Safety z Customers should comply with the laws and public regulations concerning safety. z Operation temperature or driving current may affect emission color. Please check sorting condition and characteristic diagram to estimate color shift. z Moisture and dust may affect reliability issues. Do not open the shielding bag under humid or dirty environment. z When installing the product in PCB, the device should not contact with other components. z Do not apply force to the LED under high-temperature condition. z Do not apply friction to the LED using hard material. z Avoid exposure to chemicals which may dissolve the LED package and the epoxy. z Use IPA(Isopropyl Alcohol) as a solvent when washing is required. 9-2. z Static Electricity These products are sensitive to static electricity. Anti–electrostatic glove or wristband is recommended when handling the LEDs. z A protection device should be installed in the LED driving circuit to eliminate or minimize the surge current effect. z Proper grounding of Products, use of conductive mat, semi-conductive working uniform and shoes, and semi-conductive containers are considered to be effective as countermeasures against static electricity and surge. 9-3. z Storage Condition Before opening the anti-static shielding package: LEDs should be kept at 30°C or less and RH 80% or less. Maximum acceptable storage period is 6 months. z After opening the anti-static shielding package: LEDs should be kept at 30°C or less and RH 70% or less. LEDs should be soldered within 7 days after opening the package. - 12 - 3528 Flash White Color SMD Type LED 10.
