Automotive Electronics Reliability – Challenges and Opportunities

 

Course Objective and Outline:

The modern car has increased semiconductor content and dollar value.  Semiconductors enable the majority of innovations in automotive.  The increased emphasis on autonomous driving and the electrification of vehicles has resulted in enormous changes for semiconductors and packaging.  The design, materials, and reliability strategies for automotive electronics will be presented.  Electronics are increasingly being used in automotive platforms for various mission-critical and safety-critical activities, such as guidance, navigation, control, charging, sensing, and operator interaction.  Over the last two decades, automotive platforms have expanded to incorporate hybrid and fully electric vehicles.  Much of the electronics is located under the car’s hood or in the trunk, where temperatures and vibration levels are far higher than in consumer office applications.  During the vehicle’s use-life, electronics in the automotive underhood may be exposed to sustained high temperatures of 125-150°C for extended periods.  The Automotive Electronics Council (AEC) has graded electronics for automotive purposes into four categories: grade 0, grade 1, grade 2, and grade 3.  Grade-0 components have the most demanding criteria of the four grade categories, with predicted power temperature cycling ranging from -40°C to +150°C for 1000 cycles and ambient temperature cycling ranging from -55°C to +150°C for 2000 cycles.  Furthermore, the grade-0 components are expected to be capable of sustaining high-temperature storage for 1000 hours at 175°C.  With the introduction of new packaging architectures, packaging applications have continued to evolve, allowing for powerful computing on mobile automobile platforms.  New materials and integration technologies have also emerged, allowing for tighter integration of electronics sensing and processing into the structural characteristics of the vehicle.  The automobile platform faces a series of constraints particular to the real-time context for enabling sophisticated functionality. 

 

Specifically, the course will encompass the following topics:

 

1.       Role of electronics on the automotive platform

2.       Automotive environments

3.       Zero-Defects

4.       Second-Level Solder Interconnect Design Considerations

5.       Copper Wirebond Interconnects

6.       Advanced Packaging Interfaces

7.       Vibration Effects

8.       Sustained High Temperature and Wide Thermal Extremes

9.       Corrosion Propensity

10.    Accelerated Testing

 

Who Should Attend:

The goal of the course is to provide the students with a comprehensive understanding of the materials and reliability considerations in the design of electronics for operation in the automotive platform.  The course is intended to have an intermediate degree of difficulty to serve as an introduction for engineers and managers looking to design electronics for operation in the automotive underhood.
