generations of engineers: polygons, pours, planes, and floods—or what I refer to as the four horsemen of copper confusion. They sound simple, as if they belong in a geometry textbook or a weather report, but in PCB design, they overlap, develop, and sound interchangeable until you realize they aren't.

Elementary, Mr. Watson: Heat—The Hidden Villain of Power Electronics

If electricity were a group of college students, then power electronics and the PCB designers who dive into it would insist on driving the car on every road trip because they know the car inside and out—they’re the students with jumper cables in the trunk, a tire pressure gauge in the glove box, and snacks stashed under the seat. While the others argue over playlists and directions, power electronics is busy ensuring the alternator doesn’t fry, the headlights don’t dim, and everyone reaches the destination with fuel still in the tank.

Elementary, Mr. Watson: High Power: When Physics Becomes Real

Have you ever noticed how high-speed design and signal integrity classes are always packed to standing room only, but just down the hall, the session on power electronics has plenty of empty chairs? It's not just a coincidence; it's a trend I've observed over the years as both an attendee and instructor.

Elementary Mr. Watson: Chasing Checkmarks, Not Signal Integrity

For the September 2025 issue of Design007 Magazine on signal integrity, I explored how the PCB is similar to a military obstacle course: walls that sap energy like impedance mismatches, barbed wire that cuts like crosstalk, and mud pits that drag a signal down like attenuation. The takeaway was clear that a PCB is not a flat drawing; it's an electromagnetic ecosystem filled with hazards that test every signal that dares to cross it. The real danger lies not in the obstacles themselves, but in the fact that many designers never see them.

Elementary Mr. Watson: Running the Signal Gauntlet

If you’ve ever run a military obstacle course, you know it’s less “fun fitness challenge” and more “how can we inflict as much pain in the shortest time possible?” You start fresh—chest out, lungs full of confidence, thinking you might even look good doing this—and 10 seconds later, you’re questioning all your life choices.

Elementary Mr. Watson: Routing Hunger Games—May the Traces Be Ever in Your Favor

I’d like to share a harsh truth, and I say this as a friend: PCB designers are often their own worst enemy. It’s rarely the complexity of the circuit, the last-minute changes from mechanical, the limited enclosure space, or the ever-expanding list of design rules that send projects to the dust heap of failed boards. More often, it's our own decisions, made too quickly and narrowly, and with too little foresight, that sabotage an otherwise good design.

Elementary, Mr. Watson: Why Your PCB Looks Like a Studio Apartment

In November 2022, I wrote a column called "Is Your Bathroom in the Kitchen?" This piece related a bizarre real estate listing that emerged out of St. Louis that had architects scratching their heads and interior designers cringing. Nestled in the historic Central West End sat a 200-square-foot apartment that completely defied logic. It wasn't the size that raised eyebrows, it was the layout. Here's the kicker: While that's rare in real estate, it's shockingly common in PCB design.

Elementary Mr. Watson: Closing the Gap Between Design and Manufacturing

Modern PCB designers are not merely engineers or technicians. I believe that PCB design, at its core, is an art form, and modern PCB designers should be considered artists. Beyond the technical calculations and engineering rules lies a creative process that involves vision, balance, and a passion for what we do. Like any artist who works with brush and canvas or chisel and stone, a PCB designer shapes invisible pathways that bring ideas to life. Each trace, layer, and component placement reflects thoughtful decisions that blend form, fit, and function.

Elementary, Mr. Watson: Rein in Your Design Constraints

I remember the long hours spent at the light table, carefully laying down black tape to shape each trace, cutting and aligning pads with surgical precision on sheets of Mylar. I often went home with nicks on my fingers from the X-Acto knives and bits of tape all over me. It was as much an art form as it was an engineering task—tactile and methodical, requiring the patience of a sculptor. A lot has changed in PCB design over the years.

Elementary Mr. Watson: Retro Routers vs. Modern Boards—The Silent Struggle on Your Screen

There's a story about a young woman preparing a holiday ham. Before putting it in the pan, she cuts off the ends. When asked why, she shrugs and says, "That's how my mom always did it." She asks her mother, who gives the same answer. Eventually, the question reaches Grandma, who laughs and says, "Oh, I only cut the ends off because my pan was too small." This story is a powerful analogy for how many PCB designers approach routing today.

Elementary, Mr. Watson: PCB Routing: The Art—and Science—of Connection

Many people who design circuit boards love the routing part of the design. This is partially because we want to stop looking at the annoying rat's nest of connections, which seem to have no rhyme or reason at first glance. We want to get to something more exciting. Routing is the ultimate part of solving the puzzle. You take all the messy lines from the schematic and turn them into neat, organized paths.

Elementary, Mr. Watson: Design Data Packages—Circle of Concern or Circle of Influence?

I've often been asked, "Can you have a perfect PCB design?" At first blush, it seems like the answer should be yes. After all, if you follow all the rules, double-check your work, and use the right tools, it should be perfect. Right?

Elementary Mr. Watson: Navigating RF—A Glide Path Approach to Design Success

On a flight, I can always tell when we begin our descent because that subtle drop in my stomach tells me the altitude has changed. Landing an airplane involves a gradual, precise process called the glide path. It descends at the correct speed and 3-degree angle to touch down smoothly and safely on the runway without bouncing or coming to a sudden stop. Pilots use specialized tools like the Instrument Landing System (ILS) or GPS to stay on the correct path. Lights on the ground, called PAPI lights, help pilots know if they are too high or too low.

Elementary Mr. Watson: Ensuring a Smooth Handoff From PCB Design to Fabrication

At the 2020 Tokyo Summer Olympics, the U.S. men's 4x100-meter relay team had high hopes of winning a medal. The team comprised some of the fastest sprinters in the world, but something went wrong. In a relay, four runners must smoothly pass their baton to the next runner inside a zone on the track. If a runner drops the baton or it’s passed outside the zone, the team risks disqualification. The U.S. team’s pass between the second and third runner was messy, slowing them down. By the time the last runner received the baton, the team had lost too much time. They finished sixth in their heat and didn’t qualify for the final.

Elementary, Mr. Watson From Classroom to Career—Bridging the Gap in PCB Design Talent

Has anyone else felt we're doing more with less in our industry and we constantly need more and better talent? Although we are in the middle of what I consider the golden age of the PCB industry in terms of innovation, we still don’t have the necessary talent to fill positions. We need to take a serious look at our industry, figure out how we found ourselves in this position, and what we can do to turn the situation around.

Elementary Mr. Watson: The Road Ahead—Advances in PCB Design Technology

This year introduces a new generational group, likely to be dubbed Generation Beta, since Generation Alpha was born between 2010 and 2024 and is considered the first generation born in the 21st century. Generation Alpha grew up in a world dominated by smartphones, artificial intelligence, and rapid technological advancements. It is anticipated that Generation Beta will live to see the 22nd century.

Elementary Mr. Watson: How to Reinvent Your Professional Journey

The end of the year is the perfect time to reflect and embrace the significance of this moment. This season is not simply a milestone marking the end of one chapter and the beginning of another; it’s an opportunity to acknowledge our journey and appreciate the lessons we’ve learned, the challenges we’ve overcome, and the people who have supported us.

Elementary, Mr. Watson: Rules of Thumb—Guidelines vs. Principles for PCB Design

The infamous "rules of thumb" are simple guidelines that help you make decisions based on experience, not exact facts. They’re like shortcuts we use because they work most of the time. For example, if you want to know if spaghetti is done cooking, a common rule of thumb is to grab a spaghetti strand and throw it against the wall to see if it sticks. I used to do that, except that instead of the wall, I used the ceiling, which drove my mother crazy.

Elementary, Mr. Watson A Designer's Dilemma—Metric or Imperial Units?

In the early 1800s, as trains began to spread across the United States, different companies built their tracks in ways that made sense to them. They chose their track widths (gauges) with no set standard. Some tracks were about four feet wide, with others at five or even six feet. Each company thought their choice was best, but this led to a big problem: Trains from one track couldn't run on another if the gauges didn't match. Often, trains had to stop at the state line for all their goods and passengers to switch trains, which cost extra time and money.

Elementary, Mr. Watson: The Gooey Centers of Hybrid PCB Designs

Anyone who knows me knows that I have a special relationship with food. Taking a twist on the words of Will Rogers, "I never met a buffet I didn't like." A balanced diet, to me, means having cupcakes in both hands. One of my favorite foods is cheeseburgers. One of my colleagues at Palomar College recently invited me out for a meal, and we ended up in a burger place in San Diego. I wanted to go the conventional and safe route: a double-patty cheeseburger. My friend insisted that I try the restaurant’s special: a peanut butter cheeseburger. “Really?” I told him. “What an interesting combination.” But he insisted I try it, and since I consider myself an adventurous person, I gave it a go.

Elementary, Mr. Watson: The Paradigm Shift of Silicon-to-System Design

Imagine you were asked to build a city. What approach would you take? In the old way, city planners designed each building independently. They focused on making each building strong, aesthetically pleasing, and valuable. But they didn't always consider how all the buildings would fit together in the city. Roads, power lines, and parks were added later, sometimes making the city confusing or complicated to get around.

Elementary, Mr. Watson: Debunking Misconceptions in PCB Design

PCB design can be likened to the poem, “The Blind Man and the Elephant” by John Godfrey Saxe. In the poem, six blind men of Indostan “to learning much inclined,” went to see the elephant “that each by observation, might satisfy the mind.” The first man fell against the elephant and concluded it was like touching a wall. The second man felt the elephant’s tusk and exclaimed, "It is very like a spear." The third blind man, feeling the vast and squirming trunk, decided it was a snake. The fourth man felt the elephant's leg and said the elephant “is very like a tree." The fifth man touched the massive ears and decided an elephant is very like a fan. Finally, the sixth blind man, feeling the elephant’s swinging tail, proudly proclaimed, "I see, the elephant is very like a rope."

Elementary, Mr. Watson: Mechatronics—The Swiss Army Knife of Engineering

Many folks in my age group raised on a farm always carried a pocket knife. My choice was a Swiss Army Knife. It was a versatile, multi-functional pocketknife manufactured by Victorinox and Wenger and is renowned for its compact design. What was nice about the Swiss Army Knife was the array of tools that fold out from its handles. Whatever job you need to accomplish, the Swiss Army knife can handle it.

Elementary, Mr. Watson: Cultivating a Culture of Collaboration

About three years ago, I wrote a column, “PCB Design—It's a Team Sport,” which discussed the importance of collaboration and working as a team. At that time, we were under restrictions due to the COVID pandemic and were coming to grips with our new roles and struggles as PCB designers. I opened my column by stating, "Our entire industry had to reinvent how we did things. It's during the difficult times the most valuable lessons are learned." While 2021 seems like another lifetime ago, those lessons still linger.

Elementary, Mr. Watson: Pushing Design Boundaries

Overconstraint: What a concept. Our first thoughts would be: What are we hurting by overconstraining a design? Isn't it better to be safe than sorry? What is meant by overconstraint? It means to apply excessive constraints. In engineering and mathematics, it's used when there are too many simultaneous equations to result in an exact solution. For example, fitting a line to many points is overconstrained because a line cannot be drawn simultaneously through all of the points. In PCB design, overconstraints always occur, including dimensional, electrical, manufacturing, and timing constraints. The list goes on.

Elementary, Mr. Watson: Ensuring Design Integrity

Back in February, many of us watched the "Big Game." It reminded me of the saying, “It's not how you start that is important, but rather how you finish." It is perfectly okay when you are talking about sports, you get off to a bad first half and need to recover in the second half. However, when it comes to PCB design, this is not a good practice. If things start badly, they usually don't recover. They continue down that same path, costing more money and losing design time.

Elementary, Mr. Watson: Know the Tradeoffs With Embedded Designs

One of my great joys as a grandfather of eight is spending time with them at the park. It doesn't take too long until I'm getting stuck on a slide that is too small for me or on the seesaw, with me on one side and them trying to lift me. At that point, they learn some harsh lessons in physics and how heavy Grandpa really is. A seesaw is a relatively simple device, but it’s a great way to explain a rather complex concept in PCB design: design tradeoffs. Each decision made throughout a design comes with inherent pros and cons.

Elementary, Mr. Watson: Consider Physics When Designing Non-traditional Geometries

Electronics have profoundly impacted society, shaping how we live, communicate, work, and entertain ourselves. Nearly every aspect of our lives is affected by electronics in some way. If you want proof, sit and watch people in public; everyone is on a screen. The communication revolution alone has transformed our lives, enabling instant global connectivity. Some would argue these advances come with their distinct disadvantages.

Elementary, Mr. Watson: William of Ockham Meets Printed Circuit Boards

William of Ockham was a significant figure in medieval philosophy who lived from 1285 to 1347 and was an English Franciscan friar, philosopher, and theologian. William of Ockham is most famously known for formulating the principle of Occam's Razor, also known as the principle of parsimony. In simple terms, Occam's Razor is a problem-solving rule suggesting that when you have multiple possible explanations, the simplest one is usually the best. The most straightforward solution that fits all the facts without adding extra assumptions or complications.

Elementary, Mr. Watson: IPC Standards, A Love Story

In the fall of 1998, I was a novice in the printed circuit board design field, beginning a two-semester course at a community college in San Marcos, California. Although I was shifting my career from an electronic technician to a PCB designer, I sat nervously as the class started, and the instructor began handing out several paperback-bound books that looked more like a pamphlet on steroids. Those “textbooks” were my introduction to IPC standards. Unbeknownst to me, those basic standards became my reference for every design I would do moving forward.

Elementary, Mr. Watson: Flex Designs—The Future and Beyond

Electronics are continually evolving, driven by innovations in printed circuit board technology. Flexible PCBs have emerged as a revolutionary force, reshaping the PCB industry and influencing the design and functionality of countless electronic devices. Some believe that flexible PCBs are a relatively newer technology, but as we will see, that is not true. Since I’m an instructor, here’s a short history lesson on how we got here and what we can expect.

Elementary, Mr. Watson: Circuit Simulation, SPICE, and AI

According to the Federal Aviation Administration’s flight time limitations and rest requirements, a commercial pilot is restricted to 36 flight hours in a week, 100 hours in 28 days, and 1,000 hours in any calendar year. But before these pilots even start flying the friendly skies, they spend considerable time in a flight simulator. In the same way, PCB design and circuit simulations provide the same advantages: a controlled, safe environment for testing a circuit without the considerable overhead of fabricating and assembling the PCB.

Elementary, Mr. Watson: Honey, I Shrunk the PCBs

As an industry, we live in our own version of “Honey, I Shrunk the Kids.” PCB designs are shrinking smaller and smaller with each design spin. Our industry demands the latest and greatest, where innovations coming off the line must be smaller and sleeker and have all the latest new functions, which, as we know, determines the fit and form. Miniaturization and integration are growing trends with electronics.

Elementary, Mr. Watson: Where Have All the PCB Designers Gone?

What are the biggest challenges in PCB design? Now, that’s a loaded question, but one that I’d like to talk about. Before I do so, I think it’s helpful to talk about challenges themselves, how we view them, how they affect us, and what we do about them. What one person perceives as a challenge may not be a challenge for another person. Challenges can vary based on individual circumstances, goals, values, and strengths or weaknesses. Some folks avoid challenges or never expect to have issues, but this is entirely unrealistic.

Elementary, Mr. Watson: Slash Sheets a ‘Smorgasbord’ of Materials

Slash sheets touch on materials, one of my favorite areas of PCB design, and what I refer to as “the buffet of the PCB world.” After all, this smorgasbord of materials comes in an endless variety, with differing balances of reinforcement and resin, from different manufacturers and vendors, and from a variety of sources. Add the possibility of out-of-date or deteriorated panels, and it makes ensuring the quality of your next PCB design a real hit or miss.

Elementary, Mr. Watson: Responsible PCB Design Must Go Beyond RoHS

In the field of PCB design, a massive paradox exists. No doubt, the PCB industry is a fascinating field. The ever-changing design environment faces constant and more complex challenges to make products smaller, faster, and cheaper. There are endless ways that electronic innovation changes lives for the better, as seen when advanced medical systems provide patients a new lease on life. But there also is a downside, an unfortunate side, to PCB design, and it has bothered me for some time. There is a massive amount of new PCB products hitting the market, especially in the consumer marketplace. But what happens to the "obsolete" products that are discarded, known as e-waste? This dark side of the PCB industry is not spoken about in social circles, but with innovation comes some negative.

Elementary, Mr. Watson: If Not You, Then Who?

I have had the opportunity to do a considerable amount of traveling. Over many visits to the Philippines, I noticed a distinct lack of nursing homes, and learned that it is a common practice for children to take care of their parents. They even have a designated term for this practice, ma alaga, roughly translated as "take care of." This practice leads to some fantastic outcomes in the culture, resulting in each age group taking care of its own, with a beautiful overlapping of different generations. What a great concept.

Elementary, Mr. Watson: Turning Your Career up to Eleven

In the 1984 classic rock documentary “This Is Spinal Tap,” guitarist Nigel Tufnel proudly demonstrates an amplifier whose volume knobs are marked from zero to 11 instead of the typical zero to 10. From that movie, we get the phrase, “Turn it up to 11.” It’s a lesson of seeing a limit and exceeding it. So, here’s a rather personal question: What is your level 11? You are the only person who can answer that question, and I hope you will, both in your personal life and in your career.

Elementary, Mr. Watson: Designing For a Higher Purpose

John Watson asks the question to PCB designers: Why do you do what you do? It's a question someone asked him recently and the answer was clear. In this column, John shares a personal journey of a friend whose life was changed in an instant because of the efforts of so many, including a PCB designer. This story should give us all pause to consider the magnitude of what we do. The "puzzle pieces" of a PCB design become a working model for consumer products that affect even our most basic senses. Read on to learn more about the "why" behind his passion for PCB design.

Elementary, Mr. Watson: The Art of the PCB

After finishing the statue of David, Michelangelo—Italian sculptor, painter, architect, and poet of the High Renaissance—was asked how he had created such a beautiful work of art. He said, “The sculpture was already complete within the marble block before I started my work. I merely had to chisel away the superfluous material.” After decades of being in the industry and seeing countless designs, it’s still amazing to me to see the exceptional beauty of a well-done PCB design. For designers, each PCB begins as a blank canvas; not knowing what the final product will look like, we walk a fine line between engineering and artistry, often producing fascinating results.

Elementary, Mr. Watson: Is Your Bathroom in the Kitchen?

Several years ago, a report came out of St. Louis of a strange apartment on the market. It was in the community of Central West End. With a small floor plan of only 200 square feet, the entire bathroom was placed right in the middle of the kitchen. Well, that's interesting. It gives new meaning to the studio apartment. With closer examination, there were several convenient features available, so here's my point: In this story are some fantastic lessons for us as PCB designers. In real estate, it's pretty uncommon to find the bathroom in the kitchen; but metaphorically speaking, it's done all the time in a PCB design (ouch).

Elementary, Mr. Watson: Is the Tail Wagging the Dog?

I recently had the opportunity to work on a rather critical PCB design project during what should have been the final design review. Unfortunately, after presenting my well-organized PowerPoint presentation, I asked the most challenging question to the group of assembled engineers and managers, “So, what do you think?” As we went around the room, nearly every comment started with something like, "You know what we could do..." Ideas flew around the room, fueling a full-blown brainstorm. Unfortunately, what followed could best be described as organized chaos. The result was that several of the suggestions took the product back to re-design, and what was supposed to be the final steps didn't happen.

Elementary, Mr. Watson: Anatomy of Your Component—Footprint, Part 2

Have you ever gone to a buffet hungry and looking forward to digging in? You grab the plate and start down the food line, picking things as you go. Halfway through, your plate is stacked up with food, looking very similar to the Leaning Tower of Pisa. Then you get to the good stuff at the end of the buffet, but there’s no room on your plate. At this point, you probably feel much like that with the first part of looking at our footprint, but rest assured, although your plate is already full, the good stuff is still waiting for us. I have saved the best for our second offering.

Elementary, Mr. Watson: The Anatomy of Your Component—Footprint

I hate to disappoint you if you expect to get everything about footprints from this modest column, but a short search online results in a long list of technical standards and books on this subject. So, I will only hit the surface of the discussion. I have often spoken about the parent-child relationship principle in PCB design. In this series, we have learned that we can see how that "relationship" is supported directly by the information in the component itself. As a short review, the parent-child relationship is where you use an input of data, material, or parts (parents) as the foundation or resource for another item or document (child).

Elementary, Mr. Watson: The Anatomy of Your PCB Component, Part 2

In the start of my series of the anatomy of a component, I discussed that the component has two major divisions. The first is information that consists of name, description, parametric information, sourcing (part choices), and the datasheet (Figure 1). Next, the component comprises symbol, PCB footprint, 3D model, and simulation models. I gave the example of the dissection of the frog, with an analogy that every part has a purpose. In the same way, each part of our component has a distinct purpose in our PCB design, including our models.

Elementary, Mr. Watson: The Anatomy of Your PCB Component, Part 1

One of the classes I dreaded the most in school each year was biology. This was because I knew it was only a matter of time before I would face the rite of passage for most high school students: dissecting a frog. It wasn’t something I ever looked forward to. We had to go through the same educational exercise and maybe with the same apprehension for most of us. But my point in bringing up the painful experiences of our high school years is, although it was difficult, I did learn a powerful lesson: Every part has a purpose.

March 10, 2022

Elementary, Mr. Watson: The Five Pillars of Your Library, Part 3—Architecture

Before I continue with the series of the five pillars of your library, I want to do a little review. Although every library is different, the five pillars are consistent with any sound library. You place these pillars to support a specific building section in building construction. To pull one out requires the remaining ones to hold the total weight above. So, each of these supports is needed for your library to succeed. You cannot choose which of them you intend to follow; to pull just one out results in the toppling of the others.

Elementary, Mr. Watson: The Five Pillars of Your Library, Part 2—Managed

The 1972 classic movie “The Candidate” tells the story of Bill McKay (played by Robert Redford), who was running for the state senate. Although he was a long shot and an underdog, McKay ends up surprising everyone with an incredibly close win. After the concession speech of his opponent, a vast mob surrounds McKay. He fights through the crowd, trying to reach his campaign manager Marvin (played by Peter Boyle). Finally reaching him, McKay pulls Marvin aside into a hotel room, sits on the bed, and after several seconds of silence, finally asks a very intense question “So, what do we do now?” The campaign manager looks bewildered, so McKay asks the question again, “What do we do now?”

Elementary, Mr. Watson: PCB Data Management and Security

As a grandfather of six grandchildren, one of my great joys is spending time with them. There is nothing better than spending an afternoon at the park and especially playing on the teeter-totter. It's all fun and games until grandpa gets on one side, and they try to lift me. Then the harsh reality and a teachable moment in leverage, balance, and just how heavy grandpa really is hits pretty hard.

Elementary, Mr. Watson: We’ve Never Done It That Way Before

The September edition of Design007 Magazine discussed the theme of collaborating and working with a team. In that issue, I wrote a feature article called “PCB Design Is a Team Sport.” After that edition was published, I had several follow-up questions and conversations with individuals; they agreed on the importance of teamwork but felt that it's easier said than done. It's challenging because of the inherent problem of team members accepting or handling change very well. Change it's a word that sends shivers down the spine of some. You know those sort of individuals. They're easy to identify. The ones that constantly remind everyone, "We never did it that way before." As if how we did things in the past was so much better.

Elementary, Mr. Watson: The Danger of Rogue Libraries

For PCB designers, the most common part of the library is the collection of components used in the PCB design process. But, I have seen some libraries have other information, including a resource area, a group of documents, standards, and articles. So basically it can have anything you want.

Elementary, Mr. Watson: Managing Risk in PCB Design

PCB design is like bungee jumping. With the complexity of a PCB design, the intricate details, and various steps, it's rather easy to make mistakes. Those mistakes, many times, do not show up until it's too late and the board has gone off to fabrication and assembly. By the way, a good rule is not to use your assembly house as your quality control team for PCB designs.

Elementary, Mr. Watson: Paying the Price To Be a PCB Designer

Today, the electronics industry is flourishing with innovations and technologies. The result is that the “good” designers are left in the dust. Truthfully, our industry doesn't need more good designers; rather, we need great designers—those who can face any challenge and instead of cowering in the corner, looks at the task at hand and says, "Bring it on."

Elementary, Mr. Watson: Demystifying Bypass Capacitors

As PCB designers, we work under the simple rule of cause and effect, and a PCB design can quickly become a petri dish for the butterfly effect to flourish. One of those areas that can quickly snowball into major problems is your PCB power distribution structure. When it goes wrong, it usually goes very wrong and has significant issues throughout your design.

Elementary, Mr. Watson: What You Need to Know About a PCB Design Career

Never stop learning. Why? Because the industry never stops changing. Those that continuously stay in that state of learning are the ones who succeed. The old saying “Knowledge is power,” often attributed to Sir Francis Bacon, has never been truer. Fortunately, there is never a lack of things to learn. Don’t ever become apathetic about learning. Make a point of keeping a running list of ideas or subjects that you want to research, and then purposely set aside time in your week strictly to study and learn about these things anywhere you can.
