They are in your computers, stereo systems and even your mobile phone, but what are they? Printed circuit boards have taken the world by storm, providing us with endless convenience and entertainment, but which industries use them the most prevalently?
What is a printed circuit board?
A printed circuit board is often referred to as a PCB, and they are made from a thin insulation material. They have a metal-coated surface laden with etches made from acid. Although they provide many advantages, the main selling point is their compact nature. Resistors and capacitators can be easily welded into the holes drilled within them through the process of automation.
Medical
When working in the medical industry, PCBs play an abundantly important role in both diagnosing and treating patients with certain health conditions. Due to their structure, they are able to fit into even the smallest of mechanisms, such as implantable devices.
You can expect to see them in screening technology, such as CT scanning machines and x-ray devices. PCBs have longevity in this sector through their resistance to thermal degradation and dissipation, making them the ideal candidate for all kinds of equipment. They help to save lives every day.
Telecommunication
PCBs are extremely common in the telecommunications industry. They are found in everything that connects you with your friends and colleagues, from military communication systems to broadband equipment. Your router also has one of these inside it, allowing it to function perfectly. The lightweight boards can fit inside a mobile phone or transportable device without weighing you down and that is a very good reason why they are so favourable amongst these companies.
Defence
This might be a less obvious one, but did you know that the defence industry loves PCBs? They use them in their navigation and communication systems, LED lighting, simulators and robotic systems, alongside many other purposes. Not only do the boards provide one of the best sources of quality for the manufacturers, which is crucial during an emergency, but they are also really reliable.
Oil and gas
Fuel also needs circuit boards. The necessary machinery requires a printed circuit board to keep it functioning properly. When looking for oil and gas in the drilling process, PCBs are used to control the positioning and angle of the drill head. Similarly, renewable energy is now becoming commonplace, and both converters and generators make full use of PCBs.
Aerospace
Aerospace devices are known for their dynamic designs and their ability to be as weightless as possible to conduct their jobs. Aeroplanes and satellite equipment need to use mechanics that weigh less than the average parts, so PCBs are a great fit.
Automotive and rail
The navigation, audio and visual systems in a car or industry-standard public transport vehicle are powered by PCB boards to make sure your ride is safe and comfortable. Rail travel relies on braking systems which are largely controlled by PCBs. They use a special kind of board which is much more durable than the average PCB.
Industrial
If you have any machinery or equipment such as LED lighting systems, printers and coffee makers in your home or office, every one of these will be fitted with a PCB. Plus, a wide range of the boards are available in different brands of products, and each one ensures that we can live our lives to the fullest.
