What are the main applications of PCB boards?

PCB board is also called printed circuit board. Strictly speaking, printed circuit board is represented by PCB instead of "pcb board". PCB is the provider of electrical connections for electronic components and is the core of electronic equipment. It can be of any shape or size, mainly depending on the application of the electronic equipment.

So, what are the main applications of PCB boards?

?

FR-4 is the most common substrate/base material for PCB. It is commonly found in many electronic devices and is also the most common smart manufacturing. FR-4 (PCB) is made of fiberglass and epoxy combined with laminated copper cladding. Some of its major applications: Computer Graphics Cards, Motherboards, Microprocessor Boards, FPGAs, CPLDs, Hard Drives, RF LNAs, Satellite Communication Antenna Feeds, Switch Mode Power Supplies, Android Phones and many more.

With the rapid development of the printed circuit board industry, it plays an important role in medical equipment, industrial equipment, lighting, as well as the automotive and aerospace industries. Let's take a look at the specific uses of PCB boards.

1: Application of PCB in medical equipment

?

Today's rapid progress in medical science is closely related to the rapid development of the electronics industry. Many microbial equipment and other equipment are based on individual PCBs, such as: pH meters, heartbeat sensors, temperature measurements, electrocardiographs, electroencephalographs, magnetic resonance imaging machines, X-rays, CT scans, blood pressure machines, blood sugar level measuring equipment , incubator and some other medical equipment.

2: Application of PCB in industrial equipment

?

PCBs are widely used in the manufacturing industry, especially those industries with high-power mechanical equipment, which run on high power and require high-current circuit driving. Therefore, a thick layer of copper is laminated on the PCB, unlike complex electronic PCBs, these high-power PCBs draw currents up to 100 amps. This is particularly important in applications such as arc welding, large servo motor drives, lead-acid battery chargers, military industry, clothing cotton machines, etc.

3: Application of PCB in lighting

?

We see LED lights and high-intensity LEDs around. These small LEDs provide high-brightness light and are mounted on PCBs based on aluminum substrates. Aluminum has the property of absorbing heat and dissipating it in the air. Therefore, due to the high power, these aluminum circuit boards are commonly used in LED light circuits for medium and high power LED circuits.

4: PCB applications in the automotive and aerospace industries

?

Our most common reverberation caused by the movement of airplanes and cars uses a type of PCB called Flex PCB to satisfy these high-force vibrations and make the PCB flexible. Flexible PCBs are lightweight but can withstand high vibrations, reducing the overall weight of the spacecraft because of their light weight.

?

Even in a narrow space, flexible PCB can be adjusted, which is a great advantage it occupies. These flexible PCBs serve as connectors, interfaces, and can be assembled even in tight spaces, such as behind panels, under dashboards, etc.
