What solder paste do I need to solder a mobile phone motherboard?

Soldering mobile phone motherboards requires the selection of solder paste suitable for high-density, fine solder joints, and the following are key factors and recommendations:

Reliability of BGA solder joints under mechanical and thermal stresses

BGA (Ball Grid Array Package) is a common integrated circuit packaging technology which has the advantages of large contact area and high signal transmission efficiency. However, BGA solder joints are located at the bottom of the device and are not easy to detect and maintain.

Device failure due to SMT wick effect

The wick effect, also known as the creeping tin effect, is an inherent characteristic of solder in the PCB soldering mechanism: "solder always flows from low temperature to high temperature", which means that the nature of solder is to go where the temperature is high.

What causes a lot of solder paste residue?

The problem of solder paste residue is usually caused by a combination of process parameters, material properties, equipment condition and environmental control.The following combines industry practice and the latest research, common causes and solutions for systematic sorting and supplement:
