Happy’s Essential Skills: Project/Product Life Cycle
The product, and or project (process) life cycle (PLC) is fundamental to a corporation intent on developing new products or processes. It sometimes is called the new product introduction (NPI) process but that is only half of the life cycle. There is product support, enhancement and eventually, obsolescence.
The Sum of All Parts: Planning for a First-Time-Right PCB Design
The development of highly integrated and high-speed, chip-based circuit boards brings several functional benefits. But at the same time, these can introduce additional challenges to the actual board itself. Therefore, developing an effective plan for designing, developing, testing and producing the final PCBs is a good business practice.
All About Flex: Flexible Circuits and Kaizen Events
All Flex uses a variety of different tools and techniques in its continuous improvement efforts. A Kaizen event or Blitz is one technique that has resulted in significant improvements in our yields, productivity and customer satisfaction.
Working With Circuit Design Engineers
Until the late 1980s, many PC board designers were converted technicians, mechanical designers, and artists who learned to read a schematic and mastered artwork taping. The EEs would often share their opinions, but you could listen to them or ignore them and the circuit would likely function either way. This era created some tension between designers and their EE counterparts, because they completely ignored each other’s ideas.
A Conversation with Walt Custer: Market Report
In a recent conversation, Walt Custer shared current market data and industry trends, detailing those market segments and regions that are currently seeing growth and those that are in decline. Walt also offered his interpretation of the data, which he uses to forecast the upcoming month.

Design Strategies for Success—and Profit
In today’s economic environment, making money on a project is getting more and more challenging. Those years when businesses like mine were practically printing money are long gone. If you are under 30 years old, you probably do not have this point of reference; it’s been one downturn after another for your entire adult life. But for us older folks, times were really good back then. So, what happened? You happened, as well as a million others like you. In other words, the market is a little cramped now and much more competitive, which dilutes our profit per project.
Sunstone Circuits R&D: 3D Printing Great for Prototyping
We’ve been hearing a lot about 3D printing for the past few years. But where does 3D printing fit in with traditional rigid circuit board development? Sunstone Circuits recently completed a project that focused on that very question. Sunstone Product Manager Nolan Johnson explains why 3D printing is a viable option when it comes to jigs and parts of the support infrastructure that are needed when prototyping today’s emerging technologies.
Getting a Handle on Handling Errors
When gathering info for this month’s topic on handling strategies, I knew there was much happening in the automation end of things and all that it can do for handling. But I also knew it was not something that is easy for the “little guy” to do—automation is expensive, in general, and it is not always conducive to the high mix of small lot sizes typical of the many prototypeplus facilities in North America and Europe.
Stepping up to Laser Processing for Flex, Part 3: Readiness and Site Preparation
With so many processes to keep track of in a flex manufacturing line, it can be easy to get lost in the details and begin to rely on your suppliers to address any issues that might crop up. However, given that laser processing equipment and flex materials are both impacted by your facilities, your attention to and investment in clean, stable, and robust facilities and support equipment will quickly pay off in less downtime, higher yield, and—perhaps most importantly—fewer headaches!
Brooks' Bits: How Many Vias Does It Take To…?
During 2015, I enjoyed a very productive collaboration with Dr. Johannes Adam, from Leimen, Germany. This resulted in several papers, but one in particular is relevant for this column, “Via Currents and Temperatures.” In that paper, we used a simulation tool, thermal risk management, developed by Dr. Adam, to simulate current flowing through a via and then determine the temperature of the via. Read on to find out how our results contradicted conventional wisdom.
Happy’s Essential Skills: Technical Writing
Technical writing is one of those topics that they don’t really talk about in college—at least not where I went. Writing and English has never been a strong like of mine compared to science and math. So I did my required time in English and wrote my lab reports the best I knew how.
Beyond FR-4: High-Performance Materials for Advanced Designs, Part 1
In the past 40-plus years of PCB manufacturing, the primary material of choice has overwhelmingly been e-glass supported FR-4 resin laminates. This is due to the excellent dimensional stability and reasonably acceptable thermal performance (based on glass transition temperature [Tg] and decomposition temperature [Td]). In general, these materials exhibit impressive performance and excellent cost for a wide range of applications.
Beyond Design: The Need for Speed—Strategies for Design Efficiency
Years of experience with one EDA tool obviously develops efficiency, whether the tool be high-end feature-packed or basic entry-level. And one becomes accustomed to the intricacies of all the good and bad features of their PCB design tool. However, there comes a time when one should really consider a change for the better to incorporate the latest methodologies. This month, I will look at productivity issues that impede the PCB design process.

This month, Vern Solberg focuses on outline planning, physical reinforcement, and accommodating bends and folds in flexible and rigid-flex circuits.
Made in Brazil: Focusing on What Matters Most!
Every company claims to be constantly improving their business or process, but not as many grasp the core idea of continuous improvement and live it daily. This is evident when one analyzes companies competing on the same market, providing quite the same products, yet having totally different results. Improvement is often misunderstood as doing things differently, which is a huge mistake.

Happy’s Essential Skills: Using Web Resources
The World Wide Web is a real boon to information retrieval. The key is getting to relevant information and not being overwhelmed by the sheer number of references. When confronted with a process problem, the urgency of a solution requires that you know how to use Web resources expeditiously.
The Four New Agreements to Explode Profitability
We have been brainwashed to focus on a relatively small number of metrics such as revenue and profits as the driving force behind critical outputs of our organizations. The actual driver of these critical metrics is the mostly informal systems in which the company operates. Because in excess of 90% of the profitability of a company is systems-based, a sustainable increase in profitability requires changes (optimization or re-creation) in existing systems.
Flex Talk: PCB Sourcing? One Size Does Not Fit All
When analyzing a set of PCBs to improve yields and maximize profits, the first place to start is with a critical review of each PCB design. Are there any attributes that are pushing your manufacturer’s standard design rules? If so, is this necessary to the design or is there another approach that could improve the manufacturer’s yields, reduce cost, and ultimately increase profit?
