For example, for the design of 6-10 layers of memory module PCB, it is better to choose 10/20mil (drill/pad) through holes, and for some high-density small-size boards, you can also try to use 8/18Mil through holes. 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.
is 0 in ravgIn the range of ~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.
Wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
The iPhoneX and iPhone8/8 plus support fast charging and wireless charging. But the above accessories are not randomly attached, need to buy separately. The wireless base is more than one hundred, low charging efficiency, slow charging speed, but it is convenient to insert the data cable. Fast charging is to buy another 29W charger and USB-C data cable, charging faster, but a set of accessories to add upIt's nearly seven hundred dollars. It's not a good deal.
is two different devices, want to fast charge must spend 388 yuan to buy 29W USB-C charging head, and then spend 188 yuan to buy USB-C/Lightning data cable, a total of 576 yuan. The wireless charging base costs 498RMB.
That for me Huaqiang North is a piece of wireless charging base of dozens of dollars, but Apple's offer is really amazing. Because the purchase of the iPhone8 will not be given a wireless charger but will be purchased separately, media reports say that the wireless charger may be sold for $1,899 (RMB 1288 yuan).
Apple wireless charging is not fast charging. Wireless charging itself is not efficient, when using Apple's original wireless charger normal charging, it is also easy to make the Apple phone heat, if coupled with fast charging, the phone will generate more heat, so there is a certain risk, so, Apple phone generally do not fast charge, do not use wireless charging, wireless charging is just a empty function, not very practical.
