AEC-Q102 LED Qualification ReviewStatus – AEC-Q102 ready to be published

� Dedicated for discrete optoelectronic semiconductors.

− LED (visible & IR)

− Laser

− Photo Diodes

− Photo Transistors

� Valid for exterior and interior automotive application


5

AEC-Q102 LED Qualification ReviewContent - Test Setup

� Closer look to the test board assembly

� Detailed definition of failure criteria

� Enhanced criteria for pre- and post-stress tests to detect latent failures

− Test not only at room but simple light / no light also at high & low temperature

− Alternative: failure detection during stress test

� Documents for communication (CDCQ; qualification plan, test report)
