Xiaomi 11 burning WiFi this problem is actually caused by CPU virtual welding, this problem appeared more in April, it is estimated that the summer originally this generation of Snapdragon 888 heat on the big temperature control is not so radical, if charging while playing games, there may be this problem.
The virtual welding problem mainly appears in the millet 11, the two mobile phones released after the millet 11Pro\/Ultra due to the upgrade of heat dissipation, coupled with the pre-installed system has temperature control, there is no Pro\/Ultra appeared in a wide range. These two days the topic of burning WiFi appeared again, it is estimated that the MIX4 release caused, anyway, the problem does exist.
Millet 11cpu will have a virtual welding problem, according to the maintenance \"test, the reason why WiFi can not be used is not burning WiFi, nor is the motherboard burned out;
But because the Mi 11 on the Yanlong 888 processor heat caused by the CPU welding.
The so-called virtual welding means that there is only a small amount of tin welding column at the solder joint, resulting in poor contact and breaking.
There are many pins on the CPU, and they all perform their own duties: some pins are responsible for communication, and some are responsible for memory;
Some pins are used for the next generation of CPU design when dragging, and some are purely superfluous decoration.
It's not a weld, it's a weld that's not that strong
It is interesting that after the release of millet 11, the third-party dismantling evaluation of the arrangement has greatly praised the chip sealing glue.
