What causes the phenomenon of a monument being erected after LED solder paste soldering?

In useLEDSolder pasteDuring the process, due to improper operation or other reasons, the phenomenon of a monument being erected after welding may occur. What causes this situation to occur? Today, the solder paste manufacturer will explain:

1During the printing process, the solder paste was not brushed evenly, resulting in one side being thinner and the other thicker. After heating, the tensile forces on both sides were different, causing one side to miss the solder and the other side to lift up and stand as a monument.

2Oxidation of electronic components, poor solder paste effect, uneven heating at both ends, resulting in the appearance of the monument.

3,SMTThe patch is offset, resulting in uneven heating.

4During reflow soldering, the furnace temperature was not set properly, with one side having a low temperature and the other side having a high temperature.

5The solder paste dried up after being left for too long, and its activity declined, resulting in the appearance of a monument.

Everything is clearly knownLEDThe reason for setting up a monument with solder paste can be quickly resolved through corresponding adjustments.
