1, Wireless charging emission circuit board (PCBA) is an electronic component used to achieve wireless charging function. It is one of the core components of the wireless charging system, responsible for converting electrical energy into wireless energy signals and transmission. PCBA usually consists of multiple components, including power supplies, inductors, circuit control chips, filters, and connectors.
2, wireless charging transmission circuit board (PCBA) refers to the electronic components used to achieve wireless charging function, which mainly includes a circuit board (PCB) and various electronic components installed on the circuit board. Together, these components form part of a complete wireless power transmission system, which is responsible for converting electrical energy into wireless signals and transmitting them to receiving devices. Wireless charging technology usually works on the principle of electromagnetic induction or magnetic resonance.
3, PCB (Printed Circuit Board), the Chinese name is called printed circuit board, also known as printed lineThe road board is an important electronic component, the support body of electronic components, and the carrier of electrical connection of electronic components. Because it is produced by electronic printing, it is called a "printed" circuit board.
4, PCBA is the abbreviation of the English Printed Circuit Board Assembly, that is to say, the PCB empty board through the SMT on the piece, and then through the DIP plug-in of the entire process, referred to as PCBA. The difference between PCBA and PCB: From the above introduction, it can be known that PCBA generally refers to a processing process, which can also be understood as a resultProduct circuit board, also on the PCB board processes are completed before PCBA.
5, PCB is short for printed circuit board, is an important electronic component in the electronics industry, is the support body of electronic components, is the carrier of electrical connection of electronic components. PCB factory is widely used in the production of electronic products, its characteristics are as follows: high wiring density, small size, light weight, conducive to the miniaturization of electronic equipment. Reduce wiring and assembly errors, saving equipment maintenance, debugging and inspection time.
6, this shielding cover plate is made of precision PCB board2, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
3, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the mobile phone without wire connection.
4, wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply equipment (charger) to transmit energy to electricityThe device. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
1. AirDesk is a technology desk designed by He, which is inspired by Apple's AirPower wireless charging board. The unique feature of this desk is that users can place their phone anywhere on the desktop for wireless charging. Since the table isTransparent, there will be dynamic animation effects while charging to increase visual interest.
2. He did another thing that made a sensation in the technology circle. He created a desk called Air desk, and wrote a book titled "He | I made a product that Apple gave up......" In the video. After the video was released, He happily mentioned that the top of the hot search list of major platforms, and the video has broken the 9 million mark. The Air desk is actually a high-tech desk made by He, inspired by the Apple Air power wireless charging pad.3. Besides, music songsIn its flagship store on Tmall, LIFT1 is labeled as "the same model as He," and although the desk is not his homemade AirDesk, it has the function of automatically adjusting the height of the desktop. The price range of the product is 2,593 to 5,184 yuan, and some styles are out of stock. After the video was released, Lege's share price rose in response, with a cumulative gain of 151% at the opening, and the company's market value increased by about 500 million yuan to 47.6 billion yuan.
4, everything starts with the "Apple abandoned product AirDesk" that the video caused a great response, and He was also affected"The next Steve Jobs - Steve Jobs!" However, Hobbs was soon tortured by netizens! It reveals that the table is not much technical content in nature, but the video special effects it uses mislead the audience, making people feel good and good Cyberoh.
