Caution

(1) The reflow cycle is limited to max 2 times.

(2) Re-soldering should not be done after the LEDs have been soldered.

If re-soldering is unavoidable, LED`s characteristics should be carefully checked before and after such repair.

(3) Do not put stress on the LEDs during heating.

(4) After reflow, do not warp the circuit board.

(5) After reflow, do not clean PCB by water or solvent.

(6) We recommend on/off(@0.1~1mA)
