Do not stress the silicone resin while it is exposed to high temperature. 2. The reflow process should not exceed 3 times. Ver. A3 SPEC-0027 13/16 Brightek 3535BS Series Precautions 1. Recommendation for using LEDs 1.1 The lens of LEDs should not be exposed to dust or debris. Excessive dust and debris may cause a drastic decrease in the luminosity. 1.2 Avoid mechanical stress on LED lens. 1.3 Do not touch the LED lens surface. It would affect the optical performance of the LED due to the LED lens' damage. 1.4 Pick & place tools are recommended for the remove of LEDs from the factory tape & reel packaging 2. Lens handling Please follow the guideline to pick LEDs. 2.1 Use tweezers to pick LEDs. 2.2 Do not touch the lens by using tweezers. 2.3 Do not touch lens with fingers. 2.4 Do not apply more than 4N (400gw) directly onto the lens. Correct ( ) Wrong ( X ) 3. Lens cleaning In the case which a small amount of dirt and dust particles remain on the lens surface, a suitable cleaning solution can be applied. 3.1 Try a gentle wiping with dust-free cloth. 3.2 If needed, use dust-free cloth and isopropyl alcohol to gently clean the dirt from the lens surface. Ver. A3 SPEC-0027 14/16 Brightek 3535BS Series 3.3 Do not use other solvents as they may directly react with the LED assembly. 3.4 Do not use ultrasonic cleaning which will damage the LEDs. 4. Carrier tape handling The following items are recommended when handling the carrier tape of LEDs. 4.1 Do not twist the carrier tape. 4.2 The inward bending diameter should not be smaller than 6cm for each carrier tape. 4.3 Do not bend the tape outward. 5. Storage 5.1 The moisture-proof bag is sealed The LEDs should be stored at 30C or less and 90%RH or less. And the LEDs are limited to use within one year, while the LEDs is packed in moisture-proof package with the desiccants inside. 5.2 The moisture-proof bag is opened The LEDs should be stored at 30C or less and 60%RH or less. Moreover, the LEDs are limited to solder process within 168hrs. If the humidity indicator card shows the pink color in 10% even higher or exceed the storage limiting time since opened, that we recommended to baking LEDs at 60C at least 24hrs. To seal the remainder LEDs return to the moisture-proof bag, it's recommended to be with workable desiccants. Ver.
