The recommended storage temperature range is 5C to 30C and a maximum humidity of 50%. (2) Use Precaution after Opening the Packaging. Pay attention to the following: a. Recommend conditions after opening the package - Sealing - Temperature : 5 ~ 40℃ Humidity : less than RH30% b. If the package has been opened more than 4 week or the color of the desiccant changes. (3) For Filament PKG Because of the special structure of the Filament PKG, please follow the below notes when inspection and spot welding: a. When testing the incoming material, the test stick should not direct contact with the silicone surface. b. Spot welding workshop temperature should keep 23-25 degrees, humidity below 60% RH (avoid using sweat hands to handle silicone surface of the filament PKG when in hot temperature). c. Spot welding operator should not have long fingernails, should wear finger sleeve during the process. d. When pick filament PKG by hand, should use the finger belly touch the adhesive surface, do not clip the filament chip by fingertips with long nails. e. The unpacked filament PKG that not finished welding should be put into the drying cabinet or oven, the parameters are set as follows: - Drying cabinet set parameters: 23-25 degrees, humidity 30% -35% RH (preferred); - Oven set Parameters: 60-65 degrees; - Unpacked filament PKG that not used in case of holiday leave, suggest re-evacuated storage f. Make sure the product surface clean. If there is something sprayed on the surface, please clean It with Ethyl alcohol. g. Dust sensitivity silicone resin need containers having cover for storage. h. The recommended storage conditions are temperature 5 to 30 and 70%RH or less. I. The appearance and specifications of the product may be modified for improvement without notice. (4) Radioactive exposure is not considered for the products listed here in. (5) It is dangerous to drink the liquid or inhale the gas generated by such products when chemically disposed of. Rev0.2, Mar., 2017 11 www.seoulsemicon.com Product Data Sheet SFW8C3XX Precaution for Use (6) This device should not be used in any type of fluid such as water, oil, organic solvent and etc. When washing is required, IPA (Isopropyl Alcohol) should be used. (8) When the LEDs are in operation the maximum current should be decided after measuring the package temperature. (9) LEDs must be stored properly to maintain the device. If the LEDs are stored for 3 months or more after being shipped from Seoul Semiconductor, a sealed container with vacuum atmosphere should be used for storage. (10) The appearance and specifications of the product may be modified for improvement without notice. (11) Long time exposure of sun light or occasional UV exposure will cause silicone discoloration. (12) Attaching LEDs, do not use adhesive that outgas organic vapor. (13) The driving circuit must be designed to allow forward voltage only when it is ON or OFF. If the reverse voltage is applied to LED, migration can be generated resulting in LED damage. (14) Please do not touch any of the circuit board, components or terminals with bare hands or metal while circuit is electrically active. (15) VOCs (Volatile organic compounds) emitted from materials used in the construction of fixtures can penetrate silicone encapsulants of LEDs and discolor when exposed to heat and photonic energy. The result can be a significant loss of light output from the fixture. Knowledge of the properties of the materials selected to be used in the construction of fixtures can help prevent these issues. (16) LEDs are sensitive to Electro-Static Discharge (ESD) and Electrical Over Stress (EOS). Below is a list of suggestions that Seoul Semiconductor purposes to minimize these effects. Rev0.2, Mar., 2017 12 www.seoulsemicon.com Product Data Sheet SFW8C3XX Precaution for Use a. ESD (Electro Static Discharge) Electrostatic discharge (ESD) is the defined as the release of static electricity when two objects come into contact. While most ESD events are considered harmless, it can be an expensive problem in many industrial environments during production and storage. The damage from ESD to an LEDs may cause the product to demonstrate unusual characteristics such as: - Increase in reverse leakage current lowered turn-on voltage - Abnormal emissions from the LED at low current The following recommendations are suggested to help minimize the potential for an ESD event. One or more recommended work area suggestions: - Ionizing fan setup - ESD table/shelf mat made of conductive materials - ESD safe storage containers One or more personnel suggestion options: - Antistatic wrist-strap - Antistatic material shoes - Antistatic clothes Environmental controls: - Humidity control (ESD gets worse in a dry environment) b. EOS (Electrical Over Stress) Electrical Over-Stress (EOS) is defined as damage that may occur when an electronic device is subjected to a current or voltage that is beyond the maximum specification limits of the device. The effects from an EOS event can be noticed through product performance like: - Changes to the performance of the LED package (If the damage is around the bond pad area and since the package is completely encapsulated the package may turn on but flicker show severe performance degradation.) - Changes to the light output of the luminaire from component failure - Components on the board not operating at determined drive power Failure of performance from entire fixture due to changes in circuit voltage and current across total circuit causing trickle down failures. It is impossible to predict the failure mode of every LED exposed to electrical overstress as the failure modes have been investigated to vary, but there are some common signs that will indicate an EOS event has occurred: - Damaged may be noticed to the bond wires (appearing similar to a blown fuse) - Damage to the bond pads located on the emission surface of the LED package (shadowing can be noticed around the bond pads while viewing through a microscope) - Anomalies noticed in the encapsulation and phosphor around the bond wires. - This damage usually appears due to the thermal stress produced during the EOS event.

To help minimize the damage from an EOS event Seoul Semiconductor recommends utilizing: - A surge protection circuit - An appropriately rated over voltage protection device - A current limiting device Rev0.2, Mar., 2017 14 www.seoulsemicon.com Product Data Sheet SFW8C3XX Company Information Published by Seoul Semiconductor © 2013 All Rights Reserved.
