With the development of the new energy automobile industry, new energy vehicles are constantly emerging, and automobile intelligence has also developed rapidly, and technology companies have deployed automotive electronics. A set-top box refers to a kind of information equipment used to enhance or expand the functions of a TV. Because people usually put it on top of the TV, it is also called a set-top box or a set-top box. As of November 2008, there are analog and digital set-top boxes, and now people generally refer to digital set-top boxes. A digital TV set-top box is a conversion device that converts digital TV signals into analog signals, and can provide TV users with high-quality TV programs.
The digital set-top box is not only a user terminal, but also a network terminal. It can turn analog TV from passive reception of analog TV to interactive digital TV (such as video on demand, etc.), and can connect to the Internet, allowing users to enjoy TV, data, and language And other comprehensive information services. At present, some people think that the set-top box is used to make the TV go online, which is a misunderstanding in understanding. In fact, the digital set-top box is one of the members of the broadband integrated information network before the popularization of digital TV. With the development of digital technology, multimedia technology and network technology, the built-in and overall cost of digital set-top boxes will be reduced, allowing most users to realize multiple services such as entertainment and Internet access on ordinary analog TVs.

The main heating elements of set-top box products:
★Chip, PCB board with pin angle, tuner module (receiving signal)

Application environment of thermal conductive materials:

1. Between the chip and the heat sink


Aoqi thermal products have mature thermal management material solutions in new energy vehicle battery packs, motor controllers (MCU), body electronic controls (ECU), car chargers, chassis control, car entertainment and other systems, which can provide heat dissipation /Heat/heat conduction/heat insulation and other series of product supporting solutions to assist customers in achieving the safety and reliability of automotive electronic products.


2. Between the PCB board and the bottom case

In addition to using the thermally conductive silicone sheet on ICs with high heat generation, a thermally conductive silicone sheet is also attached to the IC's corresponding PCB board (some PCB boards have pins underneath) to directly contact the shell. At the same time, the pins are inserted in the thermally conductive silicone sheet, so that the heat is more easily discharged.

3. Between the tuner and the shell

The high-frequency head on the set-top box module (mainly plays a role in receiving signals), and the high-frequency head will also emit heat when the function and performance of the set-top box are extremely high. If the temperature is too high, it will affect the signal of the set-top box and cause signal interference. Therefore, it is also necessary to use the thermal pad and the shell for heat dissipation.

Thermal conductive materials used on the set-top box:
★ Thermally conductive silicone sheet, thermally conductive double-sided tape, thermally conductive silicone grease, thermally conductive adhesive
