PCB board is also called printed circuit board, strictly speaking printed circuit board is the use of PCB to express, rather than using "PCB board". PCB is the provider of electrical connections for electronic components and is the core of electronic equipment. It can be any shape or size, depending on the application of the electronic equipment.
So, PCB board is mainly used in what aspects?
As the most common substrate/substrate material for PCB, FR-4 usually exists in many electronic devices and is also the most common intelligent manufacturing. Fr-4 (PCB) is made from glass fiber and epoxy resin combined with a laminated copper cladding. Some of its main applications: computer graphics card, motherboard, microprocessor board, FPGA, CPLD, hard disk drive, RF LNA, satellite communication antenna feed, switch mode power supply, Android mobile phone and so on.
The application of PCB in medical equipment
Nowadays, the rapid progress of medical science is closely related to the rapid development of the electronic industry. Many microbiological equipment and other equipment are single basic PCB, such as: pH meter, heartbeat sensor, temperature measurement, electrocardiogram machine, electroencephalogram machine, nuclear magnetic resonance imaging machine, X-ray, CT scan, blood pressure machine, blood glucose level measurement equipment, incubator and other medical equipment.
The application of PCB in industrial equipment
PCBS are widely used in manufacturing, especially in industries with high-power mechanical equipment that runs on high power and is driven by circuits that require high current. As a result, a thick layer of copper is placed on top of the PCB, unlike complex electronic PCBS, which have high power currents of up to 100 amperes. This is especially important in arc welding, large servo motor drivers, lead acid battery chargers, military industry, clothing cotton machines and other applications.
Three: PCB in the application of lighting
We see around us LED lights and high intensity leds, these small leds that provide high brightness light, are mounted on a PCB based on an aluminum substrate. Aluminum has the property of absorbing heat and dissipating it in air. Therefore, due to the high power, these aluminum boards are commonly used in LED lamp circuits for medium and high power LED circuits.
Four: PCB in the automotive and aerospace industry applications
The most common type of reverberation that we see in airplanes and cars is the use of a PCB called Flex PCB, which is designed to meet these high-force vibrations and make the PCB flexible. Flexible PCBS are lightweight, but can withstand high vibrations because of their light weight, which can reduce the overall weight of the spacecraft.
Flexible PCBS have a big advantage because they can be adjusted even in narrow Spaces. These flexible PCBS serve as connectors, interfaces, and can be assembled even in compact Spaces such as behind panels, under dashboards, etc.
