Chunghwa Leading Photonics’ push into SWIR testing isn't just opportunistic—it's a necessary response to the physical limits of advanced packaging. As chiplet densities escalate, electrical probing fails to capture micro-defects, making SWIR-based optical inspection indispensable. This shift forces upstream upgrades in InGaAs sensors and laser sources, but also heightens Taiwan, China’s exposure to U.S. and Japanese optical component dependencies—especially if BIS expands controls on high-resolution spectrometers, potentially inflating supply chain costs by over 15%. Competitors like AIXTRON and SCREEN may counter with integrated opto-electronic test platforms, squeezing standalone vendors. Within 18 months, SWIR adoption will extend beyond HBM/CoWoS into automotive and edge AI chips, establishing a 'test-driven design' paradigm that compels co-optimization between EDA and packaging flows.
