The Internet of Things, otherwise known as IoT, refers to a network of interconnected electronic devices that exchange and communicate data with each other over the internet without human intervention. From household appliances to infrastructure components, every IOT device must meet one key requirement – connectivity.

Printed circuit boards (PCBs) can be seen as the backbone of most modern electronic devices, serving as the foundation for the electronic connections and components that allow IoT to exist. Without PCBs in IoT, IoT devices wouldn’t be able to achieve the size, functionality and interconnection that is required to revolutionise multiple industries

In this article, we’re going to explore the vital role PCBs play in enabling connectivity, innovation and intelligence that define both IoT and Industry 4.0.

The crucial role of PCBs in IoT devices

PCBs play an important role in IoT devices and are crucial for their functionality, performance and reliability. Without them, the capabilities of IoT devices wouldn’t be possible.

There are numerous ways that PCBs contribute to the effectiveness of IoT devices. PCBs in IoT serve as the backbone for component integration, which is vital for the functionality of IoT devices. From microcontrollers and sensors to communication modules such as Wi-Fi and Bluetooth, PCBs make it possible to integrate these components into an efficient, reliable system. This connectivity is a necessity for IoT devices to exchange data with other devices and drive innovation in today’s technologically advanced, connected world.

Another key benefit of PCBs in IoT is their flexibility and the ability to customise them to meet the particular requirements of IoT applications. PCB designers can adjust the size and functionality of the PCB according to its intended use. This flexibility allows IoT devices to meet the demands of different performance levels, environmental conditions and connectivity options. 

What is Industry 4.0? 

Industry 4.0, also known as the Fourth Industrial Revolution, is the next phase of the manufacturing sector which is driven by digitisation, digital technologies and the rise of data and connectivity. You can think of Industry 4.0 as today’s industrial revolution, taking what started in the third revolution (Industry 3.0) through the adoption of computers, and taking it one step further with smart and autonomous systems driven by machine learning.

Today and as Industry 4.0 continues, computers are connected and communicate with each other to make decisions without the need for human intervention. These technological advancements intend to digitise the manufacturing process, to allow quality products to be made with enhanced efficiency, but at a lower cost. 

If you’re wondering how Industry 4.0 and PCBs work together, it’s all about automating the PCB manufacturing process. As computers continue to develop and advance, machines can learn PCB assembly tasks and errors can be rectified early by adjusting the assembly setup. This allows production yield, the percentage of non-defective items, to increase significantly as automation reduces the risk of human error.

PCBs powering smart manufacturing and Industry 4.0

PCBs are invaluable when it comes to powering smart manufacturing and Industry 4.0 initiatives. From enabling interconnected systems and IoT integration, to automation and flexibility, PCBs will continue to play a pivotal role in shaping the future of the manufacturing industry. 

Here are just some examples of how PCBs are powering smart manufacturing as we work towards Industry 4.0:

  • IoT integration: As mentioned, PCBs are the physical hardware backbone of IoT devices. By incorporating these devices and sensors into the manufacturing process, valuable data can be collected to inform designers of equipment performance, energy consumption and overall product quality. This grants manufacturers insight into production efficiency and any quality control measures that need to be taken.
  • Remote monitoring: By connecting machinery to centralised control systems via IoT devices, manufacturers can monitor PCB performance metrics wherever they are in the world. Remote monitoring allows manufacturers to oversee the whole production process, detect errors and anomalies and intervene where needed to improve production efficiency. 
  • Improved flexibility: PCBs allow manufacturers to develop their operations in line with the technological advancements of Industry 4.0. They offer flexibility in manufacturing systems, making the integration of additional components straightforward. What’s more, whether you’re upgrading existing equipment with new sensors or improving control features, adapting your operations to meet market demands shouldn’t be a problem. 

PCB design and manufacturing trends for the IoT era

In the IoT era, the design and manufacturing of PCBs are continuing to evolve to meet the demands of its small, connected devices. For you to get ahead of the curve and keep up-to-date with the latest advancements in the industry, we’ve put a list of notable trends together that are shaping PCB manufacturing for the IoT.

  • Flexible and rigid-flex PCBs: IoT devices often need flexibility to fit tight spaces and different shapes. Both flexible and rigid-flex PCBs allow for bendable and foldable designs due to their flexed shape, ideal for IoT devices by reducing the reliance on connectors and cables. 
  • HDI PCBs: High-density interconnect PCBs allow design freedom and flexibility. They’re known for their smaller size, higher line density and quicker signal transmission speed, allowing them to accommodate smaller, more integrated IoT devices.
  • Security: Security is a top priority for IoT devices to protect sensitive data. PCB manufacturers can incorporate hardware security features into their designs, such as secure elements and cryptographic coprocessors, to help safeguard IoT devices against cybersecurity threats.
