Thermal material die-cutting actually has such a role
- 2019-03-11-

Thermal cushion is a high performance, filling gap of thermal conductivity materials, mainly used for the transmission of electronic equipment and radiatorThermal material die-cuttingOr the interface between the product housings. It has good viscosity, flexibility, good compression performance and excellent thermal conductivity. In use, it can fully drain the air between the electronic components and the heatsink to achieve full contact. Significant enhancement of heat dissipation effect

OneOverview of thermal conductivity pads

1. As electronic devices continue to integrate more powerful functions into smaller components, temperature control has become one of the important challenges in design, namely, how to effectively eliminate temperature in the case of shrinkage structures and smaller operating spaces. More units of electricity generate more heat.

2, designers have been working hard to improve the CPU speed and processing capacity of various servers. This requires the microprocessor to continuously improve the heat dissipation. But in otherDie-cutting processing plantApplications, such as video game consoles that require higher performance to support HD images, imaging devices and digital applications, also require higher computational performance. As a result, chipmakers are paying more and more attention to heat dissipation materials (thermal pads) and other technologies that can take away too much heat, which have a negative impact on the stability and longevity of components.
3. It is well known that the operating temperature at the junction has a great influence on the durability of the circuit (transistor), while a slight decrease in temperature (10℃-15℃) will increase the life of the equipment by one more times. [1] The lower operating temperature also reduces signal latency, which helps to improve processing speed. In addition, lower temperatures can reduce the device's idle power consumption (power consumption), reducing total power consumption and heat dissipation.
4, the design of the heat conduction pad from the engineering point of view and the irregular surface of the material to match. High-performance thermal conductivity materials are used to eliminate air gaps, thereby improving overall thermal conversion capability and enabling the device to work at lower temperatures

TwoSecondly, the function of the cooling pad

1, heat conduction pad has a certain flexibility, excellent insulation, compressibility and natural surface stickiness. It is specially designed for the use of gap heat transfer design. It can fill the blanks and complete the heat transfer between the heating part and the heat dissipation part. Can be cut arbitrarily to promote automated production and product maintenance.
2, silicone insulation pad thickness from 0.5mm to 5mm,0.5mm to 1mm,1.5mm to 2mm to 5mm range, special requirements can be increased to 15mm. It is specifically designed for the use of Gap heat transfer. The gap is filled to complete the heat transfer from the heating area to the heat dissipation area. At the same time also plays the role of damping adiabatic seal, can meet the social equipment miniaturization, ultra-thin design requirements. 3, this is a very convenient and useful new material. Widely used in electronic and electrical products. With thermal conductivity, insulation, strong shockproof performance, soft surface, with micro-stickiness, easy to operate, can be used for surface and heat sink, shell and other irregular parts between the hot filling effect. Some thermal conductive silicone has fiberglass (or carbon fiber) to increase its mechanical strength.
4, for power supply, LCD/PDP TV, LED lighting, automotive electronics, optoelectronics, notebook computers and other industries. The traditional thermal conductivity material is thermal conductive silicone grease.

ThreeThe following is a simple comparison of thermal pads and thermal conductive silicone grease:

1, thermal conductivity: Thermal conductive silicone pad and thermal conductivity silicone grease thermal conductivity of 1.9-3.0W/M.K and 0.8-3.8W/M.K respectively.
2, Insulation: Due to the addition of metal powder, thermal conductivity of oil insulation is poor. Silicone mats have a good thermal conductivity. The electrical insulation index of 1mm thickness is higher than 4000V.
3, the form: used for condensate heat conduction grease, used for sheet heat conductive silicone pad.
4, the use of methods: heat conduction grease need to be evenly coated (if the size is large, inconvenient to use), easy to cause pollution of the surrounding equipment,Die-cutting of electrically shielded materialsCall the road short circuit and scratch; the heat conduction pad can be cut arbitrarily, the protective film can be directly peeled off. , Small tolerances, clean, saving labor costs.
5, Thickness: As the filling gap of thermal conductive materials, thermal conductive silicone grease is limited, thermal conductive silicone pad thickness from 0.5-10mm, a wider range of applications.
6, Thermal effect: thermal conductivity of the same thermal conductivity grease than soft thermal conductive silicone grease, because the thermal resistance of heat conduction grease is very small. Therefore, in order to achieve the same thermal conductivity, the thermal conductivity of the thermal conductive silicone pad must be higher than that of thermal conductive silicone grease.
7, easy to reinstall, after disassembly re-smear heat conduction grease is not convenient.
8, Price: Thermal conductive silicone grease has been widely used, the price is lower. Thermal conductive silicone mats for thin and small precision electronic products, such as laptops, at slightly higher prices
