(6) Soldering Conditions
· The LEDs can be soldered in place using the reflow soldering method.
· Recommended soldering conditions
[Temperature-profile (Surface of circuit board) ]
2.5 ~ 5°C / sec.
[Recommended soldering pad design]
· Occasionally there is a brightness decrease caused by the influence of heat or ambient atmosphere
· Repairing should not be done after the LEDs have been soldered.
· Reflow soldering should not be done more than two times.
· Cathode 2 is to be soldered.
· When soldering, do not put stress on the LEDs during heating.
· After soldering, do not warp the circuit board.
