ISU Petasys Co., Ltd. manufactures and sells ultra-multilayer printed circuit boards (PCBs) worldwide. The company specializes in high-integration PCBs for network equipment including switches and routers; server and storage systems; supercomputers (HPC); aerospace applications; IC testers such as probe cards, load boards, and burn-in boards; advanced driver assistance systems (ADAS) RF radar; and radio frequency PCBs. Founded in 1972 with PCB operations commencing in 1989, ISU Petasys is headquartered in Nongong-eup, Dalseong-gun, Daegu, South Korea, and operates globally with sales in the United States, China, Taiwan, Thailand, Mexico, Malaysia, and other regions. ISU Petasys, a subsidiary of ISU Group, employs approximately 1,186 people and reported record revenue of KRW 836.9 billion in 2024 from its core PCB manufacturing segment. In late 2024, the company announced a KRW 5.5 trillion rights offering to fund a fifth factory for multi-layer boards (MLB) targeting AI semiconductor demand, existing plant expansions, and an intended acquisition of a 30.1% stake in JEIO Co., Ltd. for advanced materials diversification, though the JEIO transaction was cancelled in early 2025; construction of the fifth plant advances toward completion in the second half of 2027.
