◆ Label Form Specification
◆ Precautions In Use
Prepared date：Nov. 2009
1、When soldering, leave the minimum clearance between the bottom of the resin and the soldering point.
2、Maximum allowable soldering conditions are.
3、Contact between molten solder and the resin must be avoided.
4、In soldering, do not put any stress on the lead frame, particularly when heated.
1、When forming leads ,the leads should be bent at a point at least 3mm from the base of epoxy. Lead
forming should be done before soldering.
2、Do not apply any bending stress to the base of the lead. The stress to the base may damage the LEDs
characteristics.
3、When mounting the LEDs onto a printed circuit board ,the holes on the circuit board should be exactly
aligned with the leads of the LEDs.
4、Please avoid conditions which may cause the LED to corrode, tarnish or discolor. This corrosion or
discoloration may cause difficulty during soldering operations. It is recommended that the LEDs be used as
soon as possible.
5、Please avoid rapid transitions in ambient temperature, especially, in high humidity environments.
C、Storage
1、 The LEDs should be stored at 30℃ or less and 70%RH or less after being shipped from Wenrun and
the storage life limits are 3 months . If the LEDs are stored for 3 months or more, they can be stored for a
year in a sealed container with a nitrogen atmosphere and moisture absorbent material.
2、 Please avoid rapid transitions in ambient temperature, especially , in high humidity environments
where condensation can occur.
1、 When necessary, cheaning should occur only with isopropyl alcohol at room temperature for a duration
of no more than one minute . Dry at room temperature before use..
