Application fields and cases of PCB circuit boards

Printed circuit boards are widely used in industry, agriculture, aerospace, and household life. Only by understanding the purpose of circuit board products can circuit board manufacturers know the quality characteristics required for PCBs and carry out targeted control. PCB is an important component of modern electronic devices. A typical circuit board consists of many active and passive components, which are connected through wiring on the board. With the subtle development of electronic components today, engineers can develop large circuits on extremely small boards. In addition, the ease of maintenance, low electronic noise, and reduced risk of short circuits make circuit boards advantageous in traditional circuit connection methods. Please continue reading to learn about the wider range of PCB applications in the world today.

Automotive industry

Most applications in modern vehicles rely on electronic control to operate correctly. The printed circuit board fixes these components and exquisite sensors together.

Automotive circuit boards have high reliability and durability. They should withstand continuous vibration and harsh environmental conditions without experiencing performance degradation. Before considering, they must undergo rigorous thermal shock, temperature and humidity, and thermal cycling tests.

Some automotive components that require printed circuit boards include:

Engine control system

Sound system

Transmission sensor

Digital display

L radar

DC/AC power converter

l ABS

Air conditioning system

L steering

LED lighting

Electronic rearview mirror control

L Dashboard

Navigation unit

Engine timing system

LED lighting

Due to their relative efficiency and cost-effectiveness, LED lighting is gradually phasing out incandescent bulbs and compact fluorescent lamps. LED bulbs use metal core PCB boards because they generate less heat during use. Compared to standard rigid plates, most manufacturers prefer aluminum because it has excellent heat dissipation and more efficient heat transfer. All aluminum printed circuit boards are composed of three layers - the base layer, insulation layer, and circuit layer. Each tool has different forms of variation, depending on the application that builds them. Typical industry applications of PCB LED include:

Telecommunications (indicators, displays, high-frequency amplifiers, and filtering equipment)

Medical (lights in medical examinations and surgical tools)

Computer

Car (indicator lights, headlights, brake lights, etc.)

Aerospace components

Although electronic devices used in automotive and aerospace applications are similar in many ways, aerospace electronic devices are subjected to quite harsh conditions. Aerospace printed circuit boards require components that can withstand extreme temperatures and large amounts of turbulence. They should also be lightweight and antioxidant.

The specific uses of printed circuit boards in the aerospace industry include but are not limited to:

L Lighting

Power supplies: They are devices used to supply power to satellites, control towers, and a range of other systems.

Communication equipment

Monitoring equipment

consumer electronics

The consumer electronics industry is the favorite market for PCB manufacturers, which is understandable. We live in the era of small tools. Every household has at least one electronic device, and some small tools are steadily entering the basic needs range. Each of these appliances performs a different independent function, but they all run on a printed circuit board:

Blender and coffee machine in the kitchen

Smartphone in pocket

The computer from which you are reading this information

The TV in the entire room

Medical industry

The latest developments in technology have greatly changed the healthcare industry. Every day, new and more advanced medical tools are produced and integrated into various processes. This revolution is very beneficial for the PCB industry, as most of these inventions rely on electronic printed circuit boards for operation.

Today's PCB manufacturers manufacture extremely basic to highly complex circuit boards to meet the diverse needs of medical equipment manufacturers. Here are some instruments that require these boards:

Cardiac monitor

Ear, nose and throat diagnostic equipment

CT scanning system

Ultrasonic equipment

Digital cell counting device

Blood pressure monitor

Infusion control

MRI scanning system

CT scanning system

Temperature monitor

Gas analyzer

L thermometer

Peristaltic device

Electrocardiogram device

military equipment

Military grade printed circuit boards require high durability and reliability under extreme conditions. Due to the diverse military applications, equipment manufacturers also need to use various types of boards.

Request the circuit board to be approved for military use through new product introduction, testing process design, manufacturability analysis design, and X-ray testing. A rigorous testing process was conducted to ensure that the design meets high-performance requirements and minimizes the risk of failure to the greatest extent possible.

Statistics show that almost one-third of the astronomical military budget is used for electronic devices, and from the perspective of PCB manufacturers, the demand for electronic devices is high every year. Typical military applications of printed circuit boards include:

Temperature sensor

Cross positioning system

Automated Network

Network Counterintelligence System

Tower system

Power supply

Power converter

Automated Network

Audio interface application

PCB is used in many places, both flexible and rigid. Our intelligent life is filled with various aspects.
