IoT is the Internet of Things, which includes objects with built-in sensors, software and other technologies.

They interact with other objects through communication systems, for example, the Internet.
It is believed that the creation of the Internet of Things has become the 4th industrial revolution, and it is getting bigger every day. The concepts of IoT include smart home (light sources, thermostats, security system, household appliances and cameras), smart car and smart city.
The Internet of Things is developing through computing, sensors, embedded systems, and machine learning.
Internet of Things and PCBs
The development of IoT contributes to the development of PCB manufacturing.
PCBs for the Internet of Things
The main task of developing printed circuits for the Internet of Things is to create a high-tech PCB that works equally efficiently in any form. IoT uses flexible PCBs and HDI PCBs (with high trace density). They satisfy high power conditions, provide freedom of circuit design, and withstand heavy loads.

Previously, PCBs made of traditional flame-resistant FR4 material were used. During the development of the Internet of Things, schemes should be easily integrated and flexible. For these reasons, printed circuits from new materials such as flexible-rigid copper, plastic and mesh are developing in the IoT.
Advantages of flexible PCBs for IoT
Flexible PCBs are made of ultrathin and ultralight polyester or polyetherimide film, which has increased density and flexibility.
The main advantage of such PCBs is that they reduce the design limitations that may arise when using rigid PCBs. Such a PCB has a number of advantages that favorably distinguish it from analogues:
Advantages of using HDI PCBs in IoT
HDI PCBs are also used in the Internet of Things.
They help to ensure high density for good circuit performance. Advantages of HDI in the Internet of Things:
– Reduced cost.
– Small size. Flexible PCBs allow to save space and maintain the density of circuits.
– Small weight. It helps to reduce the weight of the entire circuit, which allows the devices to be more versatile and be used in surgical equipment or hearing aids.
– Durability. This makes PCBs more resistant to loads, i.e. shocks or vibrations. They can be used in fitness watches.
– Simplified wiring methods. This advantage is achieved because there are no mechanical connectors in flexible PCBs.
– Small weight and size. This is achieved due to the reduced track width and high trace density, which saves space on the PCB.
– More wiring options. Thanks to vias and micro-holes, wiring possibility is universal. This allows to achieve better signal quality.
– High energy efficiency. PCBs allow to create devices that are more cost-effective to implement, thanks to energy efficiency and the least need for layering.
Printed circuit boards are designed for IoT taking into account the requirements that allow PCBs to meet all standards:
PCB design for the Internet of Things
— Meet the size requirements. Since many devices are getting smaller, printed circuit boards should also shrink without loss of quality and properties.
— Adapted to the human body. With the development of the Internet of Things, devices for human interaction, for example, fitness trackers, are also being optimized.
— Increased operating time of the devices. Since devices are constantly switched on and connected to the networks, PCBs must ensure the continuous operation of the devices.
— Reliability. Device reliability standards are constantly being improved, so PCBs must comply with these standards.
— Internet access. PCBs must support constant access of devices to the Internet.
Printed circuit boards provide almost every device in the IoT.
