The AEC-Q102 standard is a qualification standard developed specifically for optoelectronic components to ensure reliability, safety, and performance in harsh automotive environments. This includes exposure to extreme temperatures, humidity, and various mechanical stresses. The AEC-Q102 standard was developed by the Automotive Electronics Council (AEC), established in the 1990s by Chrysler, Ford, and General Motors. It dictates the test conditions, methods, and acceptance criteria that optoelectronic components such as light-emitting diodes (LEDs), laser diodes, photodiodes, and phototransistors are required to pass, to be used in the automotive industry.

AEC-Q102 Stress Test Qualification and Revisions

AEC-Q102 standard outlines various stress tests for ensuring the reliability of optoelectronic components

Reference Standard	Revision	Test Item Details
AEC-Q102	A	Failure Mechanism-Based Stress Test Qualification for Optoelectronic Semiconductors in Automotive Applications
AEC-Q102-001	Initial Release	Dew Test
AEC-Q102-002	Initial Release	Board Flex Test
AEC-Q102-003	Initial Release	Optoelectronic Multichip Modules (OE-MCMs)

AEC-Q102 Temperature Grading Systems

AEC-Q102 standard categorizes optoelectronic components based on the operating temperature range

Grade	Operating Temperature Range	Applications
0	-40°C to +150°C	Powertrain, exhaust systems, high-temp areas (under the hood)
1	-40°C to +125°C	Control modules, sensors in moderate temp areas (near engine)
2	-40°C to +105°C	Cabin electronics, infotainment systems
3	-40°C to +85°C	Protected areas, low-demand automotive electronics
4	0°C to +70°C	Non-critical systems, consumer-grade electronics in vehicles
