28-21 SYGC/S530-XX/XXX

Features

․Package in 12mm tape on 7" diameter reels.

․EIA Std. package.

․Mono-color type.

․Pb-free

․The product itself will remain within RoHS

compliant version.

Descriptions

․The 28-21 SMD taping 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.

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 The LEDs should be used within a year.

2.4 After opening the package, the LEDs should be kept at 30℃ or less and 60%RH or less.

2.5 The LEDs should be used within 168 hours (7 days) after opening the package.

2.6 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.
