LED failure analysis

Applying advanced sample preparation techniques and failure analysis equipment for semiconductors! Investigating the causes of non-lighting and brightness degradation.

In our "LED Failure Analysis," we conduct failure analysis of LEDs using advanced sample preparation techniques and semiconductor failure analysis equipment to investigate the causes of non-lighting and brightness degradation. In the "LED Defect Mode Isolation," we performed lighting tests after lens polishing and observed the resin of the LED, polishing it to stages a, b, and c, conducting lighting observations for (a) and (b), and optical observations of the chip through the resin for (c). Additionally, we also have categories such as "electrically normal," "open, high resistance," etc. 【Initial Diagnosis Items for LED Packages】 ■ Electrical characteristic measurement ■ Appearance observation ■ Lens polishing/package internal optical observation ■ Lighting test (brightness distribution observation) *For more details, please refer to the PDF materials or feel free to contact us.
