With the changes in the requirements of the times, various types of communication power supply equipment have appeared in various styles to consider different requirements. However, such a phenomenon has increased the number of manufacturers, resulting in incompatibility with the equipment due to the difference from the agreement. . In order to integrate into the development, there are also many communication power supplies that use the so-called standard interface, that is, the universal interface, which improves the compatibility between the devices. It is worth mentioning that the coordination ability of the communication device is also improved. At present, different circuits are available in different places for communication power supplies.
There are three key choices. For small or moderate power, double-ended circuits or half-bridge circuits are generally used. For full power applications, full-bridge conversion circuits are used. Different circuits have their own advantages and disadvantages. In addition to the practicality and different circuits that are often mentioned above, today's communication power supply is also very intelligent, and can carry out diagnosis and simple maintenance on itself to keep the equipment running. Because of this, the status quo of communication power supply is in line with the requirements of the times and society, and is developing efficiently, safely and steadily.
How do I know what to do if the mobile communication circuit board fails?
Failures of mobile phone photo screen
First, let's talk about the problem of surveillance cameras that are more harmful to applications. When the display screen freezes, the flower screen and the picture are not clear, there are generally three reasons;1. The relevant components of the mobile phone communication circuit board are not good; first if the flower screen and the previous monitoring camera have a flower screen phenomenon, you should first distinguish whether the welding of the surveillance camera components is not good. First check whether the welding spot of the camera is false welding, empty welding, or the electroplated tin of the welding spot is not plated well. If it is the same as the above problem, it can be welded again by electric welding.
2. The bulging surveillance camera is extruded due to external force, causing the surveillance camera to deflect. In general, such situations are very rare. The solution is relatively simple, just disassemble and install it again.3. The firmware version is wrong, such problems generally appear on the notebook motherboard. Use the data cable to connect to the computer to update the software.
