mechanical ground which prevents mechanical stress
due to lead cutting from traveling into Led package.
This is highly recommended for hand solder opera-
tion, as the excess lead length also acts as small heat
sink.

avoidable circumstances such as rework. The closest

source (soldering iron’s tip) to the body is 1.59mm.
Soldering the Led using soldering iron tip closer than
1.59mm might damage the Led.

• Recommended PC board plated through holes (PTH)
• Over-sizing the PTH can lead to twisted Led after
different heat mass (heat capacity). This might cause a change in
temperature experienced by the board if same wave soldering
setting is used. So, it is recommended to re-calibrate the soldering
profile again before loading a new type of PCB.
Led die with single wire bond as shown below. Customer is advised
to take extra precaution during wave soldering to ensure that the
maximum wave temperature does not exceed 250°C and the solder
contact time does not exceeding 3sec. Over-stressing the Led
during soldering process might cause premature failure to the Led
due to delamination.
Note: electrical connection between bottom surface of Led die and
the lead frame is achieved through conductive paste.
wave soldering should be loosely fitted and should
not apply weight or force on Led. Non metal mate-
rial is recommended as it will absorb less heat during
wave soldering process.
mechanical stress. Therefore, PCB must allowed to
cool down to room temperature prior to handling,
which includes removal of alignment fixture or pallet.
other surface mount components, it is recommend-
ed that surface mount components be soldered on
the top side of the PCB. If surface mount need to be
on the bottom side, these components should be sol-
dered using reflow soldering prior to insertion the TH
