All About Flex: FAQs on RoHS for Flex Circuits
In 2003, the European Union (EU) adopted a standard called the Restriction of Hazardous Substances (RoHS), which restricts the use of certain materials in electronic products and electronic equipment. The intent is to reduce the environmental impact of known hazardous materials and has driven changes in manufacturing processes and materials used to manufacture a wide array of electronic products.
People in the printed circuit and electronic packaging industries often ask me about re-shoring. My response generally is that re-shoring is a myth. It seems that whenever I try to contact someone by email I get an automated response stating, "I am currently in China and will return to my office on…" Many of the facilities and much of the equipment that would be needed to re-shore have been auctioned off or sent to the scrap heap.
Happy’s Essential Skills: CIM and Automation Planning, Part 1
There is a lot of talk and information about automation, but I find that there is very little available on automation planning. This is one of my specialties. I started by getting a master's in EE in control theory. This went well with my B.S. in chemical engineering as I specialized in process control and IC manufacturing.
The European Space Agency on Reliability
Stan Heltzel is a materials engineer working for the European Space Agency, and he is tasked with the job of procuring and qualifying PCBs that end up in satellites. I met with Stan at EIPC’s Summer Conference to discuss his presentation on qualifying a fabricator, his role at the ESA, and updating of space standards.
Lightning Speed Laminates: Smaller Circuits--Material Properties and Thermal Issues
Coefficient of thermal expansion (CTE) is typically considered for PCB reliability, but it can also have an impact on circuit performance for applications exposed to varying temperatures. Due to CTE, a circuit will change physical dimensions when the temperature changes. If the circuit has small features or tightly coupled features, the physical change of the circuit dimensions can cause a shift in electrical performance.
Standard of Excellence: Communication Breeds Success
We all need to talk to one another. You need to work closely with your customers. And we all need to work with the new generation of PCB designers and design engineers, many of whom have never set foot in a board shop.

At the recent Nadcap meeting in London, I spoke with Eltek USA President Jim Barry about the state of the company, further investment from their new owner, and their focus on the U.S. market.
All About Flex: Soldering Flexible Circuits
The most common methods for component attachment on flexible circuits and rigid printed circuit boards involve soldering. The basic principles for soldering are the same for both flex and hard board, but soldering components to flexible circuits involves certain specific considerations vs. our rigid cousins.
Brooks' Bits: Your Traces Have Hot Spots!
The reasons for the temperature variation at high temperatures are not too hard to understand. There may be minor contamination under the trace or in the copper that accounts for it. Certainly, at higher temperatures (say above about 300°C) the board may begin to delaminate, severely disrupting its cooling characteristics. There may be small variations in trace width or thickness that help account for the delam, and these effects would be randomly distributed along the length of the trace.
Happy’s Essential Skills: Quality Functional Deployment (QFD)
Wikipedia has one of the best definitions of quality function deployment (QFD): “QFD is a method to help transform customer needs (the voice of the customer or VOC) into engineering characteristics (and appropriate test methods) for a product or service. It helps create operational definitions of the requirements, which may be vague when first expressed. It prioritizes each product or service characteristic while simultaneously setting development targets for the product or service.”

Happy’s Essential Skills: Roadmapping Essentials
Many industries recognize value and benefits in technical roadmapping. However, misuse leads to abundant dangers and can render a technology roadmap useless, or worse. Good roadmaps embrace uncertainty, exploiting apparent weakness to derive maximum insight and understanding. The Technology Roadmapping Handbook from the University of Leipzig is a useful roadmapping reference.
Trouble in Your Tank: Building Reliability into the PCB, Part 2
In Part 1 of this column on reliability, I presented the common PTH failures encountered when reliability is less than robust. PTH reliability is influenced by several factors including the quality of the PTH after drilling, plating thickness and plating distribution in the PTH. In this column, I will present additional factors, including the Coffin-Manson model in the context of understanding reliability failures.
Catching up with Artnet Pro’s Meir Polack
Interested in all aspects of our industry, I have lately been especially focused on our suppliers, because more and more of my board shop clients are concerned about their vendor support chain as more of them are either reducing their presence in North America or leaving altogether. I am also keenly interested in companies whose mission it is to help the PCB industry survive, especially a company that does not abandon the “little guys,” but rather is focused on helping those smaller companies to compete with the giants whose goal is to run them over.
Let’s Talk Testing: Welcome Your Product to the Real World!
The days, weeks, and (sometimes) years that go into a product’s development usually are incomprehensible to the lay person. Like laws and sausages, no one wants to really understand what has gone on behind the scenes to make your “thing” a reality. They just care that your widget makes their life easier and/or more enjoyable!

There, between hiking and gardening, we found time to discuss Pete’s rich history in the PCB industry and the many changes and surprises he’s seen in the manufacturing process over the years.
The Gerber Guide, Chapters 15 and 16
Before sending your Gerber files off to your fabricator, you are often advised to check them using a reputable Gerber viewer such as GC-Prevue. This is excellent advice. Note that this involves more than just verifying that the viewer displays your intended image: It is important that you check too that the file is valid.
Shane Whiteside and Summit Interconnect: Aspiring to New Heights
A few weeks ago I was privileged to meet with Shane Whiteside in Anaheim, California, at KCA Electronics. Whiteside, former COO of TTM, has helped launch a new company—Summit Interconnect— which encompasses the recent acquisition of KCA Electronics and Marcel Electronics International. Once again assuming an executive role, this time as CEO and president, Whiteside shared his story, strategy and vision for this new chapter.
All About Flex: Considerations for Impedance Control in Flexible Circuits

All About Flex: Creating Via Holes in Flexible Laminates
Almost all double-sided and multilayer flexible circuits require through-holes or vias to enable an electrical connection between conductive layers. Creating a reliable plated via requires several critical steps. The first one is creating the through-hole.
Inside Spirit Circuits
I was recently treated to a factory tour with Spirit Circuits’ Managing Director Martin Randall, to learn more about their process line and how it has evolved over time. In the discussion following, I learned about Spirit’s involvement in the China market and how they’ve structured their business to handle quick turn prototypes locally and high volume abroad.
High-Throw Electroless Copper– New Opportunities for IC Substrates and HDI Manufacturing
The one constant in electronics manufacturing is change. Moore’s Law, which successfully predicted a rate of change at which transistor counts doubled on integrated circuits (ICs) at lower cost for decades, is ceding to be an appropriate prediction tool.
Happy’s Essential Skills: Project/Program Management
No matter what your job, you may have to manage, or play an active role in, a project at some point during your career. It takes a great deal of skill to do this well, but the time you invest in building good project management skills can pay off enormously.
Using the Type 1 Gauge Study to Assess Measurement Capability
Measurement capability is a critical aspect of ensuring product quality, therefore a measurement system must be assessed before being used on products. Understanding how to assess measurement capability becomes critical. The Type 1 Gauge study is typically the first step in a measurement system analysis program. Type 1 Gauge parameters are explained, and a worked example using electroless nickel immersion gold (ENIG) is provided.
A Thermal Conductivity Measurement Method, Adapted to Composite Materials Used in the PCB Industry
Most of today’s printed circuit board base materials are anisotropic and it is not possible to use a simple method to measure thermal conductivity along the different axes, especially when a good accuracy is expected. Few base material suppliers’ datasheets show X, Y and Z thermal conductivities. In most cases, a single value is given, moreover determined with a generic methodology, and not necessarily adapted to the reality of glass-reinforced composites with a strong anisotropy.
