Descriptions
The 28-21 SMD LED is much
smaller than leaded components .Thus
enable smaller board size. Higher
packing density. Reduced storage space
and finally smaller equipment to be
obtained.
Besides, light weight makes them
ideal for miniature applications.
Furthermore by automation assembly
machines the accuracy is anticipated.
Applications
Small indicator for indoor applications.
Flat backlight for LCD, switches and symbols.
Indicator and backlight in office equipment.
Indicator and backlight for battery driven
equipment.
Indicator and backlight for audio and video equipment.
Backlighting in dashboards and switches.
Telecommunicationindicator and backlighting in telephone and fax.

Precautions For Use
1. Over-current-proof
Customer must apply resistors for protection , otherwise slight voltage shift will cause big
current change ( Burn out will happen ).
2. Storage
2.1 Do not open moisture proof bag before the products are ready to use.
2.2 Before opening the package: The LEDs should be kept at 30 or less and 90%RH or less.
2.3 After opening the package: The LED's floor life is 1 year under 30 or less and 60% RH or less.
If unused LEDs remain, it should be stored in moisture proof packages.
2.4 If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the
storage time, baking treatment should be performed using the following conditions.
Baking treatment : 60±5 for 24 hours.
3. Soldering Condition
3.1 Pb-free solder temperature profile
3.2 Reflow soldering should not be done more than two times.
3.3 When soldering, do not put stress on the LEDs during heating.
3.4 After soldering, do not warp the circuit board.

4. Soldering Iron
Each terminal is to go to the tip of soldering iron temperature less than 350 for 3 seconds
within once in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and
do soldering of each terminal. Be careful because the damage of the product is often started at the
time of the hand solder.
5.Repairing
Repair should not be done after the LEDs have been soldered. When repairing is
unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed
beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.
