PCB News - Application of Printed Circuit Board

Printed circuit board is manufactured using the process of circuit board printing, so PCB board are also known as printed circuit board. Strictly speaking, printed circuit board are represented by PCB, not by "PCB board".

Printed circuit board can be found in various types of small and large electronic products, such as buzzers, computer systems, radars, etc. They help improve the carrying capacity of these small tools and provide support for the components connected to them. All of this means that printed circuit board play a crucial role in the success of electronic products. Therefore, they need to meet certain quality standards. Nowadays, most printed circuit board manufacturers follow guidelines established by different quality standards to produce these circuit board.

Because it is manufactured using circuit board printing technology, it is sometimes referred to as a printed circuit board. Printed circuit board is the provider of electrical connections for electronic components and the core of electronic devices. It can be any shape or size, depending on the application of the electronic device.

So, what are the applications of printed circuit board (PCB)?

As the most common substrate/substrate material for PCB, FR-4 is commonly found in many electronic devices and is also the most common form of intelligent manufacturing. FR-4 (PCB) is made of glass fiber and epoxy resin, combined with laminated copper. Some of its main applications include computer graphics cards, motherboard, microprocessor board, FPGAs, CPLDs, hard disk drives, RF, LNA, satellite communication antenna feeders, switching power supplies, Android phones, etc.

With the rapid development of the printed circuit board industry, it plays an important role in medical equipment, industrial equipment, lighting, automotive, and aerospace industries. Below, IPCB will analyze the specific aspects of PCB usage.

Printed Circuit Board (PCB)

1. Application of Printed Circuit Board (PCB) in Consumer Electronics Products

Basically, all electronic products require the use of printed circuit board, but not every appliance requires a circuit board. Simple appliances may not require circuits, such as electric motors. So, which types of consumer electronics products require the use of PCB printed circuit board?

Consumer electronics products that require printed circuit board: These electronic products are designed to save space, make the product lighter, more compact, durable, and achieve good performance. Printed circuit board can meet the requirements of space, performance, and reliability for these products.

Motherboard for household appliances: digital TV amplifiers, mobile phones, washing machines, electronic scales, telephones, LED lights, air conditioners, refrigerators, body audio systems, MP3 players, etc.

The mobile phone motherboard and keyboard are hard printed circuit board. The connecting cable for a slide phone or flip phone is a flexible board. The remote control is usually a carbon film board. The mobile phone board consists of RF circuit, power circuit, audio circuit, and logic circuit from top to bottom.

The heated kettle does not have a circuit board and can be directly connected with a wire bracket. Distributors, electric pots, and induction cookers all have circuit board. The circuit board of an electric fan is commonly used for speed regulation, timing, display, etc., and has no practical impact on the operation of the electric fan.

2. Application of Printed Circuit Board (PCB) in Medical Equipment

The rapid development of medical science is closely related to the rapid development of medical science. Many microbiological and other devices are independent basic PCB, such as pH meters, heartbeat sensors, temperature measurements, electrocardiograms, electroencephalograms, magnetic resonance imaging, X-rays, CT scans, blood pressure monitors, blood glucose level measurement devices, incubators, and other medical equipment.

3. Application of Printed Circuit Board (PCB) in Industrial Equipment

PCB is widely used in manufacturing, especially for those with high-power mechanical equipment driven by high-power circuits. Therefore, a thick copper layer must be pressed onto the top of the PCB, which is different from complex electronic PCB that have a current of up to 100 amperes. This is particularly important in applications such as arc welding, large servo motor drives, lead-acid battery chargers, military, and clothing cotton machines.

4. Application of Printed Circuit Board (PCB) in Lighting

We see LED lights and high-intensity LEDs around us, which can provide high brightness light and are installed on aluminum PCB. Aluminum has the characteristics of absorbing and dissipating heat in air. Therefore, due to their high power, these aluminum circuit board are commonly used for LED light circuits, medium and high-power LED circuits.

5. Application of Printed Circuit Board (PCB) in Aerospace Industry

We use a PCB called Flex PCB, which is the most common reverberation generated by aircraft and car movements, to meet these high vibration forces and make the PCB flexible. Flexible PCB are lightweight, but can withstand high vibrations. Due to its lightweight, it can reduce the total weight of the spacecraft.

Even in narrow spaces, flexible PCB can be adjusted, which is a major advantage of flexible PCB. These flexible PCB are used as connectors and interfaces, and can be assembled even in compact spaces such as behind panels, under instrument panels, etc.

6. The Application of Printed Circuit board (PCB) in the Automotive Industry

Modern cars are increasingly reliant on electronic components. In the past, printed circuit board were actually only used for headlight switches and windshield wipers, while modern automotive electronic devices are used for more purposes. Today's cars utilize the constantly evolving electronic circuit technology by integrating printed circuit board into some new applications. Printed circuit board that process high-frequency signals are typically used in sensor applications, which are now common in automobiles. In fact, radar technology was once downgraded to military vehicles and is now widely used in modern cars to help cars avoid collisions, monitor blind spots, and adjust traffic conditions when the vehicle is under cruise control.

Printed Circuit Board Manufacturer

These advanced systems not only improve road safety but also provide a better driving experience, which is why they are so popular in today's cars. Therefore, manufacturers of these systems must procure and use a larger quantity of advanced high-frequency printed circuit board and related materials. Several common applications of PCB circuit board in automobiles include:

Surrounding monitors: Newer car models are typically designed with robust safety systems to help drivers monitor blind spots and more accurately determine distance. Nowadays, many cars are equipped with full perimeter surveillance systems that can use radar or cameras to measure distance and alert drivers of approaching objects. These systems require high-quality printed circuit board to function properly.

Vehicle control system: The vehicle control system includes an engine management system, fuel regulator, and power supply, which use electronic devices based on printed circuit board (PCB) to monitor and manage resources. In some cases, certain control systems even drive the car for the driver. For example, some cars on the market today offer automatic parallel parking functionality.

Navigation devices: Built in navigation devices are now common in modern vehicles, using GPS computers to help drivers find unfamiliar areas or determine the fastest route to their destination.

Audio and video devices: Many cars on the market today have advanced instrument panels that can connect the vehicle to a radio or passenger's phone or music device. In addition, many family vehicles use passenger movie screens to occupy passengers during longer journeys. All of these devices are controlled using electronic devices based on printed circuit board.

It can be said that all electrical devices use printed circuit board, such as mobile phones, headphones, televisions, fans, cameras, car navigation, instrumentation, power supplies, chargers, and other devices that use electricity in various fields.
