Today to share the knowledge of wireless circuit board, which will also explain the principle of wireless charging board, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>1, the manufacturer is different umt motherboard: The manufacturer of umt motherboard is Hong Kong Oriental Line Limited. opc motherboard: The manufacturer of opc motherboard is Taiwan Xinxing Electronics Co., LTD. umt boards: umt boards do not easily break cables. opc motherboard: opc motherboard is easy to break the board. Wireless chargingDifferent umt motherboards: umt motherboards support wireless charging.
2, umt motherboard and opc motherboard are one of the PCB suppliers for iphone. PCB (Printed Circuit Board), the Chinese name is called printed circuit board, also known as printed circuit board, is an important electronic part, is the support body of electronic components, is the carrier of electrical connection of electronic components. Because it is produced by electronic printing, it is called a "printed" circuit board. As a support body for electronic components, its importance is self-evident.
3, 3, OPC(Oriental Printed Circuits,) Oriental Line Co., LTD., Hong Kong Meiwei Group. Founded in 1985 and headquartered in Hong Kong, our main products are high-end printed circuit boards, as well as semi-cured sheets and copper-covered panels for the production of advanced circuit boards. UMT Taiwan Xinxing Electronics Co., LTD., founded in 1990 and headquartered in Guishan Industrial Zone, Taoyuan County, Taiwan Province, is a world leader in printed circuit boards.
4, first of all, it is not recommended to expand the model within the warranty, because it will lose the warranty, and it is generally recommended to expand the warrantyElectrical network copper film for connecting component pins.
One wireless remote control switch wiring figure: 12V power supply, the output generally has a relay, the device to be controlled is connected to the common contact of the relay and the normally open contact, and the remote control transmitter can control the receiver to hear the relay sound. Wireless remote control refers to the realization of non-contact remote control of the controlled target, which is widely used in industrial control, aerospace and home appliances.
The first switch remote control configuration: press the manual control key on the first remote control switch, and let go after the load lamp is lit. Press the manual button for another 3 seconds or soDo not put, until the load lamp from off to light, and then let go, at this time the remote control switch into the learning state, press any key on the remote control, emit the control signal; After learning successfully, the load lamp will turn on to off. < / p > < p > lamps and lanterns of wireless remote control switch wireless remote control switch is using radio frequency identification (Radiofrequencyidentification) technology, wireless remote control of all kinds of lamps and lanterns, doors, curtain and so on household articles for use of a new type of intelligent switch, can control of the indoor lamps and lanterns of one or more, This product is based on international electrical practice and adopts the most advanced at home and abroadThe electronic circuit design, stable and reliable performance.
General wireless remote control switch code method is roughly the same, the following is the Jinhongyuan submersible pump remote control code method, hope to be able to do a reference for you, you can use the following steps to code.
1, Millet vertical wireless charger with its innovative design and practical functions, become a new choice for charging. This charger was released on November 11During the crowdfunding period, it was launched at a preferential price of 79 yuan, and the retail price was 99 yuan, which was cost-effective.
2, millet 80 watt wireless charging seat with a unique surfing sail shape, by a large triangular column and a small triangular column. The large column is used for shelving the mobile phone, and the vertical structure and double coil design can be charged at will whether it is horizontal or vertical. The bottom design has a large area of heat dissipation grille, metal packaging, convenient heat dissipation. The small column acts as a supporting heat dissipation effect, and the curved air duct is used for efficient heat dissipation.
3, vertical wireless charger recommended the old seven machine no bogey Model 3 (Double coil without fan) 148 yuan to see the name of the old seven began to suspect that there will be a called model S? There is! However, the price is higher at 188 yuan, the charging speed is almost the same as this one, and I think it is not as good as the Model 3, you can see the introduction of the old seven, and personally recommend the cheaper machine Wuji Model 3.
4, Nergin wireless charger easy to use this vertical wireless charger features two colors - coral powder and plum green plus cute appearance! It is so cute that the old man's young heart is broken! Cat-like design, simple and cute, with pink and freshColor, teach you a second to please the girl's heart! Double coil no blind spot, vertical charging is more convenient.
5, vertical design, stable placement. 60 degree elevation vertical design 1, charging and playing machine two mistakes. The bottom card slot is designed with non-slip foot pads to firmly place the mobile phone, and watch the movie more at ease. The high-gloss glass panel is integrated into the pure white simple body, and the appearance is smart and charming at first sight. Fast, fast charge. Support up to 50 W power 2, set a new Huawei wireless fast charge record.
6, can. The iPhone11 supports Qi wireless charging, and its charging power is 5W. Qi wireless charging, refers toThe use of Qi wireless charging standard protocol, wireless charging for mobile phones. This charging method is based on electromagnetic induction mode for mobile phones, digital cameras, handheld playback devices or other low-power devices.
For example, for the 6-10 layer memory module PCB design, it is better to choose 10/20mil (drill/pad) through the hole, and for some high-density small-size boards, you can also try to use 8/18MilThrough the hole. Under the current technical conditions, it is difficult to use a smaller size of the hole (when the hole depth exceeds 6 times the diameter of the 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 size to reduce the impedance.
Control chip: manages the entire wireless charging process, including voltage regulation, power control, communication and other functions. Power amplifier (PA) : Increases signal strength in order to transmit energy efficiently. Oscillators and modulators: Generate high-frequency AC signals for wireless transmission. Coil: Used to generate or receive electromagnetic fields, is the switch of wireless chargingThe key part.
In the range of ravg 0~0.08 m, 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.
