(5) Soldering Conditions
· The LEDs can be soldered in place using the reflow soldering method.
· Recommended soldering conditions
· Repairing should not be done after the LEDs have been soldered.
· Reflow soldering should not be done more than two times.
· Before soldering every time, make baking to units. By manual soldering, there is possibility of crack
· When soldering, do not put stress on the LEDs during heating.
· After soldering, do not warp the circuit board.
· Handle the devices only after temperature is cooled down.
