Excessive solder paste can easily cause short circuits and damage to LED beads. The main reason is that solder paste accumulates on the circuit board to form a conductive path, triggering abnormal current. In actual production, the printing volume and distribution uniformity of solder paste must be strictly controlled to avoid LED bead burnout or poor soldering caused by solder paste short circuits.
