LED screens Wave Soldering
The manufacturing technique of wave soldering is very important in the led display production process. Either the too high temperature, or the unstable temperature of the wave soldering will directly damage the LEDs, or cause the hidden quality problem, especially for the small size LEDs such as 3mm round or oval LEDs.
To accomplish the manufacturing technique well, we need to ensure 2 factors well done: the temperature and time.
1. The temperature. The suggested preheating temperature would be 100℃±5℃, and not exceed 120℃. The preheating temperaturing should rise stably, and the soldering temperature is 245℃±5℃.
2. The time. The soldering time should not exceed 3 seconds.
Moreover, it is strictly forbidden that vibrate the LED before its cooling down to normal temperature status, because it is possible to make the soldering point loose, and arouse the problem of "missing welding".
The practical process is far more complex than what's written in a tutorial because any led display manufacturing process would require the actual experience of years. A good led display manufacturer must has experienced a lot of failures during it's trial period in labs. With learning from those lessons, the engineers would know how to produce the high quality led displays.
