7 Applications of Printed Circuit Boards You Didn’t Know About

Having the thought to buy PCBA? Printed Circuit Boards Assembly (PCBAs) are a vital component of modern electronic devices, from cell phones to medical equipment. Despite their ubiquity, there are many applications for PCBAs that you may not have heard of. In this blog post, we will explore seven of the most innovative uses for PCBs that you may not have known about. From controlling robots to powering a car, PCBs are being used in ways that are transforming our world. Read on to learn more!

Communication systems

Printed Circuit Board Assembly (PCBA) is used in communication systems. It has been an integral part in the past and now its relevance has grown as the communication system now faces a modern age. You’ll find them in smartphones, routers, panels etc. 

Whatever the devices or systems employed, PCBAs are the core components. The board is designed to house components that make communication possible. These include RF filters, antennas, multiplexers, amplifiers, etc.

The PCBA is an innovation that has led to the production of portable communication devices. Little wonder there are communication devices of smaller sizes at this present time.

Automotive electronics

Take a look at the modern trends in the automobile industry. You’ll see vehicles with high-class gadgets in the interiors. These include the sensor systems, engine control unit and other devices at the dashboard of vehicles.

To mention some more, PCBAs are used in vehicle navigation systems, audio systems, speedometer, and fuel level sensors. 

Military electronics

One of the most important applications of Printed Circuit Boards (PCBAs) is in military electronics. PCBAs are used to produce a variety of complex electronic systems, including communications, navigation, surveillance, and weapons systems. Military PCBAs need to be designed and manufactured to meet stringent quality and reliability requirements and are usually tested for compatibility with extreme temperatures, shock and vibration, and electromagnetic interference.

These boards can be used for numerous purposes, such as controlling missiles and radar systems. PCBAs can also be used for communication systems and satellite control systems, which are essential for the operations of a military force. PCBAs allow for these systems to be created with smaller parts, which can reduce the weight and size of the system and make them easier to use and transport.

Another application of military PCBAs is in the production of night vision goggles and infrared detection devices. These devices can detect objects in low light conditions and provide soldiers with an edge in nighttime combat situations. Additionally, PCBAs are used in a wide range of airborne devices, such as autopilots, GPS receivers, and sonar systems.

Military PCBAs require extremely robust design specifications, so they must be designed and produced to exacting standards. These boards must be resistant to high levels of temperature and moisture, as well as mechanical shocks, vibrations, and electrical interference. With proper care and maintenance, these boards can provide reliable performance over a long period of time.

Medical electronics

Medical electronics refers to the application of electrical and electronic engineering in medical science. It includes the design, development and manufacture of medical devices, systems and components that are used to diagnose, monitor, treat and prevent illnesses and diseases. Examples of medical electronics products include pacemakers, hearing aids, ventilators, imaging systems, monitoring devices and various other implantable devices.

Medical electronics also involves research and development of new technologies and techniques to improve the efficiency and accuracy of medical care. In addition, it involves the use of specialized materials such as biocompatible polymers, ceramics and nanomaterials to develop medical devices. 

Printed circuit boards (PCBs) are used extensively in the design of medical electronics. They provide the necessary connections between components and enable the efficient delivery of electrical signals from one component to another. Furthermore, PCBs allow for the integration of multiple components into a single system, making them highly reliable and cost-effective solutions for medical electronics.

Power supplies

Power supplies are an essential part of any electronic device and printed circuit boards (PCBAs) are used to produce these components. A PCBAs power supply includes the circuits required to convert AC power from the grid into a DC power needed to run the device. This includes circuits that regulate the current, voltage, and frequency of the output power.

PCBA power supplies are used in many different industries including medical, aerospace, industrial, automotive and consumer electronics. The advantage of a PCBAs power supply is that it can provide a reliable power source for a wide range of devices and applications. Additionally, it is relatively inexpensive and can be easily replaced if necessary.

One of the most common applications for PCBAs power supply is in LED lighting. LED lighting requires a stable and constant power supply and PCBAs provide this at an efficient cost. Additionally, LED lighting can benefit from PCBA technology because the circuit boards are small and compact so they don’t take up valuable space in the lighting unit.

PCBA power supplies are also used in renewable energy applications such as solar panels, wind turbines, and fuel cells. In these applications, the PCBAs power supplies are able to efficiently convert DC power generated by renewable sources into usable AC power that can be used to power homes and businesses.

Overall, PCBA power supplies are essential components of many electronic systems, providing reliable and efficient power solutions for a wide range of applications. From LED lighting to renewable energy solutions, PCBAs power supplies are an integral part of modern technology.


PCBA has triggered immense upgrades when it comes to lighting. Rolling back the years is the era when lighting depended on too much wire and bulk switches. However, with PCBAs we now see portable and fancy lighting fixtures.

PCBAs make it possible to have lighting controlled by small or even smart switches. This era of lighting has proved efficient and versatile. 

Examples of PCBA applications in lighting include LED light fixtures. Today, there are LED lights of different modes such as dimmable LED and LED strips which are flexible and a major tool for fancy lighting. 

Renewable energy

Renewable energy is a booming aspect of human life right now. They have triggered the invention and adoption of solar power, inverters, photovoltaic panels, hydroelectric power generating systems etc. The PCBA is a major influence in this progress and all the above mentioned systems comprise of PCBA circuitry. 

Examples include solar panels, and panels for other renewable energy systems. These mode of operation are super efficient, economical, and easier to manage. They provide a miniaturized way of generating energy.


The PCBA has undoubtedly revolutionized technology to something more appreciable and easier to use. PCBAs are the core for several electronic devices used across several industries. They can be used in communication systems, lighting, renewable energy, medical electronics, military electronics, power supplies, and automotive electronics.
