The application development trend of thermoelectric coolers in infrared detectors

-

According to the current development status of infrared detectors, combined with the future development trend of thermoelectric cooler technology, the application of semiconductor coolers in infrared detectors mainly develops in the following aspects:

1.Lead-free solder

During the rapid development of science and technology, lead solder is gradually being replaced by lead-free solder. In the actual application process of lead-free solder, it can effectively solve the heavy metal problem of lead in the application process of traditional leaded solder, and reduce the adverse impact on the ecological environment. In recent years, lead-free solders have gradually been used in the manufacture of semiconductor refrigerators, thereby reducing the adverse effects of semiconductor refrigerator manufacturing on the surrounding environment. It is consistent with the requirements of my country's sustainable development strategy. Lead-free solders are being produced, not only Can only be reduced by half The impact of conductor coolers on the ecosystem can also effectively meet the manufacturing process requirements of thermoelectric coolers. In the two manufacturing working planes, multiple welding temperature points are used in accordance with the actual material requirements for production. Lead-free solder is used in the manufacture of semiconductor refrigerators, and can also be applied to alloy materials and ceramics.

2. Integrated infrared detector

In the future development and construction process of semiconductor refrigerators, the weight and volume will gradually decrease and gradually develop in the direction of miniature semiconductors. The volume and weight of the miniature semiconductor cooler are more compact, but the power load it can bear is significantly improved compared with the same volume, and it can be used in large infrared detectors. In this case, infrared detectors will gradually develop towards miniaturization and integration in the future development and construction process. With the help of the advantages of different types of semiconductor coolers in the actual application process, the performance of infrared detector components will be improved.

3.Meet the needs of different temperature points

According to the actual application of the semiconductor cooler in the infrared detector at this stage, the semiconductor cooler can already meet the actual needs of the infrared detector working and running at different temperature points. In the development process of the application of semiconductor coolers in infrared detectors, it is also necessary to select the type of semiconductor coolers for the application according to the operating time of the infrared detectors in different bands, so as to meet the requirements of infrared detectors in different working bands. However, it is important to note that if the semiconductor cooler wants to be used in infrared detectors in multiple working bands, it must have a variety of types of automatic temperature control systems and infrared detectors for its choice. The semiconductor cooler is used in infrared detectors. The internal application provides guarantees on the control system and materials.

The introduction and application of audio amplifier

-
Image
With the continuous changes in the audio market demand, the audio amplifier design structure has made great progress. When selecting the best audio amplifier IC for a specific application, it is important to have a full understanding of the types of audio amplifiers available and their characteristics. The audio amplifier increases the amplitude of a small signal to a useful level while retaining the details of the small signal, which is called linearity. The better the linearity of the amplifier, the more true the output signal can represent the input signal. As the audio market's requirements for amplifier performance continue to change, audio amplifier circuit structures have made great progress. Therefore, the designer must understand the available audio amplifiers and their characteristics. This is the only way to ensure that the best audio amplifier is selected. In this article, we introduce the most important features of the various audio amplifiers available today: Class A,...

Precautions when using the force sensor

-
Image
Although the force sensor has the characteristics of solidarity and durability, there are still some problems we should pay attention to when it is used.  1. protecting the force sensor from contamination caused by the external environment We should try to set up some "baffles" around the force sensor, and even cover the force sensor with a thin metal plate. This can prevent debris from contaminating the force sensor and certain movable parts, and this "contamination" often affects the weighing accuracy. 2. the connection of the shielding wire and the grounding point should be reasonable All wires leading to or from the display circuit should adopt shielding cables. The connection and grounding point of the shielded wire should be reasonable. If it is not grounded through the mechanical frame, it is grounded externally. 3. avoiding strong heat radiation The force sensor should use hinged copper wires (cross-sectional area of ​​about  50mm 2 ) to form an electrical b...

IRF640 vs IRF740: What is the difference?

-
Image
MOSFET Explained / Description IRF740 is a high voltage N channel MOSFET, the transistor is basically designed for high voltage and high-speed switching applications. The max load voltage this transistor can drive is up to 400V with a maximum load current of 10A. The maximum current in pulse mode is 40A and the on-resistance or (RDS) is 0.55 ohms. The max drain to source voltage of 400V makes it ideal to drive a variety of high voltage loads in electronic circuits.   IRF640 is an N Channel MOSFET designed for high-speed switching purposes. This high-speed switching capability can be very useful in applications where switching speed is crucial, for example in a UPS circuit or in any other application where the user wants to change the load input power from one source to another. The transistor is capable of driving a load of up to 18A and the voltage can be up to 200V with the minimum saturation voltage of only 2V to 4v at its gate. The pulsed drain current is 72A means this MOSFET ...
