(3) Hand Soldering conditions
Do not exceed 4 seconds at maximum 315ºC under soldering iron.
(4) The encapsulated material of the LEDs is silicone.
Precautions should be taken to avoid the strong pressure on the encapsulated part.
So when using the chip mounter,
the picking up nozzle that does not affect the silicone resign should be used.
