Printed circuit boards are widely used, involving all aspects of industry, agriculture, aerospace and family life. Only after knowing the purpose of the circuit board products can the circuit board manufacturers understand the quality characteristics required by the PCB, and carry out targeted control .

PCB board is an important part of modern electronic equipment. A typical circuit board is composed of many active and passive components, which are connected by traces on the board. With the subtle development of today's electronic components, engineers can develop large circuits on extremely small boards. Coupled with easy maintenance, low electronic noise and reduced short-circuit risk, this makes the circuit board an advantage over traditional wiring connections. Read on to learn about some of the wider PCB applications in the world today.

Automobile industry

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

Automotive circuit boards have a high degree of reliability and durability. They should withstand continuous vibration and harsh environmental conditions without performance degradation. Before being considered, they must pass strict thermal shock, temperature, humidity, and thermal cycling tests.

Some automotive parts that require printed circuit boards include:

l Engine control system

l Sound system

l Transmission sensor

l Digital display

l Radar

l DC/AC power converter

l ABS

l Air conditioning system

l steering

l LED lighting

l Electronic rearview mirror control

l Dashboard

l Navigation unit

l Engine timing system

LED lighting

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

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

l Medical (lights in medical examinations and surgical tools)

l Computer

l Automobiles (indicators, headlights, brake lights, etc.)

Aerospace parts

Although the electronic equipment used in automotive and aerospace applications are similar in many respects, the aerospace electronic equipment is under rather severe conditions. Aerospace printed circuit boards require components that can withstand extreme temperatures and large amounts of turbulence. They should also be lightweight and anti-oxidant.

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

l lighting

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

l Communication equipment

l Monitoring equipment

Consumer electronics products

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

l Blender and coffee machine in the kitchen

l Smart phone in your pocket

l The computer from which you are reading this information

l TV throughout the room

Medical industry

The latest developments in technology have greatly changed the medical industry. Every day, new and more advanced medical tools are produced and integrated into various processes. This revolution is very beneficial to the PCB industry, because 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 wide-ranging needs of medical device manufacturers. Here are some instruments that require these boards:

l Heart monitor

l ENT diagnostic equipment

l CT scanning system

l Ultrasonic equipment

l Digital cell counting device

l Sphygmomanometer

l Infusion control

l MRI scanning system

l CT scanning system

l Temperature monitor

l Gas analyzer

l Thermometer

l Peristaltic device

l Electrocardiograph

Military equipment

Military-grade printed circuit boards need to be highly durable and reliable under extreme conditions. Due to the vast diversity of military applications, equipment manufacturers also need to use various types of boards.

Circuit boards are required to pass new product introduction, test process design, manufacturability analysis design, and X-ray testing in order to be approved for military use. A rigorous testing process has been carried out to ensure that the design meets high performance requirements and minimizes the risk of failure.

Statistics show that almost one-third of the astronomical military budget is used for electronic equipment. From the perspective of PCB manufacturers, there is a large demand for electronic equipment every year. Typical military uses of printed circuit boards include:

l Temperature sensor

l Cross positioning system

l Automation network

l Network counterintelligence system

l Tower system

l Power

l Power converter

l Automation network
