(5) Soldering Conditions
· The LEDs can be soldered in place using the reflow soldering method.
· Recommended soldering conditions
2.5 ~ 5°C / sec.
· 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.

Although the recommended soldering conditions are specified in the above table, reflow or hand
soldering at the lowest possible temperature is desirable for the LEDs.
A rapid-rate process is not recommended for cooling the LEDs down from the peak temperature.
