5 Popular Devices That Use Printed Circuit Boards

Consumers and businesses alike depend on a variety of electronics on a daily basis. Although most electronic device users are not familiar with printed circuit boards (PCBs), they, too, play a major role in everyday life. After all, consumer electronics and industry-related devices require printed circuit boards to function properly. As a tech enthusiast, you are likely interested in how PCBs affect the technology world. Increase your knowledge on the subject by reading this post about the most popular devices that use printed circuit boards. You might be surprised at how many of these gadgets you use frequently. 


Firstly, printed circuit boards are in smartphones. Without a PCB, your smartphone would not be able to function. You would not be able to text your friends or call your family members. Even games would be impossible to play on your mobile device if it did not use a printed circuit board. With this being said, printed circuit boards significantly improved the way that consumers and businesses communicate. Keep in mind that the circuit boards embedded in your small smartphone differ from the ones in other devices. They need to be small enough to fit into a hand-held mobile phone and incredibly high-functioning to enable users to conduct so many tasks. This is one of the many popular gadgets that use printed circuit boards. 

Medical Devices

Similarly, medical devices require printed circuit boards to function. While smartphones allow you to communicate with your friends and family, medical devices allow trained healthcare professionals to perform a series of life-saving procedures. For this reason, electronics engineers use the best professional PCB design software available to build boards for medical devices. Doctors use the finished products to monitor patients, conduct tests and complete surgeries. If they end up using devices with defective printed circuit boards, their patients’ lives could be at risk. Hence, engineers who plan to build PCBs for popular medical devices need to ensure that they have the skills to do so properly. 

Motorized Vehicles

Additionally, electronics engineers build printed circuit boards for motorized vehicles. The automotive industry continues to add more and more technology into cars. In order for such technology to work, printed circuit boards are needed. The most that the industry used PCBs for in the past was to make windshield wipers and headlight switches work. Today, new cars have PCBs built into them for a wide variety of reasons. For instance, they enable cars to avoid collisions and monitor blind spots. They also play a major role in advanced cruise control settings. Without PCBs, modern cars would not be able to detect when other vehicles are in their blind spots, prevent drivers from getting into accidents or keep a safe following when cruise control is on. Motorized vehicles use printed circuit boards in many ways. 


Most consumers also use the ever popular computer, which is yet another device that uses PCBs. Whether you use a computer for work or you simply enjoy browsing the internet on one after a long day, you are rightfully taking advantage of printed circuit boards. As a tech enthusiast, you are likely familiar with what a motherboard is. They directly influence computer systems and, to many consumers’ surprise, they are actually printed circuit boards. In addition to the motherboard, computers have other PCBs in them as well. The other circuit boards power supplies and are in charge of random access memory (RAM). The next time you use your computer, think about how the PCBs inside of it are enabling it to function. 

LED Lights

Furthermore, LED lights are popular devices that use printed circuit boards. Many other electronic gadgets use LEDs and the circuit boards that make them up. Cars, medical instruments, computers and smartphones all require LEDs. Thus, the PCBs that enable them to function are important to various industries as well as consumers. Printed circuit boards perform numerous functions in LEDs. They transfer heat away from bulbs and, in turn, boost the life of LED lighting devices. As you carry on with your day-to-day activities, notice how often you use LEDs. This is another device that uses printed circuit boards.

Printed circuit boards affect everyday life more than most tech enthusiasts realize. Smartphones rely on PCBs to make calls and respond to texts. The healthcare industry has a major use for PCBs because they go into life-saving medical devices. At the same time, new cars use multiple PCBs to provide consumers with advanced technology features. Printed circuit boards also enable computers to perform tasks. Lastly, LED lights have PCBs in them and rely on quality ones to bring light to a variety of other gadgets. As you carry on with your day-to-day activities, keep in mind just how many electronic devices use printed circuit boards.
