The Vision: Virtual to Support Real Operations
August 23, 2023 | Óscar Martins, Critical ManufacturingEstimated reading time: 1 minute
It’s time to make the ideal of digital transformation a reality. Everyone seems to agree that is the path to manufacturing business success. Yet, not everyone knows how to proceed toward this digital future right now.
Hint: Combine the new Industry 4.0 technologies such as digital twin and augmented reality (AR) with up-to-date versions of proven software systems, particularly manufacturing execution systems (MES). Or better yet, find systems that inherently do that for you. Then create ways to ensure these digital and virtual systems reflect and fully support your physical and real operations.
There are many new technology approaches to consider in Industry 4.0. Here, we will focus mainly on two: digital twin and augmented reality (AR) and point to a third, digital thread, which is more an ideal data flow and approach that ties other technologies together.
Digital twin is a digital replica of a physical entity. While common in product design, that is just one type of digital twin (Figure 1). In manufacturing, it’s the set of models and data about a product, asset, production line, or plant that is continually updated through its lifecycle. Using Industrial Internet of Things (IIoT) data allows real-time updates to the virtual model based on what’s happening in the real system.
Augmented reality (AR), as defined by MESA International, is: “Adding a virtual layer of contextual information at the right time and in the right place (e.g., through devices such as Google Glass). Augmented reality is expected to help plant floor workers perform a variety of non-repetitive tasks faster, such as assembly, picking, maintenance, and others.” The virtuality-reality continuum is a way to understand the relationship between the virtual and real worlds (Figure 2). Notice that there are also various mixes of virtual and real, notably augmented reality.

Bridging the Gap Between PCB Designers and Fabricators
04/03/2025 | Stephen V. Chavez, Siemens EDAWith today’s advanced EDA tools, designing complex PCBs in the virtual world does not necessarily mean they can be built in the real world. This makes the relationship between a PCB designer and a fabricator pivotal to the success of a project. In keeping with solid design for manufacturing (DFM) practices, clear and frequent communication is needed to dial and lock in design constraints that meet expectations while addressing manufacturing concerns.

Connect the Dots: Stop Killing Your Yield—The Hidden Cost of Design Oversights
04/03/2025 | Matt Stevenson -- Column: Connect the DotsI’ve been in this industry long enough to recognize red flags in PCB designs. When designers send over PCBs that look great on the computer screen but have hidden flaws, it can lead to manufacturing problems. I have seen this happen too often: manufacturing delays, yield losses, and designers asking, “Why didn’t anyone tell me sooner?” Here’s the thing: Minor design improvements can greatly impact manufacturing yield, and design oversights can lead to expensive bottlenecks. Here’s how to find the hidden flaws in a design and avoid disaster.
