Mi Matter wireless charging mouse pad disassemble Use a crowbar to separate the mouse pad. Divided into aluminum base and mouse pad two parts. The mouse pad corresponds to the wireless charging part Wireless charging film coil above hollowing Wireless film coil , reduce thickness Wireless film coil , maintain consistency. The wireless charging circuit board and coil are attached to the aluminum base plate. Compare the size of a $1 coin. The back of the magnetic separator is insulated with high-temperature tape, the PCB capacitor position is hollowed out to reduce the thickness, and the back has no components. Wireless charging part, the circuit board is more concise.
Compared with the Xiaomi wireless charging treasure 10000mAh currently on sale, the youth version is basically consistent in appearance design, but the new wireless charging film coil Black and white color choice, more young fashion sense. The shell material is changed from metal to plastic, and the function is slightly reduced, so the price is reduced by 20 yuan.
Xiaomi Wireless charging treasure youth version 10000mAh disassembly Xiaomi wireless charging treasure uses an integrated plastic shell, which can only be violently disassembled. Open the shell of the wireless charging surface, inside is the wireless charging coil and thermistor, and there is a shielding cover on the circuit board above. Remove the wireless charging coil to expose the battery. The battery adopts Lishen 7V battery, 10Ah, 10000mAh capacity, the highest charging voltage 2V. The side of the battery is heat sensitiveResistor, real-time detection of battery temperature.
Mo1 5-in-1 Magnetic Wireless Charger T268: A model of exquisite design and efficient compatibility This innovative charger from Mo1 stands out with its 5-in-1 function and intelligent design. This charger is designed for wireless charging of iPhone and Apple Watch dual devices, while equipped with USB-A interface and intimate night light functionDoes line charging technology have requirements for the number of pcb layers
1, for example, for 6-10 layers of memory module PCB design wireless film coil , choose 10/20mil (drilling/welding pad) through the hole is better wireless film coil , for some high-density small size board, You can also try using an 8/18Mil pass hole. Under 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, there is no guarantee that the hole wall can be uniformUniform copper plating) Wireless filling film coil ; For the power supply or ground wire hole, you can consider using a larger size to reduce the 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 techniques (e.g., wire windingCoils, PCB coils) are generally specified to have quality factor values.
3, but wireless charging can not be transmitted as far as WiFi for the time being, and now mature solutions can only achieve wireless charging within a distance of 10mm, generally a distance of about 3~5mm is better, such wireless charging technology uses magnetic induction wireless charging technology. Wireless charging requires a transmitter and a receiver. The transmitter is the wireless charger, the receiver is the mobile phone and so on. There is a coil at the transmitting end and a coil at the receiving end.
