Infineon boosts Thailand's chip drive - Bangkok Post

Infineon's Thailand push is not a fab story—it is a back-end geographic anchor for power-module assembly. Shifting SiC and IGBT packaging, potting, and test to Thailand compresses 800V EV-platform delivery cycles by 15-20%, directly pressuring Tier-1 BOM costs at Bosch, Continental, and peers. On the technical chain, SiC thermal-substrate bonding has an extremely narrow yield window; if Thailand clears automotive-grade qualification, it erodes the pricing leverage of ASE and Amkor across the Southeast Asian OSAT cluster. On compliance, Thailand's 13-year tax holiday is attractive, but Infineon's SiC epi-wafers still depend on equipment and materials from Taiwan, China and Japan. As BIS export-control lists expand, material-traceability costs will keep climbing. Competitive response is predictable: ST and onsemi will likely follow within six months; StarPower and CRRC Times Electric will accelerate Vietnam and Malaysia hedges. Yet Infineon's real moat is its CoolSiC patent portfolio and AEC-Q certification depth—Thailand is a single move, not the endgame. Over 12-24 months, Southeast Asia will evolve from a packaging enclave into a regional power-module delivery hub, but front-end wafer manufacturing remains locked in Taiwan, China, Japan, and Germany. Thailand's ceiling is assembly and test, not design and fabrication.
