ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low forward
voltage, or “no lightup” at low currents. To verify for ESD damage, check for “lightup” and Vf of the suspect
LEDs at low currents.
Suggested checking list :
Training and Certification
Static-Safe Workstation & Work Areas
Personnel Grounding
Static Electricity or power surge will damage the LED.
Suggestions to prevent ESD damage.
White LED is materialized by combining blue LED and phosphors. Color of White LED is changed a little by an
operating current.
The appearance and specifications of the product may be modified for improvement, without prior notice.
3. Are audit records complete and on file?
1. Every ESDS items identified by EIA-471 labels on item or packaging?
3. No static charge generators (e.g. plastics) inside shielding containers with ESDS items?
4. All flexible conductive and dissipative package materials inspected before reuse or recycles?
1. Audit result reported to entity ESD control coordinator?
2. Corrective action from previous audits completed?
Use a conductive wrist band or anti-electrostatic glove when handling these LEDs.
1. Everyone working in a static-safe area is ESD-certified?
2. Training records kept and re-certification dates monitored?
1. Static-safe workstation or work-areas have ESD signs?
2. All surfaces and objects at all static-safe workstation and within 1 ft measure less than 100V?
3. All ionize activated, positioned towards the units?
4. Each work surface mats grounding is good?
1. Every person (including visitors) handling ESD sensitive (ESDS) items wears wrist strap, heel strap or
2. If conductive footwear used, conductive flooring also present where operator stand or walk?
3. Garments, hairs or anything closer than 1 ft to ESD items measure less than 100V*?
4. Every wrist strap or heel strap/conductive shoes checked daily and result recorded for all DLs?
5. All wrist strap or heel strap checkers calibration up to date?
Work tables , storage racks , etc. should be properly grounded .
Use ion blower to neutralize the static charge which might have built up on surface of the LED's plastic
2. All ESDS items completely inside properly closed static-shielding containers when not at static-safe
lens as a result of friction between LEDs during storage and handling.
All devices , equipment , and machinery must be properly grounded.
