With a growing demand to access new internet technologies, IoT applications are now influencing PCB design, fabrication, and assembly process for optimization.
Internet of Things (IoT) is a network of smart objects that gather and share data in real-time, over the internet or any communication network. These smart devices include sensors to collect data and software, with associated technology to process the acquired data.
IoT applications cover a wide range from consumer electronics like smartphones, wearables up to Industrial IoT (IIoT) like manufacturing, Healthcare monitoring equipment, etc. The ability to connect smart sensors with traditional electronic equipment has opened up various opportunities in the fields of agriculture, biomedical, automobile industries. The connected sensors provide data and are controlled remotely. This improves the efficiency and yield of the IoT product to a great extent.
With a growing demand to access new internet technologies, IoT applications are now influencing the PCB design, PCB fabrication and manufacturing process for optimization.
It is important to understand the internal circuitry requirements for different form factors of IoT products. Flex PCBs and high-density Interconnect (HDI) PCBs are the best choices in these applications. They meet high-power requirements in compact board sizes along with constant device stress endurance.
We shall discuss some of the design requirements of an IoT PCB:
Considering the above unique design requirements, we shall list out the recommendations for an optimized IoT PCB Design:
Some exclusive features of Flex PCBs and HDI PCBs enable them to be the best fit for IoT applications. Flex PCBs allow components to fit in a small space reducing the product weight. Flex PCBs remove the need for mechanical connectors and this simple wiring circuit turns out to be a great advantage in IoT applications. HDI PCBs provide speed and reliability that are critical in IoT applications. They offer excellent wiring density and tiny trace width which makes them smaller in size and distinct in circuit routing. The combination of Flex PCBs and HDI PCBs shall bring out an exceptional IoT PCB design with good signal integrity and lesser thermal stress.
Many IoT applications work at very high frequencies and the massive growth of consumer IoT applications has choked the RF spectrum. This has led to unwanted interference and safety issues. Designing an IoT PCB for User Safety is very important. PCB designer has to include shielding for sensitive devices to reduce the EMI hazards. A good grounding scheme provides immunity against interference issues.
Based on the IoT applications, the PCB design guidelines have to be optimized to deliver a high-performance IoT product. We have discussed the design, layout, and safety requirements to build a successful IoT PCB. You can contact a PCB assembly provider to assist you in bringing out your next IoT product into the market.
