The meaning of virtual soldering is that some CPU solder balls may sometimes be disconnected and sometimes reconnected due to various reasons (squeezing, falling, etc.).
There are two types of virtual soldering. One is during the production process, which is caused by improper production technology, causing an unstable state of sometimes and sometimes no connection; the other is when electrical appliances have been used for a long time and some have serious heat. For parts, the solder joints at the solder feet are extremely prone to aging and peeling.
