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 It is recommended to store the products in the following conditions:
Humidity: 60% R.H. Max.
Temperature : 5℃~30℃(41℉~86℉)
2.2 Shelf life in sealed bag: 12 month at ＜5℃~30℃ and ＜60% R.H. after the package is
00000000000000
Opened, the products should be used within a week or they should be keeping to stored at
0
≦20%R.H. with zip-lock sealed.

3.Baking
It is recommended to baking before soldering when the pack is unsealed after 24hrs. The
Conditions are as followings:
3.1 70±3℃ x(12~24hrs) and ＜5%RH, taped reel type
3.2 100±3℃ x(45min~1hr), bulk type
3.3 130±3℃ x(15~30min), bulk type

LED Usage and Handling Instructions
No.1、soldering：
A、It’s not better to be manual soldering.
B、Reflow soldering：
1、Soldering according to the following temperature chart is highly recommended
0000000000000000000000000000000000000000000000000000000
2、Soldering paste
Use soldering paste with the melting point at 230℃ is recommended
No.2、Collet
1、
Abnormal situation caused by improper setting of collet
To choose the right collet is the key issue in improving the product’s quality. LED is different
00000000000000
from other electronic components, which is not only about electrical output but also for optical output.
0
This characteristic made LED more fragile in the process of SMT. If the collet’s lowering down height
0
is not well set, it will bring damage to the gold wire at the time of collet’s picking up and loading which
0
will cause the LED fail to light up, light up now and then or other quality problems
2、
How to choose the collet
During SMT, please choose the collet that has larger outer diameter than the lighting area of
lens, in case that improper position of collet will damage the gold wire inside the LED. Different collets
fit for different products, please refer to the following pictures cross out:.

larger than the lighting area

Picture 2（×）
3、How to set the height of collet
The reason why for top view SMD, the height of collet before it presses downward will
directly affect the quality of products during SMT is that if the collect go down too
much, it will press lens and cause the distortion or breaking of gold wire. The setting
of collet position should follow the pictures belowed.

00000000000000
0 No.3、Other points for attention
0
A、No pressure should be exerted to the epoxy shell of the SMD under high temperature.
0
B、Do not scratch or wipe the lens since the lens and gold wire inside are rather fragile and
cross out easy to break.
C、LED should be used as soon as possible when being taken out of the original package, and
should be stored in anti-moisture and anti-ESD package.
No.4、This usage and handling instruction is only for your reference.
