JCET sets US$1.4bn capex for AI packaging expansion as China orders stay strong

JCET’s $1.4B capex isn’t mere capacity expansion—it’s a strategic play for leadership in AI-driven advanced packaging nodes. This move will directly stimulate demand for domestic ABF substrates, high-density interconnects, and test equipment, forcing upstream material suppliers to compress qualification cycles. Amid ongoing U.S. export controls on semiconductor tools, while this bolsters China’s supply chain resilience, it also elevates compliance costs and yield risks from substituting U.S.-origin equipment. Competitors like ASE and Amkor will likely accelerate CoWoS-like capacity builds in Southeast Asia to retain global clients, while Taiwan, China-based OSATs face pressure from mainland customer reshoring. Over the next 18 months, advanced packaging will become the new geopolitical battleground—oversupply looms in legacy segments, but survival hinges on mastering 2.5D/3D integration for HBM3e/4.
