Panel-Level Packaging’s Second Wave Meets Engineering Reality

Panel-level packaging is gaining traction due to economic pressures and the increasing size of AI accelerators and HPC packages. Glass substrates are being explored to address warpage and dimensional stability issues, but they introduce new failure modes that require material solutions. Challenges in panel-level processing include materials and process integration, not just packaging problems. The industry is moving towards panels driven by economic and technological shifts, but solving these challenges requires a holistic approach.
