What does cpu virtual soldering mean?

This article will explain in detail what cpu virtual soldering refers to. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Cpu virtual welding refers to the CPU welding ball may be due to extrusion, fall and other reasons, resulting in sometimes disconnected, sometimes connected; there are two kinds of virtual welding, one is in the production process, due to improper production process, caused by the unstable state; the other is electrical appliances after long-term use, caused by aging peeling phenomenon.

Virtual soldering means that the CPU solder ball may be disconnected and connected for a variety of reasons (squeeze, drop, etc.).

There are two kinds of virtual welding, one is the unstable state caused by improper production process, and the other is some parts with serious heat after long-term use of electrical appliances, the solder joint at the solder foot is easily caused by aging and peeling phenomenon.

Extended data:

The main causes of virtual welding are:

1. The quality of solder is poor.

2. The reducibility of flux is poor or the dosage is not enough.

3. The surface of the welded joint is not cleaned in advance and the tin plating is not firm.

4. The temperature of the iron tip is too high or too low, and there is an oxide layer on the surface.
