Notes

(1)Reflow soldering should not be done more than twice. If more than 24 hours between the two solderings ,

LED will be damaged.

(2)When soldering , do not put stress on the LEDs during heating.

3.1.1 Soldering Iron

(1) When do soldering by hand, keep the temperature of iron below less 300℃ less than 3

seconds.

(2) Soldering by hand should be done only one time.

3.1.2 Repairing

Repairing should not be done after the LEDs have been soldered. When repairing is

unavoidable,a double-head soldering iron should be used (as below figure). It should be

confirmed in advance whether the characteristics of LEDs will or not be damaged by repairing.

3.1.3 Cautions

(1) Components should not be mounted on warped (non coplanar) portion of PCB. After soldering,

do not warp the circuit board.LED

(2) Do not apply mechanical force or excess vibration during the cooling process to normal

temperature after soldering. Do not rapidly cool device after soldering.
