Where’d Design East Go?

As recently as February, United Business Media staff were promoting the then-upcoming Design East trade show.

Big changes and improvements were promised, and given last year’s flat turnout and buzz, they would have been a welcome shot in the arm.

We saw “would have been” because the show has been canceled, with the understated  message on the website telling visitors only, “Thank you for visiting the Design East site. Unfortunately, Design East will not be held in 2013.”

The fact is, it’s really tough to do a great show in certain markets. Even Boston, which has a thriving tech community, doesn’t go out of its way to support these events. Show producers wrestle with the question over whether it makes sense to undertake the expense, effort and risk involved, especially when it might cannibalize other convention offerings.

As an event organizer that has put on shows in the Boston area in the past, we can empathize with UBM’s decision. But we also understand the fragile nature of supplier loyalty, and when you open the door for customers to go somewhere else for their needs, they usually walk through it.

Printing Money

Per a new report from IDTechEx, printed electronics are expected to really take off … some day.

The latest data from the research firm targets an attractive 15.3% CAGR over the next decade, mostly driven by OLEDs. That will push the overall market from just north of $16 billion today to $76.8 billion in 2023, IDTechEx says.

But what I found interesting was the market for conductive inks (see the table below). This is an area that is, in my opinion, the Holy Grail for electronics. Get it right, and we will solve all sorts of design, weight, cost and manufacturability issues.PE-Forecasts-Table1

The Value of Open Source

There were a number of interesting sessions and debates at the DesignWest show. One of the more passion filled, was on the value of Open Source hardware. Some people think it will save the world,if only everyone will do everything open source. Some people think it’s a stupid waste of time without a real business model.

Personally, I see more value in it than either of those extremes. What I see is that open source hardware (and software) has lowered the barriers to entry for people who want to create, design, build and sell. Yes, big companies innovate, but a vast amount of innovation and employment comes from small companies that start out without anything more than ideas.

A decade ago, before open source hardware became well know, it was pretty difficult and expensive to start a hardware company. In fact, I recall quite a few predictions and discussions about the death of hardware as an industry in the country. Open source hardware has lowered the barriers to entry and raised the level of awareness of hardware to the point that now, in my opinion, the environment is as ripe for start-up companies and innovation as was the late 1970s and 1980s.

Open source hardware has given us that, and that will be far more positive economically than whether an specific business can find a way to make money with open source hardware. These new businesses may or may not sell open source hardware. Again, that’s far less important than the fact that open source hardware has really enabled so many more people to create.

What are the Conflict Minerals?

Currently, the U.S. Securities and Exchange Commission (SEC) list of conflict minerals consists of four named minerals. They are tantalum, tin, tungsten (referred to as the three T’s) and — no surprise here — gold, which somehow came into being with the potential for conflict hidden deep in its very molecular structure, it seems.

Here, let’s take a look at the four conflict minerals in more detail.

Tantalum. Columbite-tantalite (often called coltan in Africa) is the metal ore from which the element tantalum is extracted. Tantalum is used in making capacitors, particularly for high performance applications with a compact size and high reliability, ranging from hearing aids and pacemakers to airbags, GPS and ignition systems, vehicle anti-lock brake systems to laptops, mobile phones, video game consoles, video cameras and digital cameras. In its carbide form, tantalum is very hard and resistant to wear and corrosion. This makes it ideal for jet engine turbine blades, drill bits, end mills and similar “heavy duty” tools.

Tin.  Cassiterite is the chief ore needed to produce tin. Tin is ubiquitous in our culture, seems we can never have enough. It’s light and durable. Perfect for cans. Used a lot in solder on electronic circuit boards — in other words it’s used in all electronic equipment. Tin is also commonly used in biocides, fungicides and as tetrabutyl tin/tetraoctyl tin, an intermediate in polyvinyl chloride (PVC) and high performance paint manufacturing.

Tungsten.  Wolframite is a key source of tungsten. Tungsten is a very dense metal element. Because it’s dense and heavy it’s used to make things like fishing weights, dart tips and golf club heads. Like tantalum carbide, tungsten carbide possesses hardness and wear resistance properties and is frequently used in applications like metalworking tools, drill bits and milling. Smaller amounts are used to substitute lead in so-called “green ammunition”. Minimal amounts are used in electronic devices, for example, in the vibration mechanism of cell phones.

Gold. Gold is of course used in jewelry, electronics, and dental products. It is also present in some chemical compounds used in certain semiconductor manufacturing processes.

These minerals are sometimes referred to as “the 3T’s and gold”, 3TG, or simply the “3T’s.”

Europe is currently looking at taking conflict mineral action. And, under the US Conflict Minerals Law, additional minerals may be added to the current list in the future.

Believing Foxconn Means Suspending Belief

The Foxconn makeover is in full swing, with the latest this piece from the New York Times that supposes that the world’s largest ODM is worried that Apple — yes, Apple — might be bringing it down.

When Apple was subsequently criticized for low wages and poor working conditions at his factories in China, it was Mr. Gou’s company, the Foxconn Technology Group, and not Apple, that caught the most heat.

What this conveniently ignores, of course, is that no matter how demanding and dictatorial Steve Jobs could be, those weren’t Apple employees jumping to their deaths from their Cupertino offices.

Such unpleasantries aside, what the story also reveals is that Foxconn does not intend to go head to head with its customers. There’s ample evidence to the contrary already, of course, not the least of which are the Foxconn retail stores popping up all over China, not to mention the litany of ODM phones and other consumer electronics it design and makes.

To paraphrase an old saw, believe what I say, not what I do.

All Quiet on the Wilsonville Front

A timely piece from the hometown paper of Mentor Graphics looks at how Carl Icahn has calmed down now that Mentor’s stock price has doubled since he started accumulating shares of the company a couple years ago.

The legendary investor is Mentor’s largest shareholder, at just under 15% of the company. Since he starting buying up shares, Icahn has been vocal about the need for the software company to shed its country club culture. He forced the issue in 2011, successfully getting three of his nominees elected to the company’s board. Last year, Mentor only nominated one of the three, which drew fire from Icahn, but with the stock price up 50% over the past 12 months, all is quiet in Wilsonville.

‘Innovate or Die’

While not directly related to printed circuit boards, this piece from Time Magazine on the Japan’s Uniqlo shows how one entrepreneur had the vision and courage to cast off decades of cultural aversion to risk to build one of the largest clothing companies in the world.

Founder Tadashi Yanai, now 64, took over his parent’s small-town clothing business and, realizing it would end up in bankruptcy without change, remade the entire company.

“Innovate or die,” Yanai reminds us. It’s a lesson that’s absolutely true in PCBs as well.

Another National Treasure Lost?

The April 26 news in the Cedar Rapids Gazette announcing the impending closure of Rockwell Collins’ 49-year-old printed circuit operations should be spotlighted nationally for several reasons. It cites declining profits and business as the reason for the decision. It follows by just 6 months the layoff by Rockwell Collins of 300 workers. It signals the continued decline of manufacturing in America along with the accompanying know-how and innovation formerly ascribed to Collins’ printed circuit business. It says that outsourcing PCB production is fairly common in the electronics industry. This is true. But then, the article states that Apple, the “most valuable company in the United States outsources the manufacture of all its components, including printed circuits.” What it does not tell us is that these components are also primarily purchased and assembled into iPhones and iPads in China, mostly by Foxonn (Hon Hai). Tens of thousands of Chinese workers are employed to do this profitably for Apple.  Is the Rockwell Collins spokesperson who was quoted inferring that Collins’ boards are to also be made in China? Is there an ITAR issue involved in this case? In any event, the announced closure plan should remind us that our once strong manufacturing base that produced nearly 60% of the jobs in the US when the Collins PWB works was founded has now shrunk to about 20%, or less. Manufacturing in America is now reported to be only about 20% of our GDP. So I listen to all those that say we must bring jobs back to America and wonder, “How? Over what period of time? In what industries?”

Nepcon China, held in Shanghai April 23-25, was busy, but with tire-kickers, not buyers. The show, slightly smaller than the previous edition, seemed to lack the excitement of previous years as business outlook was cloudy. Several former Chinese companies appear to have dropped out now that show producer Reed is applying uniform prices to all exhibitors. Chinese firms had paid reduced fees for spaces in prior years.

There was little in the way of innovation. There was a plethora of Western reporters from virtually all of the related media. There were at least 3 well known industry journalists from the U.S. and Europe conducting video interviews in English as well as Chinese of exhibitors and celebrity attendees.

Concern over the economic effect caused by the Chinese-Japanese territorial tiff over the Senkaku/Diaoyu islands increased during the show as stories of customs delays in critical spare parts and new equipment shipments were reported. Japan is a major suppliers of SMT assembly and test equipment to our industry in China.

Dr. Philip Carmichael, the new IPC president of China operations, was there meeting people, making presentations, negotiating collaborative deals for the future, and giving interviews. During his short tenure Dr. Carmichael has met every major organization in our industry in China to see how he can increase the value proposition of IPC members. Making sense of 23 different trade shows and major events can be daunting, but Carmichael seemed unfazed by the challenge. He has already increased IPC’s China membership by about 20% this year. He advised us to watch for new announcements in the near future.   The IPC sponsored hand soldering competition remained a crowd-pleaser in Shanghai as it was at its other previous venues.

CTEX 2013, which started as a show in Suzhou named “Circuitex” by Taiwan board makers, will have its 9th presentation May 8-10 at the Suzhou International Exhibition Center. The name “Circuitex” was first coined by MacDermid in the early 1960s when it established its first specialty chemical line of products for the printed circuit industry. This year’s presentation will cover bare boards, SMT and ICs with a focus on products for the iPhone5, IPad Mini, and Nexus 7 by Apple and Google. The event is being promoted as the 9th Suzhou PCB/SMT Show.

Measuring Void Content

A reader writes: Dear Dr. Ron, I need to measure the void content of an alloy. Is there an easy way to do it?

After a little thought, it occurred to me that the densities of the voided and unvoided material will likely hold the answer. I derived the result below. Assuming we know the density of the unvoided material, we can measure the density of the voided material with the Wet Gold Technique, discussed in recent posts, if the voids are not connected (closed cell.)  If the voids are connected (open cell), you could machine the foam to the shape of a rectangular parallelepiped and determine the density of the foam as the mass divided by the volume.

As an example, let’s say you have a closed cell aluminum foam. We use the wet gold technique to measure its density at 1.5g/cc. The density of solid Al is 2.7g/cc.

So the volume fraction of voids is:

Sadly, this technique could not be used to find void content in solder joints, or in BTC (e.g., QFN) thermal pad connections (which are so handily mitigated by using solder preforms.)  The derivation for the above equation follows:

 

Best Wishes,

Dr. Ron
