. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent
damage to the device. This is a stress rating only and functional operation of the device at
these or other conditions above those indicated in the operations section for expended periods
of time may affect reliability.
2. In its maximum rating diode laser operation could damage its performance or cause potential
safety hazard such as equipment failure.
3. Electrostatic discharge is the main reason for the laser fault of the diode. Take effective
precautions against ESD. When dealing with laser diodes, use the wrist strap, grounding work
surface and strict antistatic technology.

Note: Reflow soldering can be operated only one time. During the temperature ramp-up, no forces
may be exerted on the LD which could deform or damage them. After soldering completed, please
also do not process until the product temperature ramp down to room temperature.
VI. Treatment and protection measures
Soldering precautions
The temperature of soldering iron must be controlled under 300℃ during manual soldering. Also,

Diodes
VCSEL can be only soldered one time with the soldering time less than 3s. but, it is very hard to
control the soldering temperature and homogenize solder paste because of the smaller size of
VCSEL. In addition, it is easy to damage VCSEL structure even causes VCSEL losing efficacy. So,
we advise you to use re-flow soldering machine for operation.
Storage precautions
Our products were sealed by aluminum foil bag attaching packed desiccant, they are moisture
proof and anti-static. please handle these gently to avoid damage. At the same time, please be ready
for storage and take some moisture-proof measures to keep VCSEL away from dampness that may
causes reliability failure.
Before opening, VCSEL must be saved for at least 90 days below 30℃ with 60% RH.
After opening, VCSEL must be kept in an environment that temperature lower than 30℃ and
humidity lower than 60% RH and used up within 24 hours. When the storage humidity reaches and
exceeds 60%, the products must be dehumidified at 60 °C for more than 24 hours before use.
Others
1. Please use solder paste to cure the laser diode.
2. Please make sure that the heat of LD has been completely conducted to metal shell, to
avoid affecting the optical power output.
3. This LD can be only used in constant voltage and current.
4. Operating voltage and current, refer to the table in paragraph
Ⅱ.
5. Please do not aim the laser to people or animal.
6. You can observe the laser spot through an image monitoring equipment.
7. Please do not touch LD surface by naked hands or squeeze the sealant on LD surface, or it
may cause wrong optical angle and distorted laser spot, even damage the LD.
8. Please use ceramic suction nozzle to absorb the LD, so as to avoid LD sticking to the nozzle.
9. Please add a 0.02 s blowing action after locating the laser diode to aluminum substrate.
