periodically check on the soldering profile to ensure the
soldering profile used is always conforming to

cause a change in temperature experienced by the board if
same wave soldering setting is used. So, it is recommended
to recalibrate the soldering profile again before loading a
new type of PCB.

Customer is advised to take extra precaution during wave
soldering to ensure that the maximum wave temperature
is not exceeding 250 C. Overstressing the LED during
soldering process might cause premature failure to the LED
due to delamination.
