1, for example, the memory module PC of layer 6-10 wireless charging board B For the design of the wireless charging board , the choice of 10/20mil (drill/pad) through the hole is better wireless charging board , for some high-density small size boards, you can also try to use 8/18Mil through the hole. Under the current technical conditions, it is difficult to use a smaller size through the hole wireless charging plate (when the depth of the hole exceeds 6 times the diameter of the drilling hole, it is impossible to ensure that the hole wall can be uniformly plated with copper); For the power supply or ground wire hole, you can consider using a larger rulerInch to reduce impedance.
2, in the range of ravg 0~ 0.08m, the output power increases first and then decreases with the increase of coil turns; In the range of ravg 0.08~ 0.4m, the output power decreases first and then increases and then decreases with the increase of coil turns. For a fixed operating frequency, the quality factor Q mainly depends on the shape and size of the coil and the material used. Standard coil technologies (such as wire winding coils and PCB coils) generally specify quality factor values.
3, wireless charging PCB, the function is different, the required components are notSame. The required components are wireless charging board : resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
4, wireless charging technology is usually based on electromagnetic induction or magnetic resonance principle. At the transmitting end, AC current passes through the coil to create a changing magnetic field, which can induce a current in another coil close to it (located in the receiving device) to charge the device.
5, electric field coupling technology through wireless transmission of energy, although low energy efficiency, but the most convenient to use. Wireless charging principle andSimilar to the transformer, the system design refers to the transformer structure. Wireless charging products are mainly composed of the receiving end and the transmitting end, the transmitting end includes chips, oscillators, power amplifiers, coils, PCB, passive devices, electronic transformers, structural parts, etc., the receiving end is divided into two parts of the chip and module.
Benefit one: Reduce wear and tear. It is well known that when using wireless charging wireless charging board , you only need to connect the wireless charging board to the power supply first, and then wireless charging will be supportedThe device can be placed on the wireless charging pad. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Benefit 2: high adaptation rate.
Mobile phone wireless charging has the advantages of convenience, flexibility, and protection interface, and the disadvantages are low charging efficiency, slow charging speed, and high cost. Benefits Convenience: Wireless charging of mobile phones eliminates the hassle of using a charging cable. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. spiritActivity: Wireless charging eliminates the dependence on a specific charging cable.
The advantages of wireless charging are: reduce loss, high adaptation rate, the disadvantages are: the distance is too small, only the transition technology wireless charging board; The benefits of wireless charging reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply first, and then place the device that supports wireless charging on the wireless charging board.
The advantages and disadvantages of wireless charging are as follows: Advantages: Wireless charging can reduce the time of wired chargingPlug and unplug the jack, thereby extending the service life of the mobile phone charging interface; Wireless charging technology is suitable for a variety of device types; Wireless charging enables a cleaner, cleaner device appearance, eliminating the clutter of traditional cables.
Advantages and disadvantages of wireless charging of mobile phones: Benefits: Lightning cable wear reduction On the other hand, the popularity of wireless charging of iphones will reduce the use of cables. The wear on the cable will be reduced to almost zero.
Advantages and disadvantages of wireless charging Wireless charging board ! -- With iPhone wireless chargingDoes not affect the charging efficiency of wireless charging. Use the original wireless charger for charging operation, to prevent the non-original charger to supply lithium battery current and voltage instability, affecting the service life of the mobile phone battery. When charging, the charger strip should not be connected to other high-power electrical appliances to prevent the wireless charger from supplying the lithium battery with too little current or voltage.
3, the use of McDonald's wireless charger: find the port suitable for the mobile phone model, plug into the mobile phone charging port; Each table has a circular area with lots of "vinyl" records. Place the mobile phone with the round plastic sheet in the "black film" area of the tableYes. Wireless charging technology (Wireless charging technology; Wireless charge technology, derived from wireless power delivery technology.
4, wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
1, wireless charging base: refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electric energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. [Usage] : Just connect the USB cable and plug it into the socket.
2, Abstract: Charging base is a flat base style charger, it and charging line together to form a wireless charger, canTo charge your phone. The charging base is generally universal, as long as the mobile phone has a built-in wireless charging module, and supports the Qi standard, it can be charged with a wireless charger. When using the charging base to charge, it also needs to be noted that the charging base has a certain induction distance, and the thickness of the phone case may not be able to charge. 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, will handThe standard charger and data cable are connected to the wireless charger, and then put the mobile phone directly (vertically) or horizontally in the center position of the wireless charger base, wireless charging can be achieved, the indicator light will have a breathing effect, 5 seconds later, plug and play, convenient and quick.
