The Internet of Things or IOT is a hot buzz word that just about everyone needs to know about. We live in a technical society today and IOT is powering our society. The purpose of IOT is to increase connectivity between the digital and physical worlds. Another term for IOT is the infrastructure of information society. It has paved the way for intelligent connected platforms by using innovative devices like medical monitoring devices, home automation devices, and wearable devices. These connected devices are controlled remotely to provide economic gain, accuracy, and improved efficiency. Thus, new approaches to PCB designs are propping up.

How IOT Drives New PCB Approaches?

When it comes to the world of PCB, it is continuously innovating itself to catch up with customer demands. Most people look for devices which are smaller and process information much quicker. This is powering new PCB design approaches. PCBs are highly demanded because there is a need for smaller devices which can connect to IOT and offer HDI (High Density Interconnect). Fitness trackers and various small devices require flex PCBs as it allows for more components to be added in the limited space.

Complicated wiring is simplified by using flex PCBs and it even provides extra resistance in harsh conditions. Higher performance and lower power consumption have become common due to HDI design approaches which makes them perfect for IOT devices. HDI and flex approaches can be combined to PCB designs to provide companies with the ability to produce smaller devices without having to compromise on performance, as microvision lab suggests. However, designers need to know about the design requirements for IOT applications as mentioned below.

  1. Extended Battery Life

Design for IOT requires the consideration of extended battery life since IOT device tend to be always communicating with the network. Thus, it is crucial that battery life be extended through the design of the product. It is due to this reason that optimization of power consumption and analyzing the power integrity is a common requirement during the design phase.

  1. High Standards

Consumers are becoming more and more dependent on IOT devices. This is why the standards of quality are rising. People need to trust that the device would be accurate and operation as technological changes are made. Hence, PCB designers would have to rely on simulation programs to prototype the design virtually in software for various conditions.

  1. Security

Security has to be updated since millions of devices will be connected to the IOT. However, security updates through software would not be sufficient and hardware-based security mechanisms will need to be implemented to provide an extra layer of protection.

  1. Flexibility & Size

IOT applications are normally small due to necessity. Flexibility and size are physical limitations which need to be considered by PCB designers. Functionality requirements can be met by using approaches like HDI and rigid-flex.


IOT is rapidly evolving and PCB designers have to keep up with the trends in order to succeed. When designers understand certain requirements and restrictions to creating connected IOT devices, designers will be better able to design the right device.
