Failure analysis of electrostatic discharge damaged orange LED.

We will introduce a comparison of the brightness and characteristics of good products and electrostatic discharge (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 during ESD testing and show a decrease in luminous intensity can be analyzed using emission photometry 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 "Emission analysis using an emission microscope." [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, a brightness comparison was conducted, revealing dark areas. ■ Emission analysis using an emission microscope - In the 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.
