24 hours. ESD (Electrostatic Discharge )-Protection A LED (especially the Blue、White and Green product) is an ESD sensitive component, and static electricity or power surge will damage the LED. ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low forward voltage, or "no light-up" at low currents, etc. Some advice as below should be noticed: 1. A conductive wrist strap or anti-electrostatic glove should be worn when handling these LEDs. 2. All devices, equipment, machinery, work tables and storage racks, etc. must be properly grounded.

Use ionizer to neutralize the static charge during handling or operating. 5. All surfaces and objects within

1 ft close to LEDs measure less than 100V. Cleaning Use alcohol-based cleaning solvents such as IPA (isopropyl alcohol) to clean LEDs if necessary. Soldering 1. Soldering condition refer to the draft "Soldering Profile Suggested" on page 1. 2. Reflow soldering should not be done more than

2 times. 3. Manual soldering is only suggested on repair and rework. The maximum soldering temperature should not exceed 300°C within

3 sec. And the maximum capacity of soldering iron is 30W in power. 4. During the soldering process, do not touch the lens at high temperature. 5. After soldering, any mechanical force on the lens or any excessive vibration shall not be accepted to apply, also the circuit board shall not be bent as well. Others 1. The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment, communication equipment and household applications).Consult Harvatek's Sales in advance for the applications in which exceptional reliability is required, particularly when the failure or malfunction of the LEDs may directly jeopardize life or health. (such as in aviation, transportation, traffic control equipment, medical and life support systems and safety devices). 2. The light output from the high luminous intensity LEDs may cause injury to human eyes when viewed directly. 3. The appearance and specifications of the product may be modified for improvement without prior notice.
