What will be the challenges of advanced packaging and circuit board reliability

Big data and artificial intelligence are making humans more dependent on electronic systems, and will make reliability deficiencies even more deadly. At DesignCon 2020 recently, I had the opportunity to learn how ANSYS enables engineers to design highly r
