Solder directly on with soldering iron. Steps: First remove the dirt on the welding surface. Apply the welding oil or rosin soldering iron to the welding spot and then melt the solder to the solder spot Solder wireless charge and stick.
Hot air gun The hot air gun is mainly a tool for welding and removing components by using the hot air blown by the gun core of the heating resistance wire. According to the working principle of the heat gun solder wireless charging , the main part of the heat gun control circuit should include temperature informationNumber amplifier circuit, comparison circuit, thyristor control circuit, sensor, risk control circuit, etc. The heat gun temperature is usually between 100°C and 550°C, with some reaching 760°C.
The welding of mobile phone components belongs to SMT welding (surface mount technology). The main process is to first print solder paste on the plate pad, and then put all components into the corresponding position of the board through the mounting machine, after completion, reflux furnace heating, solder paste melting. Other mobile phone welding tail plug, to prepare things in advance: electric soldering iron is best to adjust the temperature of 320 degrees, horseshoe mouth. Wind gun 330 degrees, strong windSmall according to their own wind gun power, solder wireless charge I use 6 gear.
Welding method: Welding surface treatment of welding parts encountered in manual soldering iron welding is a variety of electronic parts and wires, unless the use of electronic components in the "insurance period" under large-scale production conditions, generally encountered welds often need to be cleaned on the surface, remove rust on the welding surface, oil, dust and other impurities that affect the quality of welding. Simple and easy methods such as mechanical scraping, alcohol and acetone scrubbing are commonly used in manual operation.
Clean: clean the parts to be weldedDust and oil, so that the electric soldering iron head can contact the solder to be welded. Heat welding: Contact the solder joint with the part to be welded for a few seconds with a small amount of solder and rosin. Clean the welding surface: If there is too much solder at the weld, remove the solder on the tip of the iron. If the solder is too little and not smooth, the soldering iron head can be "dipped" in some solder to repair the solder joint.
Finally, pay attention to check whether the welding component is not short circuit welding. bga chip welding: To use the bag chip attachment machine, the use of different machines is different, the attached manual has a detailed description.
solder wireless charging memory module PCB design solder wireless charging , the choice of 10/20mil (drill/pad) through the hole is better, 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 of the hole (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) Solder wireless charging ; For power or groundThe hole of the line can be considered to use 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 Solder wireless charging ; 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 technology (such as wire winding coils, PCB coils) is generally standardizedMust have quality factor value.
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.
4, wireless charging PCB, different functions, the required components are different. The required components are solder wireless charge : resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
5, specifically, Wanan technology shares in the United States wireless charging leading enterprise, Tesla wireless charging supplier Evatran company, to obtain wireless charging core technology; Shuobed magnetic resonance wireless charging technology is the focus of the company's research and development direction, has obtained magnetic resonance wireless charging system utility model patent.
The reasons for the failure of the Apple 15 wireless charging may be as follows: The device is not aligned with the charger. If the device is not properly positioned in the center of the charger,Or there are physical barriers that may cause charging to fail. The charger is not connected to power. Make sure the wireless charger is plugged into the power adapter and connected to the power supply. The power adapter is faulty. If the power adapter fails, it may affect the work of the wireless charger.
Charging dock or charger issues: If you've made sure your device supports wireless charging and you've turned on the option, but still can't use wireless charging, check that the charging dock or charger you're using is compatible and places your iPhone correctly. Make sure the base or charger meets the Qi wireless charging standardAnd ensure that your phone is properly placed on the base so that a wireless charging connection can be established between the phone and the charger.
There is a problem with the charger or charging cable, and there is a problem with the phone battery. Faulty charger or charging cable: Make sure you are using an Apple certified charger and charging cable and check for damage or wear. Mobile phone battery problems: Mobile phone battery has been aging or damaged, will also cause wireless charging can not work properly, the battery needs to be replaced.
Wireless charging accessories damaged, foreign body blocking, etc. Wireless charging accessories damaged: Using an external wireless charger or accessories, there is damage orFaulty. Check that the charger and related devices are working properly to ensure that they are compatible with the Apple 13. Foreign object blocking: In the wireless charging area applicable to the Apple 13, any foreign object placed between the phone and the base, blocking the transmission signal will affect the normal wireless charging.
