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