AEC-Q104 is a widely recognized qualification standard developed for the qualification of Multi-Chip Modules (MCM) used in automotive applications. A multi-chip module comprises multiple electronic components integrated into a single package to perform a specific function. This standard was developed by the Automotive Electronics Council (AEC), established in the 1990s by Chrysler, Ford, and General Motors. AEC-Q104 standard ensures improved reliability and durability of multi-chip modules to withstand the harsh conditions in the automotive industry. It contributes to vehicle safety and performance, ensuring that integrated electronic components function reliably throughout their operational lifespan.
