Matters needing attention when welding SMT chips
a. Generally, the time of the whole welding operation of the solder joint is controlled within 2~3s.
b. The time between each welding step is very important to ensure the welding quality, and it needs to be mastered gradually through practical operation.
c. After the welding operation is completed, the position of the welded part cannot be changed until the solder paste is completely solidified.
d. The electric soldering iron should generally be an internal heating type (20~35W) or a constant temperature type, and the temperature should not exceed 300℃. Generally, a small conical soldering iron tip is used.
