* Caution
[1] Reflow soldering should not be done more than one time.
[2] Repairing should not be done after the LEDs have been soldered. When
[3] Die slug is to be soldered.
[4] When soldering, do not put stress on the LEDs during heating.
[5] After soldering, do not warp the circuit board.
[6] Recommend to use a convection type reflow machine with 7 ~ 8 zones.
