The co-located 21st IMPACT-IAAC conference opens Oct 19 at the Grand Hilai Taipei and is expected to feature nearly 350 technical presentations and more than 1,500 industry and academic attendees, expanding for the first time to two Nangang halls. Sessions centre on AI computing and system integration, next-generation packaging and substrates (glass substrates, panel-level packaging, hybrid bonding, chiplets), and thermal management, reliability and smart manufacturing.
