1,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.
2, in the range of ravg 0~ 0.08m, the output power increases with the number of coil turnsIncrease and decrease; 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, no matter what electronic products according to the reason, the fewer PCB layers, the worse the electrical performance. On the contrary, the more PCB layers, the better the electrical performance. In electronic products, the more PCB substrate layers, the better. Because of PThe more layers of the CB board, the more solid the foundation of the motherboard, the less interference between signals, to ensure that the electronic components on the motherboard work normally without interference in harsh environments, and the longer the service life.
4, most of the host board is a 4 to 8 layer structure, but technically, the theory can do nearly 100 layers of PCB.
5, if some board guide holes appear on the front of the PCB board, but can not be found on the back, then it must be 6/8 layer board. If the same pilot hole can be found on both the front and back of the PCB board, it is naturally a 4-layer board. But at present many board manufacturersAnother route method is used, that is, only some of the lines are connected, and the buried hole and blind hole technology are used in the route.
1. The steps for disassembling the MG 6 wireless charging board are as follows: First, unscrew the fixing screws at the four corners of the panel and remove the shielding cover plate on the front of the wireless charging board. Shield cover plate back edge exposed copper, black oil insulation in the middle, screen printing PCB-01. The shielding cover plate is made of PCB and has shielding copper foil on it to reduce electromagnetic radiation interference. Inside the aluminum shielded housing are three wireless charging coils that are securedOn the PCBA shield.
2, first, open the central armrest cover of the wireless charging board of Lynk & Co 05. Second, hold the wireless charging board with your hand and lift it upward from an Angle until it is removed from the upper button of the storage box. Finally, pull out the plug on the wireless charging board connector to complete the disassembly of the wireless charging board.
3, push to let go, automatic rebound, if it can not be opened again, it should be the BMW wireless charging board rebound failure, to the 4s shop with a computer overhaul can be. Pull it straight away. There are three clips in the back. Just take them off separately. PCBA is the abbreviation of Printed Circuit Board Assembly, Chinese translation for printed circuit board assembly. PCBA is the process of assembling and welding the electronic components (such as chips, capacitors, resistors, etc.) on the printed circuit board according to the circuit diagram, and physically and electrically connecting the electronic components and the printed circuit board to form a complete circuit system. PCBA is Printed Circu in EnglishShort for it Board Assembly, also called circuit board. That is to say, the PCB empty board through the SMT on the piece, or through the DIP plug-in of the entire process, referred to as PCBA. This is a commonly used writing method in China, while the standard writing method in Europe and the United States is PCBA, with "", which is called the official idiom. PCB refers to an empty circuit board. In this state, the board does not contain any electronic components and looks like green SLATE with dividing lines and Spaces. Therefore, the PCB itself cannot be used for work unless and until the entire assembly is completed. othernessPCBA is also known as the process of welding and assembling electronic components on circuit boards and finished/assembled circuit boards. The finished PCBA is actually used for electronic devices rather than PCBS. PCB is a conductive path pattern based on a non-conductive medium used to support and connect electronic components. By mounting electronic components on the PCB and connecting them, the PCBA forms the structure and function of the circuit. The purpose of PCBA is to assemble different electronic components (such as resistors, capacitors, integrated circuits, etc.) together to achieve a specific function of the circuit board. There are a total of 14 listed companies in wireless charging concept, of which 2 wireless charging concept listed companies are traded on the Shanghai Stock Exchange, and another 12 wireless charging concept listed companies are traded on the Shenzhen Stock Exchange. Below is a list of wireless charging concept stocks. Shunluo Electronics, stock code 002138. Lichun Precision, stock code 002475. Anjie Technology, stock code 002635. Deepsonda A, stock code 000032. Qingdao Haier, stock code 600690. RapoTechnology, stock code 002577. What are the wireless charging concept stocks? Hengdian Dongmagnetic (002056) : Soft magnetic materials supply to Apple wireless charging field iwatch products. Jinsheng Precision (300083) : The company has a wireless charging structure related patents, and is developing wireless charging ceramic battery cover technology. Klik (002782) : On the interactive platform, it said that it has the technical reserve of wireless charging, and will actively carry out the strategic layout and seize the opportunity to enter the market. Apple wireless charging concept stocks are: Hengdian East magnetic (002056Hengdian East Magnetic said on the interactive platform on September 6, 2017, that the company currently provides wireless charging disks to Apple. So, what are the wireless charging concept stocks? The following are several wireless charging concept stocks recognized by the market: SAN 'an Optoelectronics (60070SH) : SAN 'an Optoelectronics is one of the well-known semiconductor lighting and display solution providers in China, and it also has more in-depth research in wireless charging technology.

Mobile phone system failure The mobile phone can not be charged, may be caused by the fault of the mobile phone system, the solution is to shut down the mobile phone directly, and then restart the mobile phone to check whether the mobile phone charging is normal. Mobile phone display charging but not charging may be battery power display problems, non-original charger, poor charger contact, poor charging environment, as follows: battery power display problems, you can directly shut down and restart, equivalent to data refreshThe general power display will return to normal. Verify that the original charger is used. The system of the mobile phone is faulty, thus causing a problem with the battery level display. This problem is the easiest to solve, you can directly shut down and restart, which is equivalent to data refresh, and the general power display will return to normal. The charger is faulty. This failure is the main reason why mobile phones cannot be charged. So how to judge the charger is good or bad. It's actually very simple, try another charger. The reason why the mobile phone is charging but not charged: the data cable is damaged, and the replacement of the data cable can be charged normally. Such asIf you use a non-original charger to charge, replace the charger, you can charge normally. The charging interface has dust, oxidation, pin short circuit, gold finger damage, etc. Clean, wipe or replace the interface, you can return to normal. If you use a Huawei mobile phone, the mobile phone displays charging but still cannot be charged, generally because the current input by the charging device is not enough to offset the power consumed by the mobile phone. The mobile phone shows charging but does not charge it, generally because the current input of the charging device is not enough to offset the electricity consumed by the mobile phone itself.
