Greatek Electronics advances Taiwan+1 plan with acquisition of Onsemi Philippines packaging plant

PTI’s acquisition of onsemi’s Philippine packaging facility is less about capacity expansion and more a strategic hedge against Taiwan, China’s geopolitical exposure. This move accelerates the migration of mature-node back-end manufacturing to Southeast Asia, pressuring ASEAN-laggard OSATs like SPIL to fast-track their Vietnam/Malaysia plans or risk client attrition. Technically, onsemi’s expertise in automotive-grade SiC/IGBT packaging fills PTI’s reliability gap, elevating its qualification for NVIDIA and Tesla supply chains. However, heightened scrutiny under the U.S. CHIPS Act may trigger CFIUS review if the plant handles sensitive U.S. customer products, raising compliance overhead. Within 18 months, 'Taiwan+1' will evolve from reactive diversification to proactive integration, establishing a dual-hub model—Philippines and Mexico—that erodes Taiwan, China’s irreplaceability in global back-end manufacturing.
