S3535-DR100-265nm-FL LEDs Specifications Table 7. Failure criteria Criteria # Failure Criteria Forward voltage(Vf) Notes: 1. LED packages may absorb moisture; therefore, you must store the LEDs in moisture-proof bags. 2. To avoid failure, solder the LEDs onto PCBs within 24 hours after opening the moisture-proof bags. 3. If not used within 48 hours, Bolb recommends placing open bags into a nitrogen purge dry box.

S3535-DR100-265nm-FL LEDs Specifications 10. Handling procedures: ESD protection Workplace setup should follow the recommendations given in JEDEC standard document JESD625B “Requirements for Handling Electrostatic-Discharge-Sensitive (ESDS) Devices” or IEC 61340-5-1,2 and 3. In addition, properly train operators to handle UV-B flip chips according to the guidelines listed below: • Always wear conductive wrist straps when handling Bolb UV-C LEDs—both on or off boards. Continuously monitor the conductive straps to ensure that they start and remain grounded. • Use an ion blower to neutralize...
