Step 1: We prepare the common tools for tin planting and clean the chip and the corresponding tin planting board hole of the chip.
Step 2: Fix the chip on the tin planting board with label paper, and then fill the solder paste with a blade.
Step 3: Use tweezers to press the tin planting board and heat it with the nozzle of the hot air gun, make sure to master the temperature of the air gun (generally around 400 degrees), the wind (do not exceed 1.5) and the height (2.5cm). When heating, move left and right slightly to heat the tin planting board evenly. And when the solder paste turns into a spherical shape, it means that the solder paste is melted, and then you can stop it.
