The relability tests were designed to evaluate both package integrity as well as workability of product preformance over time 2. All samples have done well by competed test required and passed all the qualitication criteria with zero failure. From design standpoint, this package is robust enough to meet its datasheet condigions. 3. Based on the good result shows on the above test, this prduct is qualified and released for market. 21.05.2012 VL380-3528 4 of 6 Surface Mount Condition In automatic mounting of the SMD LEDs on printed circuit boards, any bending, expanding and pulling forces or shock against the SMD LEDs should be kept min. to prevent them from electrical failures and mechanical damages of the devices. Soldering Reflow 1. Soldering of the SMD LEDs should conform to the soldering condition in the individual specifications. 2. SMD LEDs are designed for Reflow Soldering. 3. In the reflow soldering, too high temperature and too large temperature gradient such as rapid heating/cooling may cause electrical & optical failures and damagesof the devices. 4. We cannot guarantee the LEDs after they have been assembled using the solder dipping method. 5. There is possibility that the brightness of LEDs is decreased, which is influenced by heat or ambient atmosphere during reflow. It is recommended to use the nitrogen reflow method. 6. After LEDs have been soldered, repairs should not be done. As repair is unavoidable, a double-head soldering iron should be used. It should be confirmed beforehand whether the characteristics of the LEDs will be damaged by repairing or not. 7. Reflow soldering should not be done more than two times. (1) Lead Solder (2) Lead-Free Solder (3) Manual Soldering Conditions a) Lead Solder: max. 300°C for max. 3sec., and only one time. b) Lead –Free Solder: max. 350°C for max. 3sec., and only one time. 21.05.2012 VL380-3528 5 of 6 Precaution for Use 1. Cautions • This device is a UV LED, which radiates UV light during operation. • DO NOT look directly into the UV light or look through the optical system. To prevent in adequate exposure of UV radiation, wear UV protective glasses. 2. Static Electricity • The LEDs are very sensitive to Static Electricity and surge voltage. So it is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs. • All devices, equipment and machinery must be grounded properly. It is recommended that precautions should be taken against surge voltage to the equipment that mounts the LEDs. 3. Heat Generation • The powered LEDs generate heat. Heat dissipation should be considered in the application design to avoid the environmental conditions for operation in excess of the absolute maximum ratings. 21.05.2012 VL380-3528 6 of 6
