1. Intel has developed software that can perform mechanical, electrical, and thermal analysis of packages in a CAD tool, the PackageDesignAdvisor, which enables the silicon device designer to use the choice of package as his product designA part of the counting process that simulates the impact of chip design on package, and the impact of package on chip design.
2, Rapid Prototyping Packaging (rapid prototyping) is a process that produces simulated samples with rapid prototyping technology to encapsulate products. The advantage of this process is that samples can be quickly manufactured in the development stage of the packaged product, and then tested and modified, making the design more efficient, shortening the product development cycle, and reducing costs.
3, this book focuses on the practical application of Protel99 SE softwareThe core content of electronic circuit CAD technology is explained in detail. The book is divided into 11 chapters designed to help the reader master the software step by step. First of all, in chapter 1, the author makes a comprehensive introduction to the basic structure and operation process of the software with intuitive interface and use environment as the starting point.
2, to change the ordinary mobile phone to wireless charging, usually need to use a wireless charging receiver and corresponding modification tools. Please note, however, that this modification may damage the phone or void the warranty, so it is recommended to proceed only after fully understanding the risks and consequences. Wireless charging technology, which allows users to charge devices without plugging in a cable, has become increasingly popular in recent years. However, not all phones support wireless charging natively.
3, self-made wireless charger 1: external module installation steps Stick the module in the place from the MicroUSB interface comparison. Step Connect the MicroUSB or Lightning port on the module to the phone. Steps If there is double-sided tape on the receiver, you can directly apply itGlue it to the back of the phone. If it doesn't come with it, you have to figure it out yourself. Step to select the most appropriate position, be careful not to let the part of the connection line warped phenomenon.
4. First, make sure your phone supports wireless charging. Connect the wireless charging pad and charging head through the data cable. Generally, you only need to ensure that it is above 10W. Place the phone on the charging pad, with the coil usually located near the camera. There will be a prompt after charging successfully. If your Huawei mobile phone supports wireless charging, place the mobile phone screen facing up in the center of the charger or the position suggested by the manufacturer after the wireless charger is poweredIt's charged.
5, in the phone Settings menu, click [battery]. Click the Charge Settings option. Open the switch on the right side of [wireless reverse charging], and put the phone back to back with the device that needs to be charged. Teach you to convert an ordinary mobile phone that can't be charged wirelessly into one that can be charged wirelessly.
1, gallium nitride fast charge market from concept to mass production for civilian use, only a few yearsA surname; From the mass production of products to the current outbreak of the industry, the interval is less than one year. Only at the beginning of 2020, according to the data at the CES exhibition in the United States, 66 gallium nitride fast charging appliances have been released, showing a blowout development trend.
2, it is also due to these performance advantages, gallium nitride has a wide range of applications in the consumer fast charging source market. Charging head network statistics show that at present, dozens of mainstream power manufacturers have opened up GAN fast charge product lines, and launched hundreds of new GAN fast charge products. Huawei, Xiaomi, OPPO, Meizu, Samsung, ZTE, Nubia, Meizu, realme, Dell, Lenovo and other well-known mobile phone/laptop brands have also entered the game.
3, Xiamen SAN An Integrated Circuit Co., LTD., founded in 2014, is a subsidiary of LED chip manufacturing company SAN An Optoelectronics. Based on gallium nitride and gallium arsenide technology, it is a foundry specializing in compound semiconductor manufacturing, serving the RF, millimeter wave, power electronics and optical markets. With substrate materials, epitaxial growth and chip manufacturing industry integration capabilities.
4. Because the application ecology of gallium nitride is still in the development stage, customers use gallium nitride devices for product designScale, grease and other organic matter quickly fall off and dissolve in the cleaning solution. This cleaning method has the characteristics of high efficiency, environmental protection and non-destructive, and is widely used in various fields.
2, ultrasonic cleaning machine is a kind of equipment that uses high-frequency vibration to produce small bubbles and burst, thereby producing a strong cleaning force in the liquid to clean the items. In terms of glasses cleaning, the use of ultrasonic cleaning machines can more deeply remove dirt and bacteria on the surface of the glasses, while not causing any damage to the glasses.
3, the principle of ultrasonic cleaning machine is mainly to convert the transducer, the sound energy of the power ultrasonic source, and to convertInto mechanical vibration, through the cleaning tank wall so that the cleaning liquid in the tank radiation to the ultrasonic wave. Due to the radiation of ultrasonic waves, the microbubbles in the liquid in the tank can maintain vibration under the action of sound waves. When the sound pressure or sound intensity is pressurized to a certain extent, the bubble will expand rapidly and then suddenly close.
4, the principle of ultrasonic cleaning machine is the high-frequency oscillation signal issued by the ultrasonic generator, which is converted into high-frequency mechanical oscillation by the transducer and transmitted to the medium - cleaning solvent, ultrasonic radiation in the cleaning solution is dense and dense, so that the liquid flows and produces tens of thousands of diameterTiny bubbles of 50-500μm, which exist in a liquid and vibrate under the action of a sound field.
5, super wave cleaning machine is mainly composed of ultrasonic cleaning tank and ultrasonic generator two parts. The ultrasonic cleaning tank is made of high quality stainless steel with strong elasticity and corrosion resistance, and the ultrasonic transducer is installed at the bottom. The ultrasonic generator generates high frequency and high voltage, which is transmitted to the transducer through the cable connection line, and the transducer produces high frequency resonance with the vibration plate, so that the solvent in the cleaning tank is washed by the ultrasonic wave.
6, ultrasonic cleaning machine is an efficient,Convenient home cleaning equipment, can help us quickly clean a variety of difficult to clean items. Whether it is kitchen utensils, personal care items or valuables such as jewelry and glasses, it can be easily restored by ultrasonic cleaning machines.
1, Margo Sound, Logitech, HP and other brands of computer audio is better. Margo Sound Computer Audio Margo Sound is a brand that focuses on audio technology, and its computer audio sound quality is outstanding.
