therefore,
lease concern before desi

※The
roduct has ado
ted the electrode structure that it should
solder with back electrode of the
roduct.
Thus,
lease be informed that the sha

In case of carryin
out flow solderin
of surroundin
parts without recommended conditions, please
contact us for inquiries.
・Please set appropriate reflow temperature based on our product usa
e conditions and specification.
・The max for reflowin
is 2 times, please finish the second reflow solderin
and flow solderin

・Compare with N2 reflow, durin
air reflow, because of the heat and surroundin
conditions,
it may cause the discoloration of the resin.

・For our product that has no solder resist, because of its solder amount and solderin
conditions,
one of its specific characteristics is that solder will penetrate into LED. Thus, there's hi
