Smart Factory Insights: Size Matters—The Digital Twin

In the electronics manufacturing space, at least, less is more. There are a whole plethora of reasons that have been driving down the size of electronic assemblies for many years—a trend which shows no sign of diminishing. The price we all have to pay as electronics manufacturers is not trivial, as existing paradigms of assembly, inspection, test, and quality control are challenged to the extreme. The digital twin is supposedly the new paradigm, yet—as with many things these days—the term has already been abused by various marketing teams to promote many disparate products and bespoke technologies, causing confusion, which stifles progress. Let’s consider what the true digital twin is really all about—including the components, uses, and benefits—and see that it is not just an excuse to show some cool 3D graphics.

Size Matters

Miniaturization, in one form or another, has led the way competitively between OEMs of key consumer devices—a phenomenon that has now stretched across the whole industry. The trend started back in the 1980s when portable consumer devices first appeared, and rivalries between the giant consumer device manufacturers became public. One great example was the launch in Tokyo by Sharp, who launched their smallest ever mini-disc player to huge media accolades. Attending the event was Sony’s president at the time, Norio Ohga, who—when asked about his reaction to Sharp having the smallest player in the world—took out of his shirt pocket what appeared to be a prototype of a player half the size, and said, “I don’t think so.”

Though with less fanfare, perhaps, the reducing size of electronics has been a continuous pursuit. It is not just a matter of being stylish and easy to carry. Sophisticated electronic controllers are now being integrated and embedded into the majority of everything that we own or use, including phones, energy meters, automotive intelligence, and military and space technology. There are many other factors apart from size itself that are important, including the weight; the space required for storage and transportation related to packaging; the amount of material consumption, especially for key materials for which there is a finite supply; the energy consumption of the device, including the safety of power supplies—especially batteries; and the physical strength of the device in terms of protection for example of an automotive module involved in a collision.

Smart Factory Insights: Recognizing the Need for Change


We are reminded many times in manufacturing, that "you cannot fix what you cannot see" and "you cannot improve what you cannot measure." These annoying aphorisms are all very well as a motivational quip for gaining better visibility of the operation. However, the reality is that there is a lot going on that no-one is seeing.

Accelerating Tech: Standards-driven, Digital Design Flow for Industry 4.0


The term “fragmented manufacturing” is a good way to describe current assembly manufacturing challenges in an Industry 4.0 environment. Even in Germany, productivity reportedly continues to decline. To reach the upside of Industry 4.0, data flows relating to design play a major role—one that brings significant opportunity to the overall assembly business.

The Truth Behind AI


The term "artificial intelligence" or "AI" has become a source of confusion for many—heralded as part of Industry 4.0, yet associated with the threat of automation replacing human workers. AI is software rather than hardware, and it's time to put these elements of AI into context, enabling us as an industry to embrace the opportunities that so-called AI represents without being drawn in, or pushed away, by the hype.

Resolving the Productivity Paradox


The productivity paradox continues to thrive. To a growing number of people and companies, this does not come as a surprise because investment in automation alone is still just an extension of Industry 3.0. There has been a failure to understand and execute what Industry 4.0 really is, which represents fundamental changes to factory operation before any of the clever automation and AI tools can begin to work effectively.

Perhaps in the future, sentient robots looking back at humans today will consider that we were a somewhat random bunch of people as no two of us are the same. Human actions and choices cannot be predicted reliably, worse even than the weather. As with any team however, our ability to rationalize in many different ways in parallel is, in fact, our strength, creating a kind of biological “fuzzy logic.”
