Effects of moisture absorption ●Sanken chip LEDs are designed for surface mounting (SMD). However, interfacial separation may occur during dip soldering, depending on the moisture absorption of the resin. This phenomenon is commonly called “Popcorn effect.” It is caused by vaporization of the resin’s absorbed moisture due to sudden thermal change, and cause interfacial separation. ●Interfacial separation may affect the light transmission efficiency, causing the light intensity to drop. 2. Moisture-proof packing ●To minimize moisture absorption before use, Sanken bakes the chip LEDs and packs them in moisture-proof packing. ●Laminated aluminum, which has high moisture-resistance, is used for the moisture-proof packing. ●For additional protection against moisture absorption, silica gel is added to each packing. 3. Storage period after unpacking ●The chip LEDs must be dip-soldered within seven days after opening the moisture-proof packing. 4. Storage of unused chip LEDs ●Repack unused chip LEDs with their moisture-proof packing, fold to close any opening and then store in a dry place.
