PCB is also called a printed circuit board. Rigorously, printing circuit boards are represented by PCB, rather than using "PCB boards". PCB is a provider of electronic component electrical connection. It is the core of electronic devices and can be any shape or size, which mainly depends on the application of electronic equipment. So, in what aspects of the PCB board?

　　FR-4, as the most common base/base material for PCB, usually exists in many electronic devices and is also the most common intelligent manufacturing. FR-4 (PCB) is made of glass fiber and epoxy resin to combine with layer-pressed copper layer. Some of its main applications: computer graphics cards, motherboards, micro -processor boards, FPGA, CPLD, hard disk drive, RF LNA, satellite communication antenna feed, switch mode power supply, Android phone, etc.

　　With the rapid development of the printing circuit board industry, it has a significant role in medical equipment, industrial equipment, lighting, and automobiles and aerospace industries. What are the aspects of the specific PCB board? The following editors are analyzed one by one.

　　One: The application of PCB in medical equipment

　　The rapid progress of medical science is closely related to the rapid development of the electronics industry. Many microorganisms and other equipment are separate basic PCB, such as: pH meter, heartbeat sensor, temperature measurement, electrocardiogram machine, EEG image machine, X -ray, CT scanning, sphygmoman, blood sugar level measurement equipment , Culture box and other medical equipment.

　　Two: The application of PCB in industrial equipment

　　PCB is widely used in manufacturing, especially those industries with high -power machinery equipment. These equipment rely on high -power operation and require high -current circuits. Therefore, it is necessary to press the thick copper layer on the upper layer of the PCB, which is different from complex electronic PCB. These high -power PCB currents are as high as 100 ampel. This is particularly important in arc welding, large servo motor drive, lead -acid battery charger, military industry, clothing cotton machine and other applications.

　　3: Application of PCB in lighting

　　We see the surrounding LED lights and high -strength LEDs. These small LEDs can provide high brightness light, which is installed on an aluminum -based PCB. Aluminum has the characteristics of absorbing heat and dissipating in the air. Therefore, due to high power, these aluminum circuit boards are usually used in the middle and high -power LED circuits of LED lamp circuits.

　　Four: The application of PCB in the automotive and aerospace industry

　　The sound of our most common aircraft and cars use a PCB called Flex PCB to meet these high -power vibrations and make PCB flexible. Flexible PCB weight is light, but it can withstand high vibration. Because of its light weight, it can reduce the total weight of the spacecraft.
