2.5 ~ 5°C / sec.
· The LEDs can be soldered in place using the reflow soldering method.
· Recommended soldering conditions
· Occasionally there is a brightness decrease caused by the influence of heat or ambient atmosphere
· The encapsulated material of the LEDs is silicone. Therefore the LEDs have a soft surface on the
· Repairing should not be done after the LEDs have been soldered.
· Reflow soldering should not be done more than two times.
· When soldering, do not put stress on the LEDs during heating.
· After soldering, do not warp the circuit board.
· It is recommended that isopropyl alcohol be used as a solvent for cleaning the LEDs.
· Do not clean the LEDs by the ultrasonic.

a double-head soldering iron should be used.
characteristics of the LEDs will or will not be damaged by repairing.
other solvents, it should be confirmed beforehand whether the solvents will dissolve the package and the
resin or not.
cleaning on the LEDs depends on factors such as ultrasonic power and the assembled condition.
Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will occur.
