This article to talk about fpc wireless charging design, as well as fastcharger wireless charger price corresponding knowledge points, I hope to help you, do not forget to collect the site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, How does wireless charging work?
1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
2, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the connection to the terminal device that needs to be charged without the traditional charging power cordThe charger on the charger, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. 3, 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.
4, the principle of wireless charging technology is "magnetic electricity", simply put, it is installed on the charging device and mobile phone equipmentThe two "magnetic devices" sense each other and form an electric current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
5, there is no strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
6, generally seenWireless charging, using the "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect."
Wireless charging methods include electromagnetic induction,Magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
Wireless charging transmitter input DC Voltage (DC Voltage). The DC Voltage passes through the power bridge, producing an AC Voltage at SW1 and SW2, which is actually a square wave. Square wave loading inAn AC Current is generated at both ends of the LC Tank. An alternating current passes through the coil to generate a magnetic field. The receiving coil senses this magnetic field and generates an AC Current in the receiving LC Tank. According to officials of the Wuhan Construction Bureau, a total of 60 such wireless charging street lights have been installed on Jianghan Road in Wuhan, each street lamp has two wireless charging locations, and it is still high-power wireless charging, many experienced citizens said that it is not bad, it is very useful, charging on the roadside is also very convenient, of course, be careful of mobile phones being stolen.
Simply put, the mobile phone can be charged through the wireless charger, and then through the wireless reverse charging, the mobile phone as a power source, to another device that can support wireless charging technology for wireless charging, but the disadvantage is that the charging power is relatively small. Wireless charging technology originated from radio energy transmission technology, which is divided into high-power wireless charging and low-power wireless charging.
Wireless charging is mainly based on the Faraday electromagnetic induction principle, which means that the charger and the electrical device are directly connected without wires, but transfer energy through the magnetic field. Wireless charging can be divided into low-power wireless charging and high-power wireless charging two waysSmall power wireless charging often uses electromagnetic induction, such as charging mobile phones.

Electromagnetic induction type wireless charging, when the power supply of the current through the coil (wirelessThe charger's power supply coil) will generate a magnetic field, and other unenergized coils (the phone's receiving coil) will generate current near the magnetic field to charge the phone. As shown below.

Then we need to know what problems will occur in the middle of production and how to solve them.
Learning difficulty: Learning to repair circuit board engineers require a certain amount of learning and practice, the difficulty of which varies from person to person. For some people who are interested in electronic technology and have a certain foundation, it may be relatively easy. But for people without relevant knowledge and experience, it can be more difficult to learn.
For people with basic maintenance circuit board engineers can not learn, for people without basic maintenance circuit board engineers are more difficult to learn, because circuit board maintenance engineers must be able to accurately detect the fault of the circuit board, and professional maintenance technicians.
Are you talking about engineering or technology? Engineering generally requires familiarity with CAD, CAM, and circuit knowledge.
This will be of great help in your future FPC design. In addition, it is best to find a good FPC company, but the current FPC design work is not easy to find, and the salary is not high. If you decide to enter the FPC industry for the high salary, I advise you to quit early, FPC engineers in the first few years of employment will not be paid too much, and there is little experience to draw on.
Difficult. According to a query on Sohu.com,
