What are the factors that affect the thermal conductivity of thermal conductive silicone pad?   For most electronic product R & D engineers, understanding the characteristics of various thermally conductive materials is their indispensable homework. Only with sufficient knowledge of the materials   What kind of thermal  pad  is good? Considering which aspects of a thermally conductive silicone sheet?   Thermal Conductivity   This is a factor that everyone is most concerned about. Thermal conductivity refers to a 1m thick material with a temperature difference of 1 degree (K, ℃) on the surface of both sides under stable heat transfer conditions. In 1 hour, the heat transferred through an area of 1 square meter is expressed in watts / meter · degree (W / (m · K), where K can be replaced by ℃). The higher the thermal conductivity of the thermal     Density   The porosity of various thermal insulation materials is usually very high. Relatively, their   Hardness selection   When measuri

Why are smart watches the new darling on your wrist?   When it comes to smart wearable devices, the most popular may be smart watches. Currently, smart watches on the market are mainly divided into two categories: health data monitoring and smart experience. Health data monitoring products usually have heart rate, pedometer and calorie consumption monitoring functions, while smart experience watches focus on the application experience on the wrist. For example, the Apple Watch plays a good role as the second screen of the iPhone.   The outstanding performance of the Apple Watch is due to its powerful internal nature. Numerous components are compactly distributed in a small space:   Red: Anhuake AFEM-8087 Orange: OU JQ Yellow: YY MEH ECE (acceleration sensor + gyroscope) Green: AE827 I2033 0836 Blue: STMicroelectronics ST33G1M2 32-bit MCU with ARM SecurCore SC30 The third-party APP for Watch has already exceeded 1000+. As the Apple Watch updates iterative calculations, it becomes more a

Wireless charging technology exponential growth is inseparable from this important component. Wireless charging is a device that uses the principle of electromagnetic induction to charge. By placing a coil on each of the transmitting and receiving ends, the transmitting end coil emits an electromagnetic signal to the outside under the action of electric power, and the receiving end coil receives the electromagnetic signal and converts the electromagnetic signal into Current to achieve wireless charging. The wireless charging technology has broken through the shackles of the traditional charging line, and the usage rate is getting higher and higher. The wireless charger has once become an explosive product in the mobile phone charging industry. However, due to the small size, the operating temperature of the internal electronic components needs to be solved, and the thermal pad provides a heat dissipation solution.   For higher efficiency heat dissipation, the bottom of the wireless cha

What thermal materials are used in drones?   As technology advances with each passing day, the market demands for Take the Dajiang Elf that everyone knows and loves as an example. Let's take a look at how it solves the heat dissipation problem.   The two cores of the drone are the motor and the ESC (ie the electronic governor). The drones are driven by propellers or turbofans. The power to drive them is from the motor, but the speed and power of the motor are controlled by ESC, so The layout of the drone motor and ESC is often relatively compact. If   Thermally gel   There are many types of thermal gel, which one is suitable for drones? Recommended model : WT5921 series The thermal gel is generally packaged in a syringe. The material itself does not contain a solvent, and has the characteristics of high thermal Waermtimo WT5921 series thermal gel is made of silicone, adding thermal conductive filler and bonding material in a certain proportion, and processed by special process. It

Exploring Black Technology-How does VR glasses   Virtual Reality (VR) glasses, or VR headsets, are a new means of human-computer interaction created with the help of computers and the latest sensor technology. VR glasses is a cross-generation product that provides users with an immersive experience in a virtual environment. As panoramic content, content can be raised to a level, and VR will collaborate across fields to promote the development of other industries, such as games, social media,   With the development of VR technology, devices that were originally only concept products have now brought virtual experiences and fun to many gamers. Take VR glasses from a well-known manufacturer as an example, let's explore its true colors together   As somatosensory devices, there are of course accelerometers, gyroscopes, and laser positioning sensors. For 360 ° device tracking, it also has a dedicated Lighthouse infrared receiver. It has 32 sensors in common. These photodiodes absorb inf

How does ipadPro dissipate heat?   The new electronic products come out on market every fall apart from the iPhone series, just is the iPad series. IPad is the intermediate product between smart phones and notebook computers, with more and more powerful functions, chase and play games, and even the drawing function added in the last two years, it has expanded work and entertainment performance.       Let's take a look at the internal structure. How many black technologies are there?     Electronic mask layer of motherboard   The role of this thin layer is not only to protect the motherboard, but also to hide the cable connector, and also to fix the motherboard on the iPad Pro back case. Its motherboard is located in the center of the interior, and the display cable is also connected in the center. The components on the motherboard are relatively dense, with processors, 2 memories, flash memory, gyroscope and accelerometer combination, Wi-Fi modules, controllers, and audio codecs, e

How does the power battery packs of electric vehicle survive the summer? Electric vehicles are becoming more and more popular among the public, and their core power batteries need to be resistant to high temperature, water, and frost. If the electric car does not work, the first time we should consider is the "core" (battery) problem, so in the hot summer, how to deal with the high temperature? How to dissipate heat of the electric car battery? The operating current of the power battery generates a large amount of heat; and the battery pack under a relatively closed environment, it will lead the battery temperature rise. In addition, the outdoor temperature is usually 35+° C. The battery itself generates a large amount of heat. These conditions cause battery heat dissipation become a particularly important problem. Different heat transfer material will lead different effects of heat dissipation, and there exist advantages and disadvantages of both air and liquid cooling. The
