No capacity for capacitors: How world issues impact product development and supplier selection
I have recently been talking to people in small and mid-size businesses about their goals for this year and the challenges they face. New product development is on many companies’ list of goals, but blocking it—the supply of parts. I expected to hear about delays from suppliers or contract manufacturers (CMs) who reduced capacity during the downturn and are now trying to balance their hiring efforts with returning business. (And I did hear some of those stories.) What surprised me was not that part supply was delaying products, but that the decreased supply is often caused not only by problems like the worldwide economic crisis, but also by global issues like political turmoil in Africa.
I heard about product launches being delayed because of a capacitor—specifically a tantalum capacitor. Tantalum capacitors are common in high-tech devices because of their high reliability, small package size and high maximum operating temperatures. Prices and lead times for these parts are increasing because of a drop in the availability of the element tantalum.
The 2008 closing of an Australian tantalum mine, which contributed more than a third of world tantalum production, was a major cause of that decrease. Those facilities shut down when the market price for tantalum was too low and mining the material was no longer profitable. Although this has happened before, and prices are high enough now that Australian production is expected to restart soon, in the meantime manufacturers are left with a difficult choice.
Tantalum mines are also located in Africa, in a part of Congo that has been politically unstable for a long time. At a minimum, the supply of tantalum from this region is unreliable due to war. Worse, to get raw tantalum from Congo, capacitor companies must do business with brutal militias who do horrible things to women, children and each other.
Minerals like tantalum are being called “conflict minerals” and being compared to the “blood diamonds” mined in other parts of the continent. In a recent blog post and New York Times op-ed piece Nicholas Kristof calls for companies making electronic gadgets to demand that their capacitor manufacturers not only state that they use conflict-free materials, but also provide proof of it. Groups like Run for Congo Women and the Enough Project (with its Raise Hope for Congo campaign) are working to raise awareness about this issue through efforts like this Mac vs. PC video spoof that suggests an unsettling similarity between the two types of computers:
Awareness of the Congolese conflict minerals has reached Washington, D.C. An amendment to the financial reform bill currently in front of Congress calls for companies to disclose any materials in their products that originated in Congo or adjoining countries. If that bill gets signed into law, it will surely help. But will it be enough?
And what about other minerals and other regions? A recently published study shows that war-torn Afghanistan is rich in elements important for manufacturing, including lithium, a primary component for new battery technologies. How will this discovery impact Afghanistan? Tantalum and other key elements for electronics manufacturing could have helped improve the life and living conditions of the Congolese people instead of continuing to promote and perpetuate war. Can the elements found in Afghanistan be used to help bring stability and wealth to the region and not cause further violence?
As end users start demanding conflict-free contents in their devices, manufacturers will want to think hard about the choices they make as they design and source their next product.
How to ensure clean water in Ghana: Build filters locally

According to UNICEF, in Ghana 25% of deaths in children under 5 are caused by diarrhea. In Northern Ghana, where more than half the population gets its water from wells, ponds and streams, this percentage is even higher. These water sources often contain disease-causing microorganisms because they’re too remote for centralized filtration and sanitation systems to reach.
Susan Murcott and Pure Home Water, the non-profit that she co-founded, are working on creating and distributing affordable ceramic filters in this region. The product has been well-received, but the organization is planning to go one step further: PHW is planning to build a factory to make the filters locally. Currently the organization buys filters from a factory 12 hours away. With its own local factory PHW will be able to drop the filters’ cost from $16 to $10. Since the filter will still cost more than most Northern Ghanaians can afford, PHW intends to use the factory to also make profitable ceramic products, like bricks, that can subsidize the water filters.

In addition to cost reductions, PHW will gain tighter control over the design and quality of the filters and the manufacturing process. The PHW team has some MIT engineering and Sloan School of Management interns working with them to conduct product research, run consumer studies and test the unusual manufacturing process, which uses combustible materials like rice husks to create small voids that allow water to pass but trap bacteria and parasites. Murcott learned the technique for making the ceramic from the non-profit organization Potters for Peace in Nicaragua.
You can learn more about PHW’s ceramic manufacturing process, product research and business plan in an article on the MIT News website.
A story in every surface – Vetrazzo countertops
Anyone connected to the construction industry has been hit hard by the economy in the past few years. And now, unless a company is part of the green revolution, the construction industry is going to rebound without it. Vetrazzo recycled glass and concrete countertops are a green product—that’s what led me to select one for my recent kitchen remodel (a simple 2-3 week project that ended up taking more than 2 months after I broke a water pipe, but that’s another story…). The company’s manufacturing process and unique supply chain show that it’s a company with a different approach.
Vetrazzo, the name of both the company and the product, was invented in 1996 in Berkeley, California, by a glass scientist working on his PhD, who had a passion for the environment. He had the idea of adding recycled glass to a concrete-like material to create a new type of building supply. Demand for the product grew quickly from small, handmade batches for the local building community to an installation at the Ritz-Carlton South Beach in Miami Beach, Florida.
In 2006, armed with a new management team and some venture capital, Vetrazzo opened its doors in a brand-new state-of-the-art manufacturing facility in Richmond, California.
To manufacture the countertops, Vetrazzo combines recycled glass with cement, additives and pigments, pours the mixture into a flat tray and with its patented technology, vibrates the tray to spread glass evenly throughout the cement. The slab is then baked, hand-polished and examined by eye for any flaws that need mending before it’s ready for sale.
All of the glass used in Vetrazzo is recycled, and it makes up about 85% of the total material. Most of the glass comes from curbside recycling programs. Other glass comes from windows, dinnerware, stemware, windshields, stained glass, laboratory glass, reclaimed glass from building demolition, traffic lights and other unusual sources. Every Vetrazzo surface has its own history. We track that history, and after you purchase and register Vetrazzo, we provide a Certificate of Transformation that tells you where the glass in your Vetrazzo came from.
Some color choices are offered all the time because the materials come from a readily available supply. Other colors, like Firehouse Red and Traffic-Light Red, are limited editions only available when a collection of the appropriate glass can be acquired—anything from a manufacturing defect to a demolition project could provide it. One reason for the demise of Traffic-Light Red, for example, is that the source traffic lights are now made of plastic instead of glass.
While I find the company’s manufacturing batch process and unique supply chain cool, what makes Vetrazzo interesting to me is the company’s internal drive for sustainability. They practice what they preach. They are reutilizing an old Ford plant that uses existing daylight, has a ‘negative-pressure dust booth’ to minimize air pollution, and has a system to recycle water. In the company’s blog, Message in a Bottle, you can read about Vetrazzo’s victory garden, as well as its 4-Legged Waste Diversion Program (aka – Mama Goat).
Vetrazzo’s green process and philosophy has the company well-poised for the future. I recommend visiting its website to see samples of all the different stones and read about the colorful glass that’s in each one.
AMT & AMTDA report first quarter manufacturing technology consumption up 33.7%
The American Machine Tool Distributors’ Association (AMTDA) and the Association for Manufacturing Technology (AMT) report that March U.S. manufacturing technology consumption (USMTC) totaled $258 million. According to the AMT website:
This total, as reported by companies participating in the USMTC program, was up 58.1% from February and up 49.5% from the total of $172.59 million reported for March 2009. With a year-to-date total of $548.53 million, 2010 is up 33.7% compared with 2009.
The USMTC report provides regional and national U.S. consumption data of domestic and imported machine tools and related equipment. It’s considered a leading economic indicator, as investments in capital metalworking equipment are generally made for the purpose of increasing capacity and improving productivity.
More details can be found on the AMT website.
In an instant, Polaroid film is back: The Impossible Project
Thanks to The Impossible Project, Polaroid film is back, and production of Polaroid cameras is following.
In the 1960s, half the homes in America had a Polaroid camera. By the year 2000, 13 million of them had been sold. Then, in 2007, the financially struggling company ceased production of its cameras. The ubiquity of digital cameras had made their brand of instant photography a dinosaur. Who wanted to buy Polaroid film cartridges and take those blurry pictures, when you could snap photo after photo on your cell phone?
Enter “crazy Austrian entrepreneur” Florian Kaps, one of many hobbyists and artists who didn’t want to see Polaroids fade out. Just a day or two before $130 million in Polaroid film production machines were scheduled to be destroyed, Kaps bought the production equipment. He then hired some of the brightest Polaroid engineers, leased part of the Polaroid factory, and founded The Impossible Project.
Polaroid granted a license to The Impossible Project to create new instant film from scratch. One of the factors that made the project seemingly impossible was that the chemicals to create the film were no longer available – the chemicals need to be aged for two years before use, and after Polaroid cut its relationships with the suppliers, the chemicals were no longer produced. But the Impossible Project found new ways to manufacture the film by reverse-engineering from existing film and coming up with entirely new methods for other parts of the process (more technical explanations available in an interview with the founders).
Their new version of Polaroid instant film is now available at the-impossible-project.com. The film is not cheap, going for about $20 for one pack of 10 shots, black and white only, and the photos are decidedly artsy. Color film should be available soon.
Now that the film is once again being produced, Polaroid is reintroducing its OneStep, one of the most basic models. Interest in instant photography has been redeveloped, you might say, by doing the impossible.

Is small the next big thing in manufacturing?
Chris Anderson has written a phenomenal article about the democratization of manufacturing in a recent issue of Wired magazine. I cannot recommend the article enough, if for no other reason than the chance to learn about a lot of cool micro-manufacturing companies, like Jawbone manufacturer (and Arena customer) Aliph and open-source car company Local Motors, which has been featured previously in this blog.
There is one passage in particular that I would like to highlight. It’s a bit lengthy, but I think the point Anderson makes is strong and is best left as unabridged as possible. Here is his take on what’s driving this revolution (emphasis is mine):
The tools of factory production, from electronics assembly to 3-D printing, are now available to individuals, in batches as small as a single unit. Anybody with an idea and a little expertise can set assembly lines in China into motion with nothing more than some keystrokes on their laptop. A few days later, a prototype will be at their door, and once it all checks out, they can push a few more buttons and be in full production, making hundreds, thousands, or more.…
Today, micro-factories make everything from cars to bike components to bespoke furniture in any design you can imagine. The collective potential of a million garage tinkerers is about to be unleashed on the global markets… ‘Three guys with laptops’ used to describe a Web startup. Now it describes a hardware company, too.
‘Hardware is becoming much more like software,’ as MIT professor Eric von Hippel puts it. That’s not just because there’s so much software in hardware these days, with products becoming little more than intellectual property wrapped in commodity materials, whether it’s the code that drives the off-the-shelf chips in gadgets or the 3-D design files that drive manufacturing. It’s also because of the availability of common platforms, easy-to-use tools, Web-based collaboration, and Internet distribution.
We’ve seen this picture before: It’s what happens just before monolithic industries fragment in the face of countless small entrants, from the music industry to newspapers. Lower the barriers to entry and the crowd pours in.”
What do you think? Are we on the verge of the age of small-scale manufacturing? Are you seeing a lot of small start-ups in your market take advantage of these trends and technologies? Are YOU that small start-up??
Retro manufacturing: vinyl record pressing
I’m kind of a vinyl nerd. When things get hectic, I retreat to the man-cave in my garage, play some pinball and play my records on a little turntable perched on my workbench.
I’ve always been curious about the process for making vinyl records. I found the answer in a video filmed at Rainbo Records in Southern California that shows the record manufacturing process from end to end.
The basic process is that the sound pattern of music is fed into a computerized lathe, which cuts grooves into a master disc according to the tone–wider grooves for bass tones, narrower grooves for higher treble tones. That master disc is used to make multiple “mother” discs, which in turn are used to create negative “stamper” discs. These are then used to press the final records you buy in a shop where guys in ironic tee shirts flip through albums one by one.
Vinyl records are experiencing a resurgence in popularity. According to Rainbo Records, in 1977, 3 days after Elvis died, they were pressing 60,000 records per day. By the late ’80s, with the rise of the CD, that number was down to 8,000 to 10,000 per day. Now, thanks to the vinyl comeback, Rainbo is pressing up to 25,000 records per day.
Is this renewed popularity enough to change a manufacturing process that hasn’t changed much since the ’50s? Only time will tell.
Thoughts on outsourced manufacturing…inspired by the 2010 World Cup soccer ball
I was fascinated by the video in Marc’s recent post about the official soccer ball of the 2010 World Cup.
What struck me was the highly optimized combination of handwork and custom tooling involved in the manufacture of a high-quality commodity product. For example, the inner shell panels are die-cut from sheet (tooling), then sewn by hand into a sphere (a manual process), then manually inverted on a simple-but-still-custom fixture, and then inflated and molded to a perfect sphere in purpose-built spherical molding stations. This kind of high-volume custom-tooled manufacturing is evidence of years of manufacturing investment and optimization around a stable product design, and demonstrates one end of a spectrum. At the other end of the spectrum is lower-volume design-intensive and rapidly changing products (e.g. networking equipment) that use “generic” manufacturing processes like metal stamping, injection molding and PCB assembly.
I think mid-market manufacturers who are considering outsourcing should keep this spectrum in mind – if your product is more like soccer balls, in which the bulk of your intellectual property lies in your tooling and process rather than your product, then traditional outsourcing with a large contract manufacturer such as Solectron, Flextronics or Celestica is probably not going to make sense. You might still consider offshore manufacturing to reduce tooling and labor costs, but success requires that you “own” your manufacturing facility, at least emotionally if not legally. On the other hand, to succeed in making wireless routers you need to “own” your product design. With careful vendor selection and management, though, you can safely rely on a trusted third party to do your manufacturing using generic manufacturing processes and tooling. In many cases – especially with industrial products – a product combines design-intensive and commodity-tooled elements with a custom-tooled “special sauce.” For example, an optical assembly may require highly specialized manufacturing processes but produce an image that is then captured with an image sensor that is part of a custom—but easily manufactured—PCBA. A company manufacturing this kind of product might want to pursue a hybrid manufacturing model, using outsourcing for the electronic subassemblies but keeping the more specialized and tooling-intensive manufacturing steps in-house.
Take a look at this video showing an assembly line for the Xbox 360. Compare it to the soccer ball production video from Marc’s post and you’ll get a feel for the extreme ends of the manufacturing spectrum.
Adidas uses thermal-bonding, not stitching, to create perfectly round ball for 2010 FIFA World Cup
The official match ball for the upcoming FIFA world cup, the Adidas Jabulani, features a newly developed “Grip’n'Groove” surface for enhanced grip in all conditions and an exceptionally stable flight path. Thanks to a new spherical-molding process for the eight thermally-bonded panels, the ball is perfectly round and thus more accurate for passes and shots on goal.
Adidas has been manufacturing close to 1,800 of these a day since April 2009. What still remains to be seen, however, is whether a perfectly round ball is actually better for the game than hand-stitched ones, whose idiosyncrasies were said to keep goalkeepers second-guessing the ball’s flight path.

December 2009 PMI shows 5th straight month of manufacturing growth
The latest Institute of Supply Management (ISM) report on manufacturing, issued last week, finds that the PMI rose for the 5th consecutive month in December 2009 to 55.9%. New orders, production and employment were up, while inventories contracted and supplier deliveries slowed. The full report can be found on the ISM website.
Long considered one of the leading economic indicators, the PMI looks at the state of new orders, production, supplier deliveries, inventories and employment. ISM collects data in each area from supply executives at more than 400 industrial companies representing 20 industries across all 50 states, and then analyzes it to determine whether each area is improving or worsening. A PMI of 50% or above is generally considered a sign that the manufacturing economy is growing.
The Overview of the Manufacturing Report on Business (ROB) on the ISM website offers a full explanation of the PMI.
