Nowadays, integrated circuits and microelectronics technologies are developing rapidly, and many chip components are gradually shrinking. As product design and development pay more and more attention to the possible impact of temperature on product quality, when designing the entire electrical product system, it is often based on actual conditions. The design of heat dissipation components is carried out in the situation.

Components such as heat sinks, heat dissipation holes, fans, etc., need to be selected and matched by understanding the distribution of their temperature fields.

Through the detection of the above parts by the infrared thermal imaging cameras, you can have a comprehensive understanding of the design and make appropriate improvements. The following is a specific introduction to the application and advantages of thermal imaging cameras in the electronics industry.

When inspecting products, in addition to conventional testing methods, thermal imaging cameras can also be used to detect circuit boards, and through the different temperature points displayed, the current, voltage, and other conditions of the components can be understood. In some maintenance situations, such as quick maintenance tools for circuit boards, thermal imaging cameras can often quickly locate the short-circuit points in the board for further processing without the need for circuit diagrams.

Many thermal engineers will complain that the existing methods are difficult to support them to perform a detailed and comprehensive temperature field description, such as PCB temperature testing, the board surface temperature, the existing methods bring many inconveniences to engineers, such as the circuit board is powered off, the number of patches is not enough, and the operation is complicated.

However, with the infrared thermal imaging cameras, there is no need to touch, no need to cut off the power, and the image you need can be captured with a light touch. At the same time, infrared analysis software can be used for detailed thermal analysis.

The above are all attempts by the electronics industry to detect thermal imaging cameras in the electronics industry. The following introduces the related applications of infrared thermal imaging cameras in LED, an electronic industry with unlimited development prospects.

In the process of LED production and use, the actual life of the LED is inversely proportional to its operating temperature. This is mainly due to the extremely poor photoelectric conversion efficiency of LEDs. Only about 15% to 20% of the electrical energy is converted into light output, and the rest is converted into heat energy.

Therefore, when a large number of high-power LEDs are used in a module, it is applied to high-brightness. During the operation, this extremely poor conversion efficiency will cause a big problem in heat dissipation treatment.

In terms of product heat dissipation and quality testing, thermal imaging cameras play a huge role. It can be applied not only in the research and development process of LEDs but also in product quality management.

(1) LED module drive circuit

In the development of LED products, engineers are required to design a part of the drive circuit, such as a rectifier circuit module. Using a thermal imaging camera, engineers can quickly and easily find the temperature abnormality on the circuit, which is convenient for perfecting the circuit design.

(2) LED light source semiconductor chip heats up

Using a thermal imaging camera, engineers can analyze the temperature of the chip during operation and the temperature distribution based on the obtained infrared heat map of the semiconductor chip of the light source. On this basis, the purpose of improving the lives of LED products can be achieved.

(3) Semiconductor lighting: uniformity of blown bulbs

Through the thermal imaging cameras to capture the process of glass blowing on the production line, parameter correction and improvement of the pinch process can effectively increase the product yield and reduce the cost.

(4) Temperature management before LED inspection chip packaging

Detecting the temperature before the LED chip is packaged can avoid the abnormal temperature of the chip after the package, and reduce the rejection rate.

The characteristics of infrared thermal imaging cameras in the electronics industry

(1) It can be monitored at any time, with no contact, no power failure, no sampling, no disassembly.

(2) Fast scanning and imaging can be realized, the image display is fast, sensitive, vivid, and intuitive, with high monitoring efficiency and low labor intensity.

(3) Passive detection is adopted, which does not affect the working status of the target circuit board, which is simple and convenient.

(4) It is convenient for computer analysis and easy to realize intelligent management.

(5) Infrared detection is conducive to realizing the state management of electronic circuit integration.

Infrared online monitoring does not require detailed data maps of components. The inspectors not only do not need to have strong professional skills, nor do they need to conduct an in-depth analysis of the circuit, they can quickly and accurately determine the faulty components or circuit loops. According to the established infrared fault standards, the hidden faults can be diagnosed in time, which can effectively avoid the sudden faults of electronic equipment.
