FR4 PCB board is the most common PCB, usually found in many electronic devices. FR4 PCB boards are made of fiberglass and epoxy combined with laminated copper cladding. Some of the main applications of FR4 PCB boards are: Computer Graphics Cards, Motherboards, Microprocessor Boards, FPGAs, CPLDs, Hard Disk Drives, RF LNAs, Satellite Communication Antenna Feeds, Switch Mode Power Supplies, Android Phones, and many more.
With the rapid development of the PCB industry, FR4 PCB boards play an important role in medical equipment, industrial equipment, lighting, automotive and aerospace industries. What are the specific uses of FR4 PCB boards?
Application of FR4 PCB board 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 separate FR4 PCB boards, such as: pH meter, heartbeat sensor, temperature measurement, EKG machine, EEG machine, MRI machine, X-ray, CT scan, blood pressure machine, blood sugar level Measuring equipment, incubators and some medical equipment.
Application of FR4 PCB board in industrial equipment
FR4 PCB boards are widely used in the manufacturing industry, especially those industries with high-power mechanical equipment, which are driven by circuits that operate on high power and require high current. Therefore, a thick copper layer is laminated on the FR4 PCB, which is different from complex electronic PCBs, and these high-power PCBs have a current of up to 100 amps. This is especially important in applications such as arc welding, large servo motor drives, lead-acid battery chargers, military industry, and garment cotton machines.
Application of PCB board in lighting
We see ambient LED lights and high-intensity LEDs, these small LEDs that provide high-brightness light, are mounted on aluminum-based PCBs. Aluminum has the property of absorbing heat and dissipating it in the air. Therefore, due to the high power, these aluminum PCB boards are usually used in LED lamp circuits for medium and high power LED circuits.
Applications of FR4 PCB boards in the automotive and aerospace industries
Our most common reverberation generated during the movement of airplanes and automobiles uses a flexible PCB or a combination of flex rigid PCBs to meet these high-force vibrations and make the PCB flexible. Flexible PCBs are lightweight but can withstand high vibrations, which can reduce the overall weight of a spacecraft due to its light weight.
Even in a narrow space, flexible PCB can be adjusted, which is a great advantage it occupies. These flexible PCBs are used as connectors, interfaces, and can be assembled even in tight spaces, such as: behind panels, under dashboards, etc.
