Common soldering methods can be divided into electric soldering iron soldering, heating platform soldering and reflow soldering soldering, etc.:

A. Soldering with electric soldering irons is the most common, such as making samples and repairs. In order to save costs, most of the existing manufacturers buy electric soldering irons that are unqualified and slightly quality products, most of which are poorly grounded, leaking, and soldering. This is equivalent to forming a loop between the leaking soldering iron tip-the soldered LED-the human body-the earth, which means that it is equal to dozens-hundreds of times the voltage that the lamp bead bears when it is applied to the LED lamp bead LED light board patch. Burn it out. Note: The situation of connecting the electrostatic belt will be more serious, because when the human body is connected to the electrostatic belt, the resistance of the circuit to the ground will be smaller, and the current through the human body to the lamp beads will be greater. This is also what many people say there is static electricity. The belt still has so many lamp beads damaged LED chip processing.

B. Dead lights caused by welding of heating platform. Due to the continuous sample list of lamps, most companies meet the needs of small batches and sample lists. Due to the advantages of low equipment cost, simple structure and operation, heating platform has become the best production tool However, due to the use environment (such as the problem of instability in the temperature where there is a fan), the welding operator’s proficiency and the control of the welding speed have become a major problem of dead lights, and there is also heating Equipment grounding of the platform Tricolor Light Emitting Diode.

　　C, reflow soldering. Generally, this soldering method is the most reliable production method, suitable for mass production and processing. If the operation is not performed properly, it will cause more serious consequences of dead lights, such as unreasonable temperature adjustment, poor machine grounding, etc High-power purple lamp beads.
