11. Precaution for use

• Before opening the package

a. Avoid the absorption of moisture, we recommended to store the LEDs in a dry

box(or desiccator) with a desiccant . Otherwise, store them in the following environment:

Temperature : 5℃~30℃ Humidity : 50% max.

b. The products should be used in 3 months. It is recommended that the LEDs be used as

soon as possible.

• After opening the package

a. Soldering should be done right after opening the package(within 24Hrs).

b. Keeping of a fraction

- Sealing

- Temperature : 5 ~ 40℃, Humidity : less than 30%

c. If the package has been opened more than 1week or the color of desiccant changes,

Components should be dried for 10-12hr at 60±5℃

• Any mechanical force or any excess vibration shall not be accepted to apply during cooling

process to normal temp. after soldering.

• Avoid quick cooling

• Lead frames are silver plated SPCC. The silver plate surface may be affected by

environments which contains corrosive substances. Please avoid conditions which may cause

the LEDs to corrode, tarnish or discolor.

2) Lead Forming

• When the lead forming is required before soldering , care must be taken to avoid any bending

and mechanical stress. The stress to the base may damage the LEDs.

• When mounting the LEDs onto a PCB, the holes on the circuit board should be exactly

aligned with the leads of the LEDs.

• It is recommended that tooling made to precisely form and cut the leads to length rather than

rely on hand operating.
