From kitchen appliances to smartphones to microwaves, electronics play an essential role in our daily routines. Found at the heart of almost all electronics is a PCB or printed circuit board. In the modern world, PCBs act as the significant functional centers of almost all electronic devices. These small chips come in an uncountable number of configurations and are manufactured with different types of materials.

We at WellPCB have explored ten common uses of these applications in more detail, as highlighted below. 

PCBs–Medical Apparatus

Printed circuit boards continue to contribute heavily across the medical field. PCBs are used as appliances here and in devices meant for monitoring/observation, diagnostic, and treatment. The use of PCBs across the medical sector is rapidly growing, leading to new possibilities. Some of the most common applications of PCBs across the medical field include:

Monitors: Monitoring devices such as blood pressure, heart rate, and glucose monitors consist of electronic components. 

Medical Instruments: PCBs are in medical devices such as control systems, electronic microscopes, and compressors, among others. 

Scanning Devices: CT scanners, X-Ray screens, and ultrasound scans consist of electronic components to function. 

As it appears, the use of PCBs across the health sector is extensive. Even though medical printed circuit boards tend to be smaller, their use is vast and diverse. Looking around today, a majority of medical devices have PCBs in them, unlike before. 


Consumer Electronic Components

Consumer electronics consist of everyday devices we use, such as computers, smartwatches, and tablets, among others. Even the latest models of refrigerators make up the list of electronic components. In every one of these electronic components is a printed circuit board. The applications of printed circuit boards in consumer electronic components are extensive. 

The following encompasses just a few common uses of printed circuit boards in the field of consumer electronics:

  • Computer Electronics: laptops and desktops contain PCBs within their cores, and so do peripheral devices and screens that are associated with them. 
  • Mobile Devices: Tablets and smartphones find to use daily. They act as alarm clocks to GPS devices and contain PCBs in them. 
  • Recording Equipment: Digital cameras, microphones, and camcorders, among other recording equipment, rely on PCBs for practical functionality. 
  • Home and entertainment appliances: Alarm clocks, coffee makers, DVD players, and TV sets run on electronic components.

Motor Vehicle/Automotive Use

A few years back, cars consisted of a few electronic circuits, but such is not the case as of today. Unlike before, the new automotive sector now features cars that rely on a vast range of electronics and computerized components that offer more functionality. Here are some of the significant applications of printed circuit boards in cars/vehicles:

  •  Proximity Monitors: A majority of the latest models of cars consist of built-in sensory devices to help drivers judge distances and monitor blind spots. These systems rely on PCBs for practical functionality. 
  •   Media Equipment: Modern cars have got advanced dashboards with the ability to connect to media or radio player. All these utilize electronic components. 
  •   Navigation: Navigation systems are increasingly becoming incorporated into cars. These systems rely on printed circuit boards to function as desired. 
  •   Control Systems: Advanced vehicle control systems such as fuel regulators, power supplies, and engine management all rely on PCBs. All these are necessary to monitor and manage nearly all parts of the vehicle.

Industrial Devices/Components

Nearly all industries rely on high-powered devices to control the mechanisms needed in production and manufacturing. Industrial components also rely on printed circuit boards to function. Again, these electronic components have to survive some of the toughest conditions, such as rapid vibrations, harsh chemicals, and rough handling. Typical uses of PCBs here include:

  • Power Devices: Power inverters such as DC-to-AC, power control equipment, and solar congregation devices, among others need PCBs to function. 
  •   Measuring Devices: Devices meant for measuring and controlling temperature and pressure in the manufacturing process have PCBs in them.
  •   Industrial Components: A majority of presses and electric drills used across the manufacturing sector operate on PCB-controlled electronic devices.

Scrutinized, LED lighting seems to be gaining popularity and is highly valued based on low power consumption, excellent light output, and high efficiency. Lately, PCBs are providing a versatile base across full applications of high-output LED devices. Better yet, their versatility increases the most when they get integrated with PCBs. 

PCBs are lately facilitating increasing uses for LED lighting solutions, especially in areas such as indicators and displays. Some significant applications/methods of PCB LEDs across the lighting industry include:

  •   Computer Technology Sector: PCB-based LEDs find use across the computer technology sector, mainly located in laptop and desktop displays. 
  •   Storefront and Residential Application: Business entities and homes rely on PCB-based lighting solutions in the form of presentations and signage. 
  •   The Medical Sector: Lighting tools, especially those used in emergency and surgical used LED-powered devices to aid physician’s visibility.

Aerospace Components/Devices

Just like automotive applications, plenty of aerospace devices require PCBs to function as desired. Whether rigid or flexible, PCBs are essential in powering aerospace components such as rockets, jets, and other devices used here. Major aerospace applications of printed circuit boards include:

•  Testing Devices: The development and test of air vehicles require PCBs. Testing devices collect data during such procedures and consist of PCBs. 

•  Monitoring Devices: Devices such as pressure sensors, accelerometers, microphones, and pressure sensors, among others, rely on PCBs for functionality. These components find use in cockpits and engines of rockets and airplanes to monitor the functionality of the vehicle and communicate back with ground control.

Electronic Security

Among other things that matter a lot, safety and security of oneself and property make it to the list. Lately, a lot of home and business owners value the safety and security of their property. For this reason, you are likely to see security cameras, electronic door locks, burglar alarms, motion sensors, and CCTVs almost everywhere. 

Safety and security equipment play an essential role, but surprisingly, many people don’t know that such devices need PCBs to function as desired. Regardless of whether they are flexible or rigid, safety and security appliances have got PCBs at their core. To effectively work as desired, these security footage appliances must rely on PCBs.

Retail Industry Devices

Many organizations in the retail industry rely on electronic components such as digital cameras, point-of-sale devices, counter illumination, illuminated POS stands, and freezer monitors. All these devices and many others are necessary for the smooth operation of daily business undertakings. Without them in place, businesses in the retail sector would experience delays and customer frustration. 

Again, the retail industry heavily relies on printed circuit boards found at the heart of their electronic components such as POS devices. The retail sector is increasing, and so are printed circuit boards that ingredients used in this sector rely on for daily use.

Defense Industry

Across the defense sector, there are plenty of devices that are purely PCB-driven. Nearly all the tools used in this industry operate under extreme or severe conditions with PCBs used in them supposed to withstand such conditions. Apt examples of

PCB-driven applications include Integrated Air Defense Systems, Signal Sensors, Command and Control Systems, and Auxiliary Power Units. 

The above is not all. Others include Jamming Systems, Airborne Early Warning and Control, Cyber Counterillegence Systems, and Advanced Medium-Range Range Air to Air Missile among other equipment used here. These devices must rely on PCBs to function and protect military personnel from danger or death.
