Failure analysis of an orange LED damaged by electrostatic discharge.

We will introduce a comparison of brightness and characteristics between good products and ESD-damaged products, along with examples of luminescence analysis using EMS microscopy!

We conduct failure analysis of orange LEDs that have been damaged by electrostatic discharge (ESD). LEDs that have been destroyed in ESD testing and show a decrease in luminous intensity can be analyzed using emission luminescence and the IR-OBIRCH method, allowing us to clarify the failure phenomena. We have examples such as "Comparison of brightness and characteristics between good products and ESD-damaged products" and "Luminescence analysis using emission microscopy." [Analysis Examples] ■ Comparison of brightness and characteristics between good products and ESD-damaged products - By polishing the lens part of a bullet-type LED to flatten it, dark areas were observed during brightness comparison. ■ Luminescence analysis using emission microscopy - In ESD-damaged products, dark areas were observed under forward bias, while only the damaged areas emitted light under reverse bias. ■ IR-OBIRCH and SEI analysis - Detailed damage locations were identified through IR-OBIRCH analysis of ESD-damaged products. *For more details, please refer to the PDF document or feel free to contact us.
