What happened
K&S (Kulicke and Soffa) has expanded its TCB (thermal compression bonding) advanced packaging roadmap, targeting growth in CPO (co-packaged optics) and CoPoS (chip-on-package-on-substrate) applications.
Why it matters
This move positions K&S to address emerging advanced packaging demands, where TCB is a key technology for integrating chiplets and optical components in high-performance computing and AI systems.
What to watch
The roadmap’s success hinges on whether CPO and CoPoS adoption moves beyond early designs into high-volume data center and AI accelerator production, where TCB demand would materialize. Watch for any announced production timelines or design wins from leading AI chipmakers.

K&S's expanded TCB roadmap responds to growing complexity in advanced packaging. Traditional packaging methods face limits as chip designs incorporate more heterogeneous components. TCB offers finer pitch connections needed for integrating chiplets and photonics. CPO and CoPoS represent next-generation approaches. CPO aims to bring optics closer to compute to improve bandwidth and power efficiency. CoPoS addresses the challenge of stacking multiple dies with high interconnect density. K&S's focus on these areas suggests the company expects demand to rise alongside AI infrastructure buildouts. Success depends on industry adoption of these architectures, which could shape future packaging equipment demand.
