PSK HOLDINGS INC. is a South Korea-based company primarily engaged in the development, manufacture, and distribution of semiconductor manufacturing equipment, with a specialized focus on advanced packaging and back-end processing solutions. Founded in 1990 and headquartered in Hwaseong-si, Gyeonggi-do, South Korea, the company serves integrated device manufacturers, foundries, and outsourced semiconductor assembly and test providers across domestic and international markets, including Greater China, Taiwan, Southeast Asia, and the United States. The company's product and service portfolio comprises: dry descum systems, including plasma photoresist descum equipment utilized for residue removal in wafer-level packaging, panel-level packaging, through-silicon via processing, and high-bandwidth memory architectures; reflow systems, featuring vacuum reflow and fluxless reflow systems engineered for micro-bump solder reflow, flip-chip interconnection, and thermal warpage prevention; wafer edge and surface treatment systems; and equipment conversion kits, consumable components, maintenance, and engineering support services. In recent developments, PSK HOLDINGS INC. has expanded its supply of high-precision descum equipment to major global memory manufacturers driven by the accelerated production of high-bandwidth memory modules and 2.5D/3D artificial intelligence semiconductor packaging. The company has also advanced its commercial rollout of next-generation fluxless vacuum reflow tools tailored for fine-pitch chiplet packaging, while increasing its capital expenditures in South Korean production facilities and expanding overseas technical support networks to address growing demand across advanced semiconductor packaging hubs.
